Sanford Health a history of innovating and leading the way in new research.

Something that grabbed the attention of the NFL Alumni Association.

The NFL Alumni Association is a non-profit that looks to support retired NFL athletes and cheerleaders after their initial careers are over.

Because of the strenuous activity put on their bodies, many athletes walk away from the sport with nagging injuries without the option for care. This has led the NFL Alumni to seek out innovators in the world of health care.

Recently, Dr. David Pearce, Sanford Health president for innovation, research and World Clinic, spoke on regenerative medicine at a congressional briefing. His expertise prompted Kyle Richardson and Billy Davis, co-directors of health care initiatives for the NFL Alumni Association, to inquire about regenerative medicine and how it may serve retired athletes.

As Dr. Pearce told Sanford Health News, its a complicated term, but regenerative medicine is essentially about healing. Dr. Pearce explains that regenerative healing takes something from your own body to heal a wound or an injury.

Im going to give you an example: if you cut yourself right now, it heals, right? The components within your body have the ability to heal an injury, such as a cut. If we twist our ankle and we get swelling, our body reacts and heals that injury. Regenerative medicine is about accelerating that healing so, taking a component of your body, and accelerating that healing and making it better.

Not only for retired athletes, this form of therapy could benefit everyone as they age.

As we get older, we start to deteriorate. So, we can harness our own body to maybe take some of those components that would be used to fix an injury to actually slow down the aging process and the wear and tear on joints, partiucularly in orthopedics.

Thats one of the highlighted areas that we are studying right now. As your knees grind away and you get arthritis, regenerative medicine is about taking some of those healing components to help regenerate and slow down that process, to heal those aches and pains, said Dr. Pearce.

Tiffany Facile is a research development partner at Sanford Health, and soon-to-be director of regenerative medicine at Sanford Health.

She says its imperative this medicine develops through the science of clinical trials.

Some common misconceptions are that regenerative medicine therapies are risky. There is some risk to procedures when using autologous or your own cells, but studies that are currently running should reduce the safety concerns.

Dr. Pearce echos Facile, warning of bad actors who offer products which have no regenerative capacity.

He says theres also a misconception associated with these therapies because theyre not approved by the FDA. However, Sanford Healths clinical trials have been approved.

What were doing at Sanford, is were taking those components of the body, working with the FDA and saying, its safe to do this. Our early work in a clinical study has demonstrated safety and efficacy with rotator cuff injuries. Were having remarkable results in terms of treating some of these injuries.

Another misconception revolves around stem cells. Both Facile and Dr. Pearce say regenerative medicine has not yet determined if stem cells in your body have the ability to signal other cells for repair.

We hear about embryonic stem cells and fetal stem cells; we dont do anything with that. First of all, its not very ethical. Secondly, theres no science to show that they can have regenerative capabilities, said Dr. Pearce.

Dr. Pearce says regenerative medicine can be used to heal nagging injuries, whether its for athletes or not.

Right now were taking cells from around the fat of your abdomen region, which is rich in a type of stem cell called adipose derived regenerative cells, and were relocating them to help heal rotator cuff tears, help to heal osteoarthritis in the knee, elbow, wrist, ankle, and hip, he said.

Dr. Pearce says theyre doing this research, under the auspices of what we call a clinical trial, and where we follow patients to hopefully demonstrate safety and efficacy.

Because of the misconceptions surrounding this form of medicine, we have to do this right, because its not a regulated industry just yet. The food and drug administration oversees what were doing with respect to that.

We know that we can help heal damaged heart cells. We know we can help healing cells that have been damaged by a stroke. Were already taking the next step in working on those protocols where we can do some trials and look to see if we can heal other injuries in the body. These cells have the ability to heal anything in the body, if directed in the right way, said Dr. Pearce.

Dr. Pearce says Sanford Health is the first health system in the nation to get approval for the use of regenerative medicine in treating orthopedic injuries.

Were hoping to be a leader not just in the Midwest, were hoping to be a leader nationally, where we can teach other health systems how to administer these treatments by either going there and training people, or us becoming really a hub for that.

As for the future of regenerative medicine, Dr. Pearce says it could have an impact in how quickly athletes recover from injuries.

I think for athletes that return to play, this will have a huge impact in terms of how we can help people turn around. More importantly, as they retire, we know theres a lot of grinding and wear and tear on their bodies. Well be able to manage that much more appropriately, said Dr. Pearce.

This form of medicine can also help non-athletes manage any nagging aches and pains.

For those whove got some aches and pains here and there, well be able to use this to really alleviate some of the pain and aches we have, and manage that much better.

Regenerative medicine, the application of treatments developed to replace tissues damaged by injury or disease. These treatments may involve the use of biochemical techniques to induce tissue regeneration directly at the site of damage or the use of transplantation techniques employing differentiated cells or stem cells, either alone or as part of a bioartificial tissue. Bioartificial tissues are made by seeding cells onto natural or biomimetic scaffolds (see tissue engineering). Natural scaffolds are the total extracellular matrixes (ECMs) of decellularized tissues or organs. In contrast, biomimetic scaffolds may be composed of natural materials, such as collagen or proteoglycans (proteins with long chains of carbohydrate), or built from artificial materials, such as metals, ceramics, or polyester polymers. Cells used for transplants and bioartificial tissues are almost always autogeneic (self) to avoid rejection by the patients immune system. The use of allogeneic (nonself) cells carries a high risk of immune rejection and therefore requires tissue matching between donor and recipient and involves the administration of immunosuppressive drugs.

A variety of autogeneic and allogeneic cell and bioartificial tissue transplantations have been performed. Examples of autogeneic transplants using differentiated cells include blood transfusion with frozen stores of the patients own blood and repair of the articular cartilage of the knee with the patients own articular chondrocytes (cartilage cells) that have been expanded in vitro (amplified in number using cell culture techniques in a laboratory). An example of a tissue that has been generated for autogeneic transplant is the human mandible (lower jaw). Functional bioartificial mandibles are made by seeding autogeneic bone marrow cells onto a titanium mesh scaffold loaded with bovine bone matrix, a type of extracellular matrix that has proved valuable in regenerative medicine for its ability to promote cell adhesion and proliferation in transplantable bone tissues. Functional bioartificial bladders also have been successfully implanted into patients. Bioartificial bladders are made by seeding a biodegradable polyester scaffold with autogeneic urinary epithelial cells and smooth muscle cells.

Another example of a tissue used successfully in an autogeneic transplant is a bioartificial bronchus, which was generated to replace damaged tissue in a patient affected by tuberculosis. The bioartificial bronchus was constructed from an ECM scaffold of a section of bronchial tissue taken from a donor cadaver. Differentiated epithelial cells isolated from the patient and chondrocytes derived from mesenchymal stem cells collected from the patients bone marrow were seeded onto the scaffold.

There are few clinical examples of allogeneic cell and bioartificial tissue transplants. The two most common allogeneic transplants are blood-group-matched blood transfusion and bone marrow transplant. Allogeneic bone marrow transplants are often performed following high-dose chemotherapy, which is used to destroy all the cells in the hematopoietic system in order to ensure that all cancer-causing cells are killed. (The hematopoietic system is contained within the bone marrow and is responsible for generating all the cells of the blood and immune system.) This type of bone marrow transplant is associated with a high risk of graft-versus-host disease, in which the donor marrow cells attack the recipients tissues. Another type of allogeneic transplant involves the islets of Langerhans, which contain the insulin-producing cells of the body. This type of tissue can be transplanted from cadavers to patients with diabetes mellitus, but recipients require immunosuppression therapy to survive.

Cell transplant experiments with paralyzed mice, pigs, and nonhuman primates demonstrated that Schwann cells (the myelin-producing cells that insulate nerve axons) injected into acutely injured spinal cord tissue could restore about 70 percent of the tissues functional capacity, thereby partially reversing paralysis.

Studies on experimental animals are aimed at understanding ways in which autogeneic or allogeneic adult stem cells can be used to regenerate damaged cardiovascular, neural, and musculoskeletal tissues in humans. Among adult stem cells that have shown promise in this area are satellite cells, which occur in skeletal muscle fibres in animals and humans. When injected into mice affected by dystrophy, a condition characterized by the progressive degeneration of muscle tissue, satellite cells stimulate the regeneration of normal muscle fibres. Ulcerative colitis in mice was treated successfully with intestinal organoids (organlike tissues) derived from adult stem cells of the large intestine. When introduced into the colon, the organoids attached to damaged tissue and generated a normal-appearing intestinal lining.

In many cases, however, adult stem cells such as satellite cells have not been easily harvested from their native tissues, and they have been difficult to culture in the laboratory. In contrast, embryonic stem cells (ESCs) can be harvested once and cultured indefinitely. Moreover, ESCs are pluripotent, meaning that they can be directed to differentiate into any cell type, which makes them an ideal cell source for regenerative medicine.

Studies of animal ESC derivatives have demonstrated that these cells are capable of regenerating tissues of the central nervous system, heart, skeletal muscle, and pancreas. Derivatives of human ESCs used in animal models have produced similar results. For example, cardiac stem cells from heart-failure patients were engineered to express a protein (Pim-1) that promotes cell survival and proliferation. When these cells were injected into mice that had experienced myocardial infarction (heart attack), the cells were found to enhance the repair of injured heart muscle tissue. Likewise, heart muscle cells (cardiomyocytes) derived from human ESCs improved the function of injured heart muscle tissue in guinea pigs.

Derivatives of human ESCs are likely to produce similar results in humans, although these cells have not been used clinically and could be subject to immune rejection by recipients. The question of immune rejection was bypassed by the discovery in 2007 that adult somatic cells (e.g., skin and liver cells) can be converted to ESCs. This is accomplished by transfecting (infecting) the adult cells with viral vectors carrying genes that encode transcription factor proteins capable of reprogramming the adult cells into pluripotent stem cells. Examples of these factors include Oct-4 (octamer 4), Sox-2 (sex-determining region Y box 2), Klf-4 (Kruppel-like factor 4), and Nanog. Reprogrammed adult cells, known as induced pluripotent stem (iPS) cells, are potential autogeneic sources for cell transplantation and bioartificial tissue construction. Such cells have since been created from the skin cells of patients suffering from amyotrophic lateral sclerosis (ALS) and Alzheimer disease and have been used as human models for the exploration of disease mechanisms and the screening of potential new drugs. In one such model, neurons derived from human iPS cells were shown to promote recovery of stroke-damaged brain tissue in mice and rats, and, in another, cardiomyocytes derived from human iPS cells successfully integrated into damaged heart tissue following their injection into rat hearts. These successes indicated that iPS cells could serve as a cell source for tissue regeneration or bioartificial tissue construction.

Newswise Green manufacturing is becoming an increasingly critical process across industries, propelled by a growing awareness of the negative environmental and health impacts associated with traditional practices. In the biomaterials industry, electrospinning is a universal fabrication method used around the world to produce nano- to microscale fibrous meshes that closely resemble native tissue architecture. The process, however, has traditionally used solvents that not only are environmentally hazardous but also pose a significant barrier to industrial scale-up, clinical translation, and, ultimately, widespread use.

Researchers atColumbia Engineeringreport that they have developed a "green electrospinning" process that addresses many of the challenges to scaling up this fabrication method, from managing the environmental risks of volatile solvent storage and disposal at large volumes to meeting health and safety standards during both fabrication and implementation. The teams newstudy, published June 28, 2021, by Biofabrication, details how they have modernized the nanofiber fabrication of widely utilized biological and synthetic polymers (e.g. poly--hydroxyesters, collagen), polymer blends, and polymer-ceramic composites.

The study also underscores the superiority of green manufacturing. The groups green fibers exhibited exceptional mechanical properties and preserved growth factor bioactivity relative to traditional fiber counterparts, which is essential for drug delivery and tissue engineering applications.

Regenerative medicine is a $156 billion global industry, one that is growing exponentially. The team of researchers, led byHelen H. Lu, Percy K. and Vida L.W. Hudson Professor ofBiomedical Engineering, wanted to address the challenge of establishing scalable green manufacturing practices for biomimetic biomaterials and scaffolds used in regenerative medicine.

We think this is a paradigm shift in biofabrication, and will accelerate the translation of scalable biomaterials and biomimetic scaffolds for tissue engineering and regenerative medicine, said Lu, a leader in research on tissue interfaces, particularly the design of biomaterials and therapeutic strategies for recreating the bodys natural synchrony between tissues. Green electrospinning not only preserves the composition, chemistry, architecture, and biocompatibility of traditionally electrospun fibers, but it also improves their mechanical properties by doubling the ductility of traditional fibers without compromising yield or ultimate tensile strength. Our work provides both a more biocompatible and sustainable solution for scalable nanomaterial fabrication.

The team, which included several BME doctoral students from Lus group, Christopher Mosher PhD20 and Philip Brudnicki, as well as Theanne Schiros, an expert in eco-conscious textile synthesis who is also a research scientist at Columbia MRSEC and assistant professor at FIT, applied sustainability principles to biomaterial production, and developed a green electrospinning process by systematically testing what the FDA considers as biologically benign solvents (Q3C Class 3).

They identified acetic acid as a green solvent that exhibits low ecological impact (Sustainable Minds Life Cycle Assessment) and supports a stable electrospinning jet under routine fabrication conditions. By tuning electrospinning parameters, such as needle-plate distance and flow rate, the researchers were able to ameliorate the fabrication of research and industry-standard biomedical polymers, cutting the detrimental manufacturing impacts of the electrospinning process by three to six times.

Green electrospun materials can be used in a broad range of applications. Lus team is currently working on further innovating these materials for orthopaedic and dental applications, and expanding this eco-conscious fabrication process for scalable production of regenerative materials.

"Biofabrication has been referred to as the fourth industrial revolution' following steam engines, electrical power, and the digital age for automating mass production, noted Mosher, the studys first author. This work is an important step towards developing sustainable practices in the next generation of biomaterials manufacturing, which has become paramount amidst the global climate crisis."

Scientists from the USC Stem Cell laboratory of Neil Segil have identified a natural barrier to the regeneration of the inner ears sensory cells, which are lost in hearing and balance disorders. Overcoming this barrier may be a first step in returning inner ear cells to a newborn-like state thats primed for regeneration, as described in a new study published inDevelopmental Cell.

Permanent hearing loss affects more than 60 percent of the population that reaches retirement age, said Segil, who is a Professor in the Department of Stem Cell Biology and Regenerative Medicine, and the USC Tina and Rick Caruso Department of Otolaryngology Head and Neck Surgery. Our study suggests new gene engineering approaches that could be used to channel some of the same regenerative capability present in embryonic inner ear cells.

In the inner ear, the hearing organ, which is the cochlea, contains two major types of sensory cells: hair cells that have hair-like cellular projections that receive sound vibrations; and so-called supporting cells that play important structural and functional roles.

When the delicate hair cells incur damage from loud noises, certain prescription drugs, or other harmful agents, the resulting hearing loss is permanent in older mammals. However, for the first few days of life, lab mice retain an ability for supporting cells to transform into hair cells through a process known as transdifferentiation, allowing recovery from hearing loss. By one week of age, mice lose this regenerative capacityalso lost in humans, probably before birth.

Based on these observations, postdoctoral scholar Litao Tao, PhD, graduate student Haoze (Vincent) Yu, and their colleagues took a closer look at neonatal changes that cause supporting cells to lose their potential for transdifferentiation.

In supporting cells, the hundreds of genes that instruct transdifferentiation into hair cells are normally turned off. To turn genes on and off, the body relies on activating and repressive molecules that decorate the proteins known as histones.In response to these decorations known as epigenetic modifications, the histone proteins wrap the DNA into each cell nucleus, controlling which genes are turned on by being loosely wrapped and accessible, and which are turned off by being tightly wrapped and inaccessible. In this way, epigenetic modifications regulate gene activity and control the emergent properties of the genome.

In the supporting cells of the newborn mouse cochlea, the scientists found that hair cell genes were suppressed by both the lack of an activating molecule, H3K27ac, and the presence of the repressive molecule, H3K27me3.However, at the same time, in the newborn mouse supporting cells, the hair cell genes were kept primed to activate by the presence of yet a different histone decoration, H3K4me1.During transdifferentiation of a supporting cell to a hair cell, the presence of H3K4me1 is crucial to activate the correct genes for hair cell development.

Unfortunately with age, the supporting cells of the cochlea gradually lost H3K4me1, causing them to exit the primed state. However, if the scientists added a drug to prevent the loss of H3K4me1, the supporting cells remained temporarily primed for transdifferentiation. Likewise, supporting cells from the vestibular system, which naturally maintained H3K4me1, were still primed for transdifferentiation into adulthood.

Our study raises the possibility of using therapeutic drugs, gene editing, or other strategies to make epigenetic modifications that tap into the latent regenerative capacity of inner ear cells as a way to restore hearing, said Segil. Similar epigenetic modifications may also prove useful in other non-regenerating tissues, such as the retina, kidney, lung, and heart.

The next major development in Israels life science industry is coming from a microscopic source. Biotech based on the tiny building blocks of life is a sector positioned to unlock new discoveries and drive economic growth in the future.

Although the Start-Up Nation is a well-deserved nickname, I believe Biotech Nation will soon be a better fit.

Biotechnology accounts for more than one-quarter of the countrys life science scene. There are currently 468 active biotech firms, employing thousands of high-skilled workers.

cnxps.cmd.push(function () { cnxps({ playerId: '36af7c51-0caf-4741-9824-2c941fc6c17b' }).render('4c4d856e0e6f4e3d808bbc1715e132f6'); });

And the industry is evolving in new directions.

We are amid a bio-convergence revolution. This means that biology research increasingly leverages multidisciplinary talent, such as computer engineers, big data scientists, artificial intelligence and advanced manufacturing.

The results are broader capabilities, bolder aspirations and bigger breakthroughs. IATI views bio-convergence as the next major economic growth engine for Israel.

The government is also betting on bio-convergence.

Since the Israel Innovation Authority launched CRISPR-IL, a consortium that combines artificial intelligence and CRISPR capabilities to develop genome editing tools, our leading scientists and biotech companies are joining forces to find new treatments and cures.

I am proud Pluristem is teaming up with this initiative. Partnerships like CRISPR-IL are setting an exemplary model that will lead to many more industry disruptions.

It should come as no surprise that when compared to the rest of the world, Israel spends the highest percentage of GDP on research and development. We already have 300 research groups and 30 academic centers working on bio-convergence R&D.

I have observed that in the wake of the COVID-19 pandemic, interest in regenerative medicine research skyrocketed. At Pluristem, we are developing cell-based therapeutics derived from donated placentas to potentially treat hematological deficiencies, radiation exposure, and muscle injuries related to hip fracture surgery.

Now, there are more 1,000 regenerative medicine trials active around the world. The Alliance for Regenerative Medicine reports that about 85% are in Phase I or II studies. Pluristem has one of the few in Phase III: our PLX-PAD product candidate to support muscle regeneration following hip fracture surgery may be the first approved treatment of its kind.

Early on, we knew that it would also be critical to have our own proprietary cell manufacturing technology that could be scalable from research to commercial use. So, we developed a three-dimensional micro-environment mimicking the conditions in the human body, which allows us to expand our placenta cells and transform them to cell therapy products. This result is only made possible by a cross section of talent from clinical and technology backgrounds, demonstrating the power of bio-convergence.

Its not a moment too soon. Most countries face demographic headwinds, such as aging and declining populations. Many developed nations are already experiencing these trends coupled with skyrocketing health care costs. The world will see a surge in demand for new treatments and ways to control healthcare spending.

The Israeli approach, leveraging out-of-the-box thinking, a spirit of innovation, and a long track record of breakthrough treatments, can convert these challenges into opportunities.

Technology is a force that brings people together, across professional fields, cultures, and borders. When advanced technology is paired with cutting edge medical research, we have the power to craft the future we want.

As IATI reports, our biotech sector is full of boundless opportunities. Israel is one of the greatest places in the world for biotech companies to thrive.

The writer is CEO and president of Pluristem. He is also a board member and former co-chairman of Israel Advanced Technology Industries, and served as CFO of Elbit Vision Systems.

Israel: The 'Start-Up Nation' is now the 'Biotech Nation' - opinion - The Jerusalem Post

CHICAGO (CBS) Its a treatment that could help keep COVID-19 patients off ventilators, and researchers at the University of Illinois Chicago are on the forefront of developing it.

CBS 2 Investigator Megan Hickey sat down exclusively with the scientist who made the discovery and is getting a $6 million grant to make it happen.

Its called VT-109 and it was created to prevent lung damage that plagues COVID 19 patients. Not only could it help keep patients from having to use a ventilator, it could help save lives.

Yulia Komarova has been working on this drug for years well before COVID-19 hit.

You have to be very persistent when you work in academia, especially on the drug development programs, Komarova said.

FULL INTERVIEW: Yulia Komarova Of UIC On A Treatment That Could Keep COVID Patients Off Ventilators

The UIC associate professor in the Department of Pharmacology and Regenerative Medicine said its been shown to prevent lung damage by tightening the barrier between the bloodstream and the lungs.

Help them to restore the lung function and the function of the other organs because everything depends on the lung function, Komarova said.

Not just prevent lung damage, but this drug has shown to restore lung function. Survival in the animals treated with VT-109, that otherwise would have likely died, was 80%.

Within the first few months of the pandemic, it became clear to Komarova and her team that the implications for human COVID-19 patients were worth investigating.

They applied for the grant in June 2020 and were just awarded $6 million from the Department of Defense.

The studies are very expensive because It involves good laboratory practice, Komarova said.

Theyre still at the beginning of a long road. But the grant is an honor for Komarova, who came to Chicago from Russia two decades ago to do this important work.

Its also an honor for her team at UIC, which is hoping theyll be able to make a significant dent in COVID-19 fatalities in the years to come.

We expect that we can save the majority of the patients, Komarova said.

Komarova hopes to apply for the FDAS new investigational drug program by July 2024, although shes hopeful it could happen before then.
