Health Beat: Stem cells: A weapon for Huntington's?

Posted: January 6, 2015 at 11:50 pm

SAN FRANCISCO -

Mike Hinshaw and Katie Jackson have been a couple since college, but they've known each other much longer.

"We've been together forever. I've actually known Mike since I was five years old," Jackson said.

A marriage and three kids later, they've been through good times and bad. The worst came nine years ago when Hinshaw found out he had Huntington's disease.

"My father had it. He died from it," Hinshaw explained.

Huntington's causes uncontrollable movements and mental decline. There's no cure.

"Unfortunately, it ends in death. It's a fatal disease," said Dr. Vicki Wheelock, neurologist, health sciences clinical professor of neurology and director of HDSA Center of Excellence at UC Davis.

Now, researchers are gearing up for a new trial in humans. Patients will have special bone marrow stem cells injected directly into their brains.

"We've engineered them to make a growth factor that's like a fertilizer for the neurons," said Dr. Jan Nolta, professor and director of the Institute for Regenerative Cures at UC Davis.

That growth factor, BDNF, restored healthy brain cells and reduced behavior deficits in mice. Researchers hope the stem cells will also be the answer to slowing the disease in humans.

New Rochelle, NY, January 6, 2015--Timothy Ray Brown, long known only as the "Berlin Patient" had HIV for 12 years before he became the first person in the world to be cured of the infection following a stem cell transplant in 2007. He recalls his many years of illness, a series of difficult decisions, and his long road to recovery in the first-person account, "I Am the Berlin Patient: A Personal Reflection," published in AIDS Research and Human Retroviruses, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers. The article is part of a special issue on HIV Cure Research and is available free on the AIDS Research and Human Retroviruses website.

Brown's Commentary describes the bold experiment of using a stem cell donor who was naturally resistant to HIV infection to treat the acute myeloid leukemia (AML) diagnosed 10 years after he became HIV-positive. The stem cell donor had a specific genetic mutation called CCR5 Delta 32 that can protect a person against HIV infection. The virus is not able to enter its target, the CD4 cells. After the stem cell transplant, Brown was able to stop all antiretroviral treatment and the HIV has not returned.

"This is the first time that we get to read this important story written by the man who lived it," says Thomas Hope, PhD, Editor-in-Chief of AIDS Research and Human Retroviruses and Professor of Cell and Molecular Biology at Northwestern University, Feinberg School of Medicine, Chicago, IL. "It is a unique opportunity to share in the human side of this transformative experience."

Circadian rhythms regulate skin stem cell metabolism and expansion, UCI study finds

Posted: January 6, 2015 at 11:44 pm

Body clock protects cells from metabolism-generated oxygen radical damage during division

Irvine, Calif., Jan. 6, 2015 -- UC Irvine scientists studying the role of circadian rhythms in skin stem cells found that this clock plays a key role in coordinating daily metabolic cycles and cell division.

Their research, which appears Jan. 6 in Cell Reports, shows for the first time how the body's intrinsic day-night cycles protect and nurture stem cell differentiation. Furthermore, this work offers novel insights into a mechanism whereby an out of synch circadian clock can contribute to accelerated skin aging and cancers.

Bogi Andersen, professor of biological chemistry and medicine, and Enrico Gratton, professor of biomedical engineering, focused their efforts on the epidermis, the outermost protective layer of the skin that is maintained and healed by long-lived stem cells.

While the role of the circadian clock in processes such as sleep, feeding behavior and metabolism linked to feeding and fasting are well known, much less is known about whether the circadian clock also regulates stem cell function.

The researchers used novel two-photon excitation and fluorescence lifetime imaging microscopy in Laboratory of Fluorescence Dynamics in UCI's Department of Biomedical Engineering to make sensitive and quantitative measurements of the metabolic state of single cells within the native microenvironment of living tissue.

They discovered that the circadian clock regulates one form of intermediary metabolism in these stem cells, referred to as oxidative phosphorylation. This type of metabolism creates oxygen radicals that can damage DNA and other components of the cell. In fact, one theory of aging posits that aging is caused by the accumulative damage from metabolism-generated oxygen radicals in stem cells.

The Andersen-Gratton study also revealed that the circadian clock within stem cells shifts the timing of cell division such that the stages of the cell division cycle that are most sensitive to DNA damage are avoided during times of maximum oxidative phosphorylation.

Other studies in animals have linked aging to disruption of circadian rhythms, and Andersen said that accelerated aging could be caused by asynchrony in the metabolism and cell proliferation cycles in stem cells.

"Our studies were conducted in mice, but the greater implication of the work relates to the fact that circadian disruption is very common in modern society, and one consequence of such disruption could be abnormal function of stem cells and accelerated aging," he said.

Gamida Cell treatment granted orphan drug status

Posted: January 6, 2015 at 11:44 pm

Stem cell therapy developer Gamida Cell has been awarded orphan drug status by the US Food and Drug Administration (FDA) and European Medicines Agency (EMA) for leukemia treatment NiCord. The investigational drug treats acute lymphoblastic leukemia (ALL), acute myeloid leukemia (AML), Hodgkin lymphoma and myelodysplastic syndrome (MDS). Gamida Cell intends to file for NiCord orphan drug status with the EMA for other indications as well.

Gamida Cell president and CEO Dr. Yael Margolin said, "Receipt of orphan drug status for NiCord in the US and Europe advances Gamida Cell's commercialization plans a major step further, as both afford significant advantages. We very much appreciate the positive feedback and support of the FDA and EMA and look forward to continuing what has been a very positive dialogue with these important agencies."

The FDA and EMA grant an orphan drug designation to promote the development of products that demonstrate promise for the treatment of rare diseases or conditions. Orphan drug designation provides for various regulatory and economic benefits, including seven years of market exclusivity in the US and 10 years in the EU.

NiCord is derived from a single cord blood unit, which has been expanded in culture and enriched with stem cells using Gamida Cell's proprietary NAM technology. It is currently being tested in a Phase I/II study as an investigational therapeutic treatment for hematological malignancies such as leukemia and lymphoma. In this study, NiCord is being used as the sole stem cell source.

Cord Blood Banking Leader, Cryo-Cell International, Continues to Support the Advancement of Regenerative Medicine

Posted: January 6, 2015 at 11:44 pm

Tampa, FL (PRWEB) January 06, 2015

One million Americans experience acute myocardial infarctions, commonly known as a heart attack, each year and of those, approximately 300,000 to 500,000 individuals develop heart failure. A heart attack occurs when blood stops flowing properly to a part of the heart and the heart muscle is injured and can die because it is not receiving enough oxygen.

Cryo-Cell International has agreed to provide the Center with cord blood collections that have previously been donated to Cryo-Cell International by parents and designated for research use to advance regenerative medicine. These cord blood collections will allow the Centers scientists to continue to investigate the mechanisms whereby stem cells can be beneficial in limiting damage from heart attacks. A team at the Center, led by researcher and cardiology specialist, Robert J. Henning, M.D., has demonstrated in research animals that stem cells obtained from human umbilical cord blood can release a large number of biologically active growth factors and anti-inflammatory chemicals that can limit the substantial heart inflammation, cell injury and cell destruction that occurs with acute heart attacks, significantly reducing the effects of heart attacks, even when administered up to 24 hours after the heart attack.

We are making good progress in our studies thanks to the cord blood stem cells contributed by Cryo-Cell International, reports Henning.

Cryo-Cell International and others have demonstrated that human umbilical cord blood stem cells can be preserved for more than 20 years without loss of cell viability or potency. Consequently, parents who have the foresight to use cord blood banking services upon their babys birth can potentially use these cord blood stem cells years later to provide a regenerative treatment for a family member if an acute heart attack occurs. The Centers scientists hope to bring umbilical cord blood stem cell therapy to the treatment of patients who have experienced heart attacks within the next five years.

Heart disease is still the number one leading cause of death in the United States. We feel very fortunate that we can provide a valuable and consistent source of cord blood banked stem cells to the Center for Cardiovascular Research, said David Portnoy, Chairman and Co-CEO of Cryo-Cell International.

About Cryo-Cell International

Founded in 1989, Cryo-Cell International, Inc. is the world's first and most highly accredited private cord blood bank. More than 500,000 parents from 87 countries trust Cryo-Cell International to preserve their family members' stem cells.

Regenerative medicine program set for Thursday in Vail

Posted: January 5, 2015 at 7:45 pm

VAIL Regenerative medicine, including stem cells, seems miraculous, so of course the demand far outstrips the pace at which research can create a supply.

The medical and scientific community are doing everything they can, but the demand for them always outpaces their availability. Research take a long time, said Dr. David Karli with the Steadman Clinic.

The Vail Symposium is gathering three experts in the field to discuss whats available, what the limitations are, and whats in the pipeline. The program, The Patient Consumer: Navigating the Waters of Regenerative Medicine, takes place Thursday at Vail Mountain School. Along with Karli, Dr. Chris Centeno and Dr. Maynard Howe also are on the panel.

OUTSTANDING PANEL

The Vail Symposium had its first stem cell program last year, outlining the progress of stem cell science, said the Symposiums Dale Mosier. It was so fascinationg they decided to do one every year, Mosier said.

This years presenters have been doing stem cell/regenerative medicine for many years and they have the successful history in different applications many patients to make for an outstanding panel, Mosier said.

Thursdays panel will be moderated by Rohn Robbins.

What is it?

Regenerative medicine is anything that would facilitate regenerative healing in the body, Karli said.

It works best for body parts that dont heal well on their own because they lack a good blood supply. If you pull a muscle, it heals because blood carries healing properties to the injury, Karli explained.

The Irvine Stem Cell Treatment Center, along with sister affiliates, the Miami Stem Cell Treatment Center and the Manhattan Regenerative Medicine Medical Group, abide by investigational protocols using adult adipose derived stem cells (ADSCs) which can be deployed to improve patients quality of life for a number of chronic, degenerative and inflammatory conditions and diseases. ADSCs are taken from the patients own adipose (fat) tissue (found within a cellular mixture called stromal vascular fraction (SVF)). ADSCs are exceptionally abundant in adipose tissue. The adipose tissue is obtained from the patient during a 15 minute mini-liposuction performed under local anesthesia in the doctors office. SVF is a protein-rich solution containing mononuclear cell lines (predominantly adult autologous mesenchymal stem cells), macrophage cells, endothelial cells, red blood cells, and important Growth Factors that facilitate the stem cell process and promote their activity.

ADSCs are the body's natural healing cells - they are recruited by chemical signals emitted by damaged tissues to repair and regenerate the bodys injured cells. The Irvine Stem Cell Treatment Center only uses Adult Autologous Stem Cells from a persons own fat No embryonic stem cells are used. Current areas of study include: Emphysema, COPD, Asthma, Heart Failure, Parkinsons Disease, Stroke, Multiple Sclerosis, Lupus, Rheumatoid Arthritis, Crohns Disease, and degenerative orthopedic joint conditions. For more information, or if someone thinks they may be a candidate for one of the adult stem cell protocols offered by the Irvine Stem Cell Treatment Center, they may contact Dr. Gionis directly at (949) 679-3889, or see a complete list of the Centers study areas at: http://www.IrvineStemCellsUSA.com.

About the Irvine Stem Cell Treatment Center: The Irvine Stem Cell Treatment Center, along with sister affiliates, the Miami Stem Cell Treatment Center and the Manhattan Regenerative Medicine Medical Group, is an affiliate of the Cell Surgical Network (CSN); we are located in Irvine and Westlake, California. We provide care for people suffering from diseases that may be alleviated by access to adult stem cell based regenerative treatment. We utilize a fat transfer surgical technology to isolate and implant the patients own stem cells from a small quantity of fat harvested by a mini-liposuction on the same day. The investigational protocols utilized by the Irvine Stem Cell Treatment Center have been reviewed and approved by an IRB (Institutional Review Board) which is registered with the U.S. Department of Health, Office of Human Research Protection; and the study is registered with Clinicaltrials.gov, a service of the U.S. National Institutes of Health (NIH).

Posted: January 5, 2015 at 7:40 pm

Some people say that osteoarthritis, cartilage degradation, and chronic joint pains degenerative diseases associated with agingare conditions with no cure, but Dr. Charlie Poblete and Dr. Jae Pak say otherwise.

It is a new era of medicine, opens Dr. Jae Pak, one of Koreas premier orthopedic stem cell surgeons and a visiting expert consultant of the Stem Care Orthopedics Department under Aivee Institute (AI). He was recently in the country to shed light on stem cell therapy and how it offers more accessible treament options for patients suffering from degenerative orthopedic conditions.

Dr. Pak was joined by Dr. Charlie Poblete, one of the countrys leading orthopedic surgeon who has a special interest on regenerative medicine and stem cells. Incidentally, Dr. Poblete is the head of the Stem Care Orthopedic Department of AI. Stem cells are not really part of alternative medicine. Its part of a modern medicine because we are talking about the biochemistry that goes on in the body with stem cell treatment, Dr. Charlie relates while adding, the good thing about medicine nowadays is its starting to look at the molecular aspect of the body, the molecular and cellular side of medicine.

Over the years, stem cell therapy has been touted as one procedure that can heal multitude of bone, cartilage, and joint ailments. Stem cells are the bodys natural healing cells. They are recruited by chemical signals emitted by damaged tissues to repair and regenerate the damaged cells. Stem cells derived from an individuals tissues may well be the next major development in medicine. In the right environment, these stem cells can change into bone, cartilage, muscle, fat, collagen, neural tissue, blood vessels, and even some organs. Stem cells may also effect healing by secreting special chemical messengers that repair damaged tissue.

There are many clinical conditions that benefits from stem cell therapy: heart attack patients have shown quicker healing period, improved condition for patients with multiple sclerosis, muscular dystrophy, Parkinsons disease, ALS, and stroke. Stem cells may also be effective in the treatment of macular degeneration, Crohns disease, and numerous pulmonary conditions. Also, stem cells are now used for patients with kidney failure and in the treatment of critical limb ischemia.

Stem Cell therapy is a simple procedure. Fat is aspirated from the tummy or the thighs, and then we separate the stem cells from them. It is then activated and injected into joints to restore and regenerate, explains Dr. Jae.

Stem Care by The Aivee Group is the countrys pioneer in advanced Autologous Stem Cell Therapy with an esteemed orthopedic team of doctors and surgeons regarded with international qualifications. The institute, with its CEO and medical director Dr. Z. Teo, together with his wife dermatologist Dr. Aivee Teo, now features a stronger multifaceted protocol in treating orthopedic ailments with a faster rate of positive patient response. They are also adept in complimentary therapies to further intensify the restorative powers of stem cells through the effective use of Growth Factors, Shockwave, Radio Frequency, and Electro Magnetic Therapies. 4033245, 4031982, 09209665613, 09175210222. http://www.stemcareinstitute.com

Scientists Develop Pioneering Method to Define Stages of Stem Cell Reprogramming

Available for logged-in reporters only

Newswise In a groundbreaking study that provides scientists with a critical new understanding of stem cell development and its role in disease, UCLA researchers at the Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research led by Dr. Kathrin Plath, professor of biological chemistry, have established a first-of-its-kind methodology that defines the unique stages by which specialized cells are reprogrammed into stem cells that resemble those found in the embryo.

The study was published online ahead of print in the journal Cell.

Induced pluripotent stem cells (known as iPSCs) are similar to human embryonic stem cells in that both cell types have the unique ability to self-renew and have the flexibility to become any cell in the human body. iPSC cells, however, are generated by reprogramming skin or blood cells and do not require an embryo.

Reprogramming is a long process (about one to two weeks) and largely inefficient, with typically less than one percent of the primary skin or blood cells successfully completing the journey to becoming an iPSC. The exact stages a cell goes through during the reprogramming process are also not well understood. This knowledge is important, as iPSCs hold great promise in the field of regenerative medicine, as they can provide a single source of patient-specific cells to replace those lost to injury or disease. They can also be used to create novel disease models from which new drugs and therapies can be developed.

This research has broad impact, because by deepening our understanding of cell reprogramming we have the potential to improve disease modeling and the generation of better sources of patient-specific specialized cells suitable for replacement therapy, said Plath. This can ultimately benefit patients with new and better treatments for a wide range of diseases.

Drs. Vincent Pasque and Jason Tchieu, postdoctoral fellows in the lab of Dr. Plath and co-first authors of the study, developed a roadmap of the reprogramming process using detailed time-course analyses. They induced the reprogramming of skin cells into iPSC, then observed and analyzed on a daily basis or every other day the process of transformation at the single-cell level. The data were collected and recorded over a period of up to two weeks.

Plaths team found that the changes that happen in cells during reprogramming occur in a sequential stage-by-stage manner, and that importantly, the stages were the same across all the different reprogramming systems and different cell types analyzed.

The exact stage of reprogramming of any cell can now be determined, said Pasque. This study signals a big change in thinking, because it provides simple and efficient tools for scientists to study stem cell creation in a stage-by-stage manner. Most studies to date ignore the stages of reprogramming, but we can now seek to better understand the entire process on both a macro and micro level.
