Newswise CHICAGO (June 10, 2022): Anthony Atala, MD, FACS, Winston-Salem, North Carolina, will be presented with the 2022 Jacobson Innovation Award of the American College of Surgeons (ACS) at a dinner held in his honor this evening in Chicago. He is currently the George Link, Jr. Professor and Director of the Wake Forest Institute for Regenerative Medicine (WFIRM) and the W. H. Boyce Professor and Chair of Urology at the Wake Forest University School of Medicine.

The international surgical award from the ACS honors living surgeons who are innovators of a new development or technique in any field of surgery. It is made possible through a gift from Julius H. Jacobson II, MD, FACS, and his wife Joan. Dr. Jacobson is a general vascular surgeon known for his pioneering work in the development of microsurgery.

Dr. Atala is a pediatric urologist, researcher, professor, and mentor who is renowned for developing foundational principles for regenerative medicine research, which holds great promise for people who require tissue substitution and reconstruction. Dr. Atala and his team successfully implanted the worlds first laboratory grown bladder in 1999.

Dr. Atalas remarkable work has expanded, and today, WFIRM is a leader in translating scientific discovery into regenerative medicine clinical therapies. He currently leads an interdisciplinary team of more than 450 researchers and physicians. Beyond many other world firsts, WFIRM has also developed 15 clinically used technology-based applications, including muscle, urethra, cartilage, reproductive tissues, and skin. Currently, the Institute is working on more than 40 tissues and organs.

Through Dr. Atala's vision, ingenuity, and leadership, the WFIRM team has developed specialized 3-D printers to engineer tissues. This work is accomplished by using cells to create various tissues and organs, including miniature organs called organoids to create body-on-a-chip systems. Dr. Atala and his team also discovered a stem cell population derived from both the amniotic fluid and the placenta, which are currently being used for clinically relevant research applications.

Dr. Atala's theory is that every cell within the human body should be capable of regeneration. What reproduces naturally inside the body should also have the same capabilities of reproduction outside of the body. According to Dr. Atala, the key benefit to the approach of cell and tissue regeneration is that a patient will not reject their own cells or tissue, which is always a concern related to traditional organ match transplantation.

Honors and awards Dr. Atalas innovative work has been recognized as one of Time magazine's Top 10 Medical Breakthroughs in 2007, Smithsonian's 2010 Top Science Story of the Year, and U.S. News & World Report's honor as one of 14 top Pioneers of Medical Progress in the 21st Century. He has been named by Scientific American as one of the world's most influential people in biotechnology, by Life Sciences Intellectual Property Review as one of 50 Key Influencers in the Life Sciences Intellectual Property arena, and by Nature Biotechnology as one of the top 10 Translational Researchers in the World.

Dr. Atala was elected to the Institute of Medicine of the National Academies of Sciences (now the National Academy of Medicine) in 2011 and inducted into the American Institute for Medical and Biological Engineering. In 2014, he was inducted into the National Academy of Inventors as a Charter Fellow and has been a strong and thoughtful contributor to the ACS Surgical Forum and Surgical Research Committee. He presented the prestigious Martin Memorial Named Lecture during the ACS Clinical Congress in 2010 entitled, Regenerative Medicine: New Approaches to Health Care.

Other honors include being the recipient of the U.S. Congress-funded Christopher Columbus Foundation Award, which is bestowed on a living American that currently is working on a discovery that will significantly affect society; the World Technology Award in Health and Medicine for achieving significant and lasting progress; the Edison Science/Medical Award; and the Smithsonian Ingenuity Award.

A national leader in regenerative medicine Throughout his distinguished career, Dr. Atala has led or served on several national professional and government committees, including the National Institutes of Health Working Group on Cells and Developmental Biology, the National Institutes of Health Bioengineering Consortium, and the National Cancer Institute's Advisory Board. He is a founder of the Tissue Engineering Society, the Regenerative Medicine Society, the Regenerative Medicine Foundation, the Alliance for Regenerative Medicine, the Regenerative Medicine Development Organization, the Regenerative Medicine Manufacturing Society, and the Regenerative Medicine Manufacturing Consortium.

A prolific author and inventorDr. Atala is the editor in chief of Stem Cells-Translational Medicine and BioPrinting. He is an author or coauthor of more than 800 journal articles and has applied for or received over 250 national and international patents.

About Anthony Atala, MD, FACS

Dr. Atala was born in Lima, Peru, and moved to the United States with his family when he was a young boy. He earned a Bachelor of Arts degree from the University of Miami before attending medical school at the University of Louisville, where he also completed his surgical residency training. Near the end of his residency, he applied for a pediatric urology fellowship at Boston Children's Hospital, which was transitioning from a one-year to a two-year program to include a year of research prior to the clinical year. He embarked on a fellowship there in its new form with encouragement from Alan B. Retik, MD, FACS, founder of Boston Childrens first department of urology. Dr. Atala arrived in Boston and began attending seminars, which led him to explore whether uroepithelial cells could be grown and expanded ex vivo, comparable to skin. This additional year of research sparked what has become his career of transformational research, discovery, and innovation with his work focused on growing human cells, tissues, and organs.

Dr. Atala spent the first portion of his academic career at Harvard Medical School before being recruited in 2004 as professor and chair of the department of urology at Wake Forest School of Medicine. After moving his laboratory from Boston, he became the founding Director of the Wake Forest Institute for Regenerative Medicine, where his research and work has produced extraordinary results for nearly two decades.

Studies Test Effectiveness and Safety of Stem Cell Treatment for Urinary Incontinence

Posted: July 1, 2014 at 6:49 pm

Durham, NC (PRWEB) July 01, 2014

Medication and minimally invasive surgery to implant a sling can provide relief for millions of people who suffer from stress urinary incontinence (SUI), but not everyone responds to these therapeutic methods. A new study in the current STEM CELLS Translational Medicine tests the safety and effectiveness of stem cells as an alternative SUI treatment.

SUI results when the pelvic floor muscles, which support the bladder and urethra, weaken to the point that the muscles are not able to prevent urine from flowing when pressure is placed on the abdomen, such as when the person laughs or coughs. It occurs most often in women, due to childbirth and pregnancy.

Tissue engineering offers an attractive method to regenerate sphincter muscle, explained the studys corresponding author, Kirsi Kuismanen, from the department of obstetrics and gynecology at Tampere University Hospital (TUH) in Finland. She and her TUH colleagues teamed up with researchers from the Adult Stem Cell Group of BioMediTech in Tampere and the University of Twente in the Netherlands on the study.

Previously, various different cell sources, such as skeletal muscle-derived stem cells (SkMSCs), mesenchymal stem cells derived from bone marrow (BMSCs) and adipose stem cells (ASCs), have been studied for treating urinary incontinence. The SkMSCs and BMSCs would be a potential alternative for incontinence therapy. However, when compared to ASCs, the major limitation of SkMSCs and BMSCs is the difficulty to obtain these cells in large quantities, Dr. Kuismanen said.

The study involved five SUI patients who either did not want a sling implant or had undergone implants but they proved unsuccessful. They were treated with ASCs combined with bovine collagen gel, which is a bulking agent, and saline.

Prior to the treatment, the ASCs were isolated from subcutaneous fat and expanded for three weeks in a laboratory. The mixture of ASCs and collagen was injected in the patients who were followed for three, six and 12 months after the injections. The primary end point was a cough test to measure the effect of the treatment. Validated questionnaires were used to determine the subjective cure rate.

After six months, one out of five patients displayed a negative cough test with full bladder. At one year, the cough test was negative with three patients; two were satisfied with the results and ended their treatment for SUI. Validated questionnaires showed some subjective improvement in all five patients.

This is the first study describing the use of autologous ASCs in combination with collagen gel for female SUI treatments, Dr. Kuismanen said. Thus far, the treatment with autologous ASCs has proven safe and well tolerated. However, the feasibility and efficacy of the treatment were not optimal so additional research is needed to develop SUI injection therapies.

New treatments are needed for this common condition that affects millions of women, said Anthony Atala, M.D., editor of STEM CELLS Translational Medicine and director of the Wake Forest Institute for Regenerative Medicine. The current study, believed to be the first to evaluate adipose-derived stem cells in combination with collagen, adds to the body of knowledge about the safety and effectiveness of stem cell treatments for stress urinary incontinence.

First Study Tracking Stem Cell Treatments For Children With Spinal Cord Injuries Shows Potential Benefit

Posted: February 3, 2014 at 3:45 pm

Durham, NC (PRWEB) February 03, 2014

Previous studies have shown that multiple stem cell implantations might assist adults suffering from complete spinal cord injuries (SCI). Now a groundbreaking study released today in STEM CELLS Translational Medicine shows for the first time that children with SCI might benefit, too.

Marcin Majka, Ph.D., and Danuta Jarocha, Ph.D., led the study at Jagiellonian University College of Medicine in Krakow, Poland. "Although it was conducted on a small number of patients carrying a different injury level and type, preliminary results demonstrate the possibility of attaining neurological, motor and sensation and quality-of-life improvement in children with a chronic complete spinal cord injury through multiple bone marrow derived cell (BMNC) implantations. Intravenous implantations of these cells seem to prevent and/or help the healing of pressure ulcers," Dr. Majka said.

The study involved five children, ranging in age from 3 to 7, all of whom were patients at University Childrens Hospital in Krakow. Each had suffered a spinal cord injury at least six months prior to the start of the stem cell program and was showing no signs of improvement from standard treatments. The patients collectively underwent 19 implantation procedures with BM-derived cells, with every treatment cycle followed by an intensive four weeks of rehabilitation.

The children were evaluated over a one to six year period for sensation and motor improvement, muscle stiffness and bladder function. Any improvement in their quality of life was also noted, based on estimated functional recovery. Additionally, the development of neuropathic pain, secondary infections, urinary tract infections or pressure ulcers was tracked.

"Two of the five children receiving the highest number of transplantations demonstrated neurological and quality-of-life improvements," Dr. Jarocha said. "They included a girl who, before the stem cell implantations, had to be tube fed and needed a ventilator to breathe. She is now able to eat and breathe on her own."

The study also demonstrated no long-term side effects from the BMNCs, leading the researchers to conclude that single and multiple BMNCs implantations were safe for pediatric patients as well as adults.

Interestingly, when the scientists compared their study with those done on adults, the results did not suggest an advantage of the younger age. "This is somehow unexpected since the younger age should provide better ability to regenerate. Since the present study was done on a small number of patients, a larger study using the same methodology for pediatric and adult patients allowing a direct comparison should be performed to confirm or contradict the observation. Larger studies with patients segregated according to the type and level of the injury with the same infusion intervals should be performed to obtain more consistent data, too," Dr. Majka added.

"While this studys sample is small, it is the first to report the safety and feasibility of using bone marrow derived cells to treat pediatric patients with complete spinal cord injury," said Anthony Atala, M.D., editor of STEM CELLS Translational Medicine and director of the Wake Forest Institute for Regenerative Medicine. "The treatment resulted in a degree of neurological and quality-of-life improvement in the study participants."

Wake Forest researchers study urine as source for stem cells

Posted: August 12, 2013 at 11:50 am

WINSTON-SALEM, N.C. A daily bodily function urinating may become another option for collecting stem cells that can be transformed into regenerated tissue and organs.

Researchers with the Wake Forest Institute of Regenerative Medicine have identified stem cells in urine that can become multiple cell types. Their report is available on the website of the journal Stem Cells.

In a separate study released July 30, a group of researchers from the Guangzhou Institutes of Biomedicine and Health said they have been able to generate in mice tooth-like structures from urine-induced pluripotent stem cells.

Dr. Anthony Atala, director of the Wake Forest institute, said the use of urine-derived stem cells to regenerate human tissue and organs remains several years away.

Weve been looking at urine as a stem cell option since 2006, Atala said. Research has been so far, so good in rodents.

Being able to use a patients own stem cells for therapy is considered advantageous because they do not induce immune responses or rejection.

However, because tissue-specific cells are a very small subpopulation of cells, they can be difficult to isolate from organs and tissues.

The challenge has been getting the right cells and the right results every time, Atala said. This study reflects the promise of achieving those goals with samples that most people get rid of six times a day.

Atala and Dr. Yuanyuan Zhang, senior Wake Forest researcher on the study, said one advantage of collecting stem cells through urine is that it is a non-invasive, low-cost approach that avoids surgical procedures. Other post-birth options can require drilling into bone marrow.

The researchers say they have taken stem cells from urine and transformed them into bladder-type cells, such as smooth muscle and urothelial, the cells that line the bladder.

Stem Cells From Urine May Treat Human Diseases

Posted: August 2, 2013 at 6:46 pm

Researchers have isolated stem cells from urine as the latest potential source of treatment for human diseases. Investigators say using urine to collect and cultivate these master cells is easy and involves minimal processing.

Using proteins known as growth factors, researchers can manipulate stem cells - or master cells - to grow into any tissue in the body. Therapy using stem cells from a patients own body is desirable because it does not cause immune rejection, as can happen with tissues and organs from donors.

Currently, most scientists use a complicated process to engineer regular skin and blood cells into specific cell types. That's because there are few pure sources of master cells - apart from human embryos, whose use is quite controversial.

Researchers are now finding small numbers of stem cells in urine. Anthony Atala, director of the Wake Forest Institute for Regenerative Medicine in Winston-Salem, North Carolina, said, The advantage with urine is that you are getting approximately 2 liters of urine out every day. So you dont have to keep going back and sticking the patient [with a needle] or doing biopsies on the patient.

Reporting in the journal Stem Cells, a team from Wake Forest described how urine samples from 17 healthy individuals ranging in age from 5 to 75 contained stem cells that could be isolated, then coaxed to become smooth muscle-type cells like those that line the inside of the urethra and bladder.

Potential shown

Next, they placed the differentiated cells onto biologically-active support structures called scaffolds, made from pig intestine, then implanted the engineered tissue into mice.

After one month, the urine-derived stem cells developed biological markers of connective tissue and blood vessels, suggesting that they also had the potential to become bone, muscle, nerve or fat cells.

While urine may be a plentiful and less invasive way to obtain stem cells, some experts are skeptical about its value as a source of stem cells. Chris Mason, a regenerative medicine researcher at University College London, said there are very few usable stem cells in the liquid waste.

But he said in a Skype interview that the unusual research into urine-derived stem cells needs further scientific exploration.

W-S organization working on regenerative therapies for 40 organs, tissues – WRAL TechWire

Posted: July 3, 2022 at 1:52 am

WINSTON-SALEM Human organ transplants became possible in 1954 when a kidney became the first organ to be transplanted successfully, eventually earning Boston physician Joseph Murray the Nobel Prize.

Today, its also possible to receive a transplanted heart, lungs, liver, pancreas or intestines, as well as tissues including skin, bone, corneas, tendons, ligaments and blood vessels.

A record-high number of organ transplants 41,354 were performed in the United States in 2021, according to the United Network for Organ Sharing, a nonprofit organization that supports the nations transplant system. It was the first year that organ transplants exceeded 40,000.

Despite the progress made in organ transplantation over the last seven decades, the demand for organs still greatly out-strips the supply, a trend unlikely to reverse.

Even though organ transplants are out there, the challenge is that more patients are dying every day from organ failure, and the numbers are fairly shocking actually, saidAnthony Atala, M.D., an internationally acclaimed urologist, researcher and professor at the Wake Forest University School of Medicine. So thats where regenerative medicine comes in.

Atala is director of theWake Forest Institute for Regenerative Medicine(WFIRM), a translational research organization devoted to bringing new treatments and cures to patients with diseased or damaged organs or tissues. He highlighted WFIRMs activities and impact as the keynote speaker at Triad BioNight, a dinner and awards event held June 23 at High Point University and sponsored by the North Carolina Biotechnology Center.

Piedmont Triad bioscience leaders honored with awards at Triad BioNight

Atalas appearance at the event reinforced the mutual admiration between him and NCBiotech that dates back to his arrival at the Triad university in 2004. The Biotech Center has awarded numerous grants to various members of his lab over the years, and Atala has also served on the NCBiotech board of directors.

NCBiotech has provided $352,476.32 in grants to Wake Forest University for regenerative medicine-associated research during Atalas 18 years at the university. The Center has awarded an additional $75,883.62 in meeting, event, and educational grants for regenerative medicine-related programming during the same time, including an active $10,000 award for an upcoming meeting.

It is clear to see how over time, this regional effort has global impact, said Nancy Johnston, executive director of NCBiotechs Piedmont Triad Office. New initiatives underway indicate there is power in partnerships and place; value in investing in innovation; and the top talent it takes in this emerging field of regenerative medicine.

Regenerative Medicine The Driving Force for Dr. Anthony Atala

Atala told the crowd of nearly 400 attendees that WFIRMs scientists, technicians and physicians are working on regenerative medicine therapies for about 40 different organs and tissues, building on 15 applications that have been used in patients to date.

We have an amazing team over 450 people all working together to bring these technologies from the bench to the bedside, Atala said.

WFIRM is based in a five-story building spanning about 200,000 square feet in Winston-SalemsInnovation Quarter, a downtown district devoted to research and technology enterprises.

We do everything here, from the idea, to the concepts, to the proof of principle at the benchtop, to the preclinical work, all the way to the manufacturing of the product in an FDA-compliant facility right in this building, Atala said.

WFIRM scientists and physicians made history in 1999 when they were the first in the world to implant laboratory-grown organs into humans.Seven children with spina bifida and severely malfunctioning bladders received grafts of rudimentary bladders engineered in Winston-Salem.

Today WFIRMs multidisciplinary work uses cells, bioreactors, tissue engineering, biomaterials, 3D bioprinting, small molecules, gene editing, body-on-a-chip technologies and personalized medicine approaches to innovate new therapies and diagnostics.

NC bio startup raises $15.5M to advance 4D printing of human organs

Cell therapy the use of harvested and cultured cells to restore tissues and organs is a major thrust of WFIRMs work. The technology offers a great advantage over donated organs and tissues because it typically uses a patients own cells, thereby avoiding rejection by the bodys immune system.

Work is under way at WFIRM to use skeletal muscle cells to restore lost muscle function in patients with urinary incontinence and in patients undergoing rotator cuff repair surgery.

In both cases, skeletal muscle cells are collected from a tissue sample smaller than a postage stamp, are multiplied in the lab, and are then injected into the body to build muscle.

Researchers are also working with a type of stem cell taken from the amniotic fluid or placenta after a woman gives birth. WFIRM scientists were the first in the world to identify and characterize stem cells derived from amniotic fluid in 2007 and since then have developed techniques for isolating and expanding the cells.

These cells are very powerful, Atala said. They can grow into all three different major categories of cells that lead to every cell in your body.

WFIRM is investigating the use of these cells as potential therapies for patients with chronic kidney disease.

Cell therapy often involves the use of biomaterials that can be shaped into scaffolds that mimic the shape of a tissue or organ. Different materials can be mixed and matched for various tissue reconstruction.

One application is for helping patients with a damaged urethra, the duct that drains urine from the bladder. A tubular-shaped scaffold is coated inside and outside with muscle cells that are taken from the patient and multiplied, then the scaffold is placed in an oven-like device to encourage cell growth.

Its very much like baking a layer cake, Atala said, eliciting chuckles from the audience. Once its completed you actually put it back into the patient.

The implanted scaffold biodegrades in the body after six months, but the cells remain viable indefinitely.You end up with your very own cells, your very own bridge and your very own organ, Atala said.

WFIRM researchers have successfully engineered replacement tissues and organs of all four shapes found in the body flat structures, tubular tissues, hollow organs and solid organs.

WFIRM is also a pioneer in 3D bioprinting, the use of printer-like devices to deposit layers of living cells in three-dimensional patterns. The invention, inspired by desktop ink jet printers, brings precision and automation to the construction of tissues and organs.

Last year two teams of scientists from WFIRM used 3D bioprinting to win first and second place in NASAsVascular Tissue Challenge, a national competition to accelerate tissue engineering innovations that might benefit people on Earth today and space explorers in the future.

The WFIRM teams created lab-grown human liver tissues that were strong enough to survive and function in ways similar to those inside the body. They each used a varied 3D printing technique to construct a cube-shaped tissue about one centimeter thick and capable of functioning for 30 days in the lab.

That was a major challenge, Atala said, because anything over the size of a pinhead will not get nutrition.

Tissues in the body rely on blood vessels to supply cells with nutrients and oxygen and remove metabolic waste. Recreating this process in engineered tissue is difficult, so NASA asked teams to develop and test strategies for making tissues with functional artificial blood vessels.

Wake Forest researchers win NASA challenge to develop lab-grown human vascular tissue

The winning teams used 3D printing to create gel-like molds with a network of channels designed to maintain sufficient oxygen and nutrient levels to keep the constructed tissues alive.

The two teams collectively won $400,000 while no other team in the national competition qualified for third place.

Another WFIRM application of 3D bioprinting is body-on-a-chip technology, which applies cells onto a computer chip to mimic organs.

We can create miniature hearts, lungs, blood vessels, kidneys and brains, put them all together on a chip and actually start to screen drugs over time, Atala said.

The technology can also be used to create tumors on a chip for personalized medicine. Tumor cells harvested from tissue biopsied at the time of a patients cancer diagnosis are applied to a chip and then tested against various chemotherapy drugs so we can best predict what the best treatment is for that patient, before that patient gets the treatment, Atala said.

The cell therapy, 3D bioprinting and body-on-a-chip technologies are just a sampling of WFIRMs work, and we have a lot of things going on, Atala said.

Our mission is to bring these technologies to patients, to improve patients lives through regen med, he said. Our vision is to lead a global transformation from treatments to cures.

Beyond its own research, WFIRM has become a major influencer and resource in regenerative medicine nationally and globally.

It has over 400 research collaborations with scientists across the United States and around the world.

Specialized containers for cell processing.

For most of these collaborations, WFIRM is the one thats providing materials, reagents, cells and know-how, trying to disseminate this information to a global scale, Atala said.

WFIRM also helps prepare the next generation of regenerative medicine scientists through education and training programs for high school students, undergraduates, graduate students and post-doctoral fellows. It also sponsors conferences and workshops, provides content and materials for museum exhibits around the world and publishes textbooks.

The institute has spurred new initiatives and entities in Winston-Salem to advance regenerative medicine nationally and globally. This ecosystem, called the Regenerative Medicine Hub, includes the nonprofit RegenMed Development Organization (ReMDO), a research partner with WFIRM that sponsors several programs to advance the field nationwide, including the Regenerative Manufacturing Innovation Consortium and the Regenerative Medicine Manufacturing Society.

Startup Spotlight: RegeneratOR Test Bed in W-S aims to boost startups focusing on regenerative medicine

Through its RegeneratOR initiative, ReMDO sponsors three programs to support startup and growth companies in regenerative medicine:

These and other resources in the Regenerative Medicine Hub have attracted about30 bioscience companiesto Winston-Salems Innovation Quarter, ranging from local start-ups to multinational corporations.

The latest company to establish a presence at ReMDOs Innovation Accelerator is Houston-basedAxiom Space, developer of the first commercial space station that will supplement and eventually replace the International Space Station.

Axiom will partner with WFIRM and ReMDO to focus on innovations in regenerative medicine manufacturing in space. Research done on the new space station, in low orbit 250 miles above Earth, will be free from the constraints of gravity, providing potential benefits.

WFIRM and Winston-Salem have staked an early claim in a promising industry that appears destined for robust growth.

Various consultants reports predict the global market for regenerative medicine will expand at a compound annual growth rate ranging from 9 to 23% during this decade. By 2030 the market will be worth up to $150 billion, according to a report by Verified Market Research of Jersey City, N.J.

Driving that growth are an aging population battling chronic diseases, rising investments in regenerative medicine research, and advances in new technologies and therapies such as those being developed by WFIRM.

Regenerative medicine is an emerging field, Atala said. Were still trying to figure out what is the best next thing that we can do to advance these technologies.

Regenerative medicine – Wikipedia, the free encyclopedia

Posted: November 3, 2013 at 5:48 pm

Regenerative medicine is the "process of replacing or regenerating human cells, tissues or organs to restore or establish normal function".[1] This field holds the promise of regenerating damaged tissues and organs in the body by replacing damaged tissue and/or by stimulating the body's own repair mechanisms to heal previously irreparable tissues or organs.

Regenerative medicine also includes the possibility of growing tissues and organs in the laboratory and safely implant them when the body cannot heal itself This can potentially solves the problem of the shortage of organs available for donation, and the problem of organ transplant rejection if the organ's cells are derived from the patient's own tissue or cells.[2][3][4]

Widely attributed to having first been coined by William Haseltine (founder of Human Genome Sciences),[5] the term "Regenerative Medicine" was first found in a 1992 article on hospital administration by Leland Kaiser. Kaisers paper closes with a series of short paragraphs on future technologies that will impact hospitals. One such paragraph had Regenerative Medicine as a bold print title and went on to state, A new branch of medicine will develop that attempts to change the course of chronic disease and in many instances will regenerate tired and failing organ systems.[6][7]

Regenerative medicine refers to a group of biomedical approaches to clinical therapies that may involve the use of stem cells.[8] Examples include the injection of stem cells or progenitor cells (cell therapies); the induction of regeneration by biologically active molecules administered alone or as a secretion by infused cells (immunomodulation therapy); and transplantation of in vitro grown organs and tissues (Tissue engineering).[9][10]

A form of regenerative medicine that recently made it into clinical practice, is the use of heparan sulfate analogues on (chronic) wound healing. Heparan sulfate analogues replace degraded heparan sulfate at the wound site. They assist the damaged tissue to heal itself by repositioning growth factors and cytokines back into the damaged extracellular matrix.[11][12][13] For example, in abdominal wall reconstruction (like inguinal hernia repair), biologic meshes are being used with some success.

At the Wake Forest Institute for Regenerative Medicine, in North Carolina, Dr. Anthony Atala and his colleagues have successfully extracted muscle and bladder cells from several patients' bodies, cultivated these cells in petri dishes, and then layered the cells in three-dimensional molds that resembled the shapes of the bladders. Within weeks, the cells in the molds began functioning as regular bladders which were then implanted back into the patients' bodies.[14] The team is currently[when?] working on re-growing over 22 other different organs including the liver, heart, kidneys and testicles.[15]

From 1995 to 1998 Michael D. West, PhD, organized and managed the research between Geron Corporation and its academic collaborators James Thomson at the University of Wisconsin-Madison and John Gearhart of Johns Hopkins University that led to the first isolation of human embryonic stem and human embryonic germ cells.[16]

Dr. Stephen Badylak, a Research Professor in the Department of Surgery and director of Tissue Engineering at the McGowan Institute for Regenerative Medicine at the University of Pittsburgh, developed a process for scraping cells from the lining of a pig's bladder, decellularizing (removing cells to leave a clean extracellular structure) the tissue and then drying it to become a sheet or a powder. This cellular matrix powder was used to regrow the finger of Lee Spievak, who had severed half an inch of his finger after getting it caught in a propeller of a model plane.[17][18][19][dubious discuss] As of 2011, this new technology is being employed by the military to U.S. war veterans in Texas, as well as to some civilian patients. Nicknamed "pixie-dust," the powdered extracellular matrix is being used success to regenerate tissue lost and damaged due to traumatic injuries.

In June 2008, at the Hospital Clnic de Barcelona, Professor Paolo Macchiarini and his team, of the University of Barcelona, performed the first tissue engineered trachea (wind pipe) transplantation. Adult stem cells were extracted from the patient's bone marrow, grown into a large population, and matured into cartilage cells, or chondrocytes, using an adaptive method originally devised for treating osteoarthritis. The team then seeded the newly grown chondrocytes, as well as epithileal cells, into a decellularised (free of donor cells) tracheal segment that was donated from a 51 year old transplant donor who had died of cerebral hemorrhage. After four days of seeding, the graft was used to replace the patient's left main bronchus. After one month, a biopsy elicited local bleeding, indicating that the blood vessels had already grown back successfully.[20][21]

In 2009 the SENS Foundation was launched, with its stated aim as "the application of regenerative medicine defined to include the repair of living cells and extracellular material in situ to the diseases and disabilities of ageing." [22]

BACKGROUND: According to the U.S. Department of Health and Human Services, regenerative medicine is the next evolution of medical treatments. Regenerative medicine offers the potential for the body to heal itself. Scientists at the Wake Forest Institute for Regenerative Medicine in Winston-Salem, N.C., were the first in the world to engineer lab-grown organs that were successfully implanted into humans. Now, the team of researchers is working to engineer more than 30 different replacement tissues and organs to develop cell therapies with the goal of curing a variety of diseases.

LAB-GROWN URETHRAS: Researchers from Wake Forest were the first in the world to use patients own cells to build tailor-made urine tubes in the lab and successfully replace damaged tissue in five boys in Mexico. The boys were unable to urinate due to a pelvic injury. After receiving the lab-grown urethras, all the boys continue to do well with normal or near-normal urinary flow. The urethras were grown on biodegradable mesh scaffolds made of a polyester compound. The scaffolds were seeded with cells taken from the patients own bladders and incubated in the lab for four to seven weeks. They were then used to repair damaged segments of the boys urethras. For us, really, our goal here at the Institute is really to try to complete technologies that we can get to patients to make their lives better, so anytime that were able to do that, improve the quality of patients lives, we feel like thats part of our mission, Anthony Atala, M.D., Director, Wake Forest Institute for Regenerative Medicine, told Ivanhoe.

GROWING EARS: Scientists are working on printing ears in the lab. What we can do is we can take any three dimensional image of an ear, and it can be put into the computer, and that will generate an image within the printer that then prints that specific three dimensional structure, John Jackson, Ph.D., Associate Professor, Wake Forest Institute for Regenerative Medicine, told Ivanhoe. Right now, implants that are commercially-available are hard and rigid. They also cause problems with erosion through the skin. The new, tailor-made ears are flexible and patient-specific. In animal studies, the lab-grown ears have been shown to cause less erosion. The next step is to print the ears for use in humans. To be able to take a structure, generate a 3D implant and have that as a potential treatment for a patient who has lost an ear, thats very exciting, Dr. Jackson told Ivanhoe.

ENGINEERING MUSCLE: Researchers are also looking to see if they can engineer tissue that resembles muscle to repair small injuries in the body. They take biopsies from skeletal muscles and culture out the stem cells from the muscle. They then seed the cells onto a scaffold and condition the scaffold and a bioreactor to exercise muscle in-vitro. Then, they use that construct as an implant to accelerate regeneration and repair of injured muscle in the body. Scientists have been studying the engineered muscle in animals, and the next step is to try it in humans. For me, personally, its fantastic because you dont often get an opportunity to do research thats not only compelling but that can result in therapies that can help people on a daily basis and really improve their quality of life, George Christ, Ph.D., Professor of Regenerative Medicine, Wake Forest Institute for Regenerative Medicine, told Ivanhoe.
