Stem cell researchers at the Blond McIndoe Laboratory, University of Manchester, UK, led by Dr Adam Reid, present a review of the current literature on the suitability of adipose-derived stem cells in peripheral nerve repair.

Injuries to peripheral nerves are common and cause life-changing problems for patients alongside high social and health care costs for society. Current clinical treatment relies on sacrificing a nerve from elsewhere in the body to provide a nerve graft at the injury site, but much work has been done to develop a bioengineered nerve graft that would not require this sacrifice. Stem cells are prime candidates as accelerators of regeneration in these nerve grafts.

This prospect, reported in Neural Regeneration Research (Vol. 9, No.14, 2014), presents the current literature on the potential of adipose-derived stem cells as tools to improve nerve regeneration through bioengineered nerve grafts. "Adipose-derived stem cells have the potential to stimulate improved nerve regeneration", stated the authors. "Their incorporation into bioengineered nerve graft treatments could revolutionize the current clinical approach to peripheral nerve repair".

San Diegan joins state stem cell agency

David Higgins of San Diego, a biotech veteran and an advocate for people with Parkinson's disease, has joined the governing board of California's stem cell agency.

Higgins, who has Parkinson's himself, replaces Joan Samuelson on the Independent Citizens' Oversight Committee that governs the California Institute for Regenerative Medicine. The institute is distributing a total of $3 billion in state bond money in a years-long bid to turn stem cell research into therapies.

Higgins' appointment was announced this week. He was chosen by state Controller John Chiang to take the patient advocate position for Parkinson's disease. Higgins is president of the board for the Parkinson's Association of San Diego.

He holds a Ph.D. in molecular biology and genetics from the University of Rochester, and has worked at the biotech companies Invitrogen, Chiron and Idun Pharmaceuticals. Higgins now serves as an adviser to iDiverse, a gene technology company in Del Mar.

In addition, he's a board member for the Center for Ethics in Science and Technology.

And he serves as the San Diego representative for the Parkinson's Action Network, which lobbies elected officials on policies regarding Parkinson's research and treatment.

Higgins is a good choice for the stem cell agency's board not only because of his scientific and medical expertise, but also his personal qualities, said Jerry Henberger, executive director of the local Parkinson's association.

"He's patient, thoughtful, extremely intelligent and a great leader," Henberger said. "We're excited about Parkinson's getting a voice. We know he'll do a great job."

Joe Panetta, a member of the Independent Citizens' Oversight Committee, welcomed Higgins to the board. Panetta is president and chief executive of Biocom, the San Diego-based life science trade group.

Tissue development 'roadmap' created to guide stem cell medicine

15 hours ago

In a boon to stem cell research and regenerative medicine, scientists at Boston Children's Hospital, the Wyss Institute for Biologically Inspired Engineering at Harvard University and Boston University have created a computer algorithm called CellNet as a "roadmap" for cell and tissue engineering, to ensure that cells engineered in the lab have the same favorable properties as cells in our own bodies. CellNet and its application to stem cell engineering are described in two back-to-back papers in the August 14 issue of the journal Cell.

Scientists around the world are engaged in culturing pluripotent stem cells (capable of forming all the body's tissues) and transforming them into specialized cell types for use in research and regenerative medicine. Available as an Internet resource for any scientist to use, CellNet provides a much needed "quality assurance" measure for this work.

The two papers also clarify uncertainty around which methods are best for stem cell engineering, and should advance the use of cells derived from patient tissues to model disease, test potential drugs and use as treatments. For example, using CellNet, one of the studies unexpectedly found that skin cells can be converted into intestinal cells that were able to reverse colitis in a mouse model.

"To date, there has been no systematic means of assessing the fidelity of cellular engineeringto determine how closely cells made in a petri dish approximate natural tissues in the body," says George Q. Daley, MD, PhD, Director of the Stem Cell Transplantation Program at Boston Children's and senior investigator on both studies. "CellNet was developed to assess the quality of engineered cells and to identify ways to improve their performance."

Gene Signatures

CellNet applies network biology to discover the complex network of genes that are turned on or off in an engineered cell, known as the cell's Gene Regulatory Network or GRN. It then compares that network to the cell's real-life counterpart in the body, as determined from public genome databases. Through this comparison, researchers can rigorously and reliably assess:

"CellNet will also be a powerful tool to advance synthetic biologyto engineer cells for specific medical applications," says James Collins, PhD, Core Faculty member at the Wyss Institute and the William F. Warren Distinguished Professor at Boston University, co-senior investigator on one of the studies.

Putting CellNet to the Test

The researchersincluding co-first authors Patrick Cahan, PhD and Samantha Morris, PhD, of Boston Children's, and Hu Li, PhD, of the Mayo Clinic, first used CellNet to assess the quality of eight kinds of cells created in 56 published studies.

Trying out a stem cell facial

TO SOME people, the term stem cell may seem kind of taboo. I personally would not want something from animals injected into my system. But Im okay with non-invasive treatments, so I was interested to try out a plant-based stem cell facial.

After cleansing and toning, cotton pads moistened with a clear solution were laid on my eyelids to protect them from a three-minute steaming session. This was followed by a special tool called a scrubber that kind of looks like a computer mouse, but helps to remove dead skin cells and unblock pores without using the rather painful pricking tool.

Next, a rejuvenating gel was applied, followed by the plant-derived stem cell formula. A unique cooling machine was used to massage it into the skin for 10 minutes. Using this machine for cold electrophoresis helps the skin absorb serums and vitamins, without having to use injections. This was great for someone like me, who is wary of invasive treatments. The cooling machine feels like having an ice-cold metal ball massaged on the face; very invigorating, indeed.

Just when I thought my skin already got a lot of pampering, the stem cell was followed by a face mask full of natural vitamins. While it penetrated into my skin, I was given an arm and foot massage, which was nice for further relaxation.

With my combination skin, I looked pretty greasy right afterwards. When I woke up the next day, I didnt see a visible difference in my skin, but it was very smooth and supple to the touch. You may not see instant results with a treatment like this, but its a good treatment to maintain radiance, softness and hydration from beneath the surface of the skin.

This type of facial is not recommended for those with oily or acne-prone skin because the added oiliness may exacerbate problems, but it is ideal for those with dry or mature skin, as it is deeply nourishing and moisturizing. After the first treatment or over time, depending on the condition of your skin, stem cell diminishes fine lines, prevents wrinkles, and promotes cell renewal (a process that slows with age) to give that glowing look that signifies healthy, youthful skin.

I tried out the stem cell facial at Lohas skin and slimming center on Paseo Saturnino, Banilad. Its a more upscale experience here with your own room, as opposed to being in one large room with dividers, in case privacy is an issue for you. All of their machines and products are brought in from Korea and their staff, like my therapist Jennylyn, are highly knowledgeable and know just how much pressure to apply during the treatment. The service, facilities and products used add up to a luxurious treatment session that makes one feel very pampered.

Stem cell discovery: Australian scientists make significant find while studying zebrafish

Australian scientists studying zebrafish have stumbled upon what they say is one of the most significant discoveries in stem cell research.

In research published on Thursday in the journal Nature, the Monash University scientists revealed that they uncovered how one of the most important stem cells in blood and bone marrow, the haematopoietic stem cell (HSC), is formed.

Professor Peter Currie, from Monash University's Australian Regenerative Medicine Institute, said the discovery brought researchers closer to growing HSCs in a lab.

"HSCs are the basis of bone marrow transplantations as a therapy, so when a leukaemia patient receives bone marrow, it's really these HSCs that do the heavy lifting," Professor Currie said.

"So when clinicians do bone marrow transplants, they need to find a matching donor recipients and we know that's a hit or miss procedure.

"So for many years people have been trying to make HSCs in the dish, and they've had very little success in doing this."

Professor Currie, who led the study, said the discovery brought scientists much closer to achieving that aim.

"It's the discovery of a completely new cell type that basically is required to give instructions to the HSC to make it become what it needs to become," he said.

"It means we now understand how HSC form in the body better, we can use that information to try to grow these cells in the dish and we hope that will lead to better treatment for people with leukaemia and blood disorders."

Professor Currie said he specialises in muscle stem cell biology and accidentally came across the discovery while studying muscle stem cells in zebrafish.

Cedars-Sinai Heart Institute Opens First-of-its-Kind Research Stem Cell Clinic for Cardiac Patients

Available for logged-in reporters only

Newswise LOS ANGELES (Aug. 12, 2014) Regenerative medicine experts at the Cedars-Sinai Heart Institute have opened a new clinic to evaluate heart and vascular disease patients for participation in stem cell medical studies.

Led by Eduardo Marbn, MD, PhD, director of the Cedars-Sinai Heart Institute, and Timothy Henry, MD, director of the Heart Institutes Cardiology Division, the doctors and researchers at the Cedars-Sinai Heart Institute Regenerative Medicine Clinic use a scientific approach to assess the possible benefits of stem cells to repair damaged or diseased cardiovascular tissues. The clinic is believed to be the first at a major U.S. academic medical center dedicated to matching patients with appropriate stem cell clinical trials, whether those research interventions are available at the medical center or at other institutions.

The Heart Institute Regenerative Medicine Clinic offers consultative services for patients with heart and vascular disease who may qualify for investigative stem cell therapy. The goal is to provide research options to patients who remain symptomatic on their current management regimen, or for patients with stable heart disease who are concerned about disease progression.

Over the past decade, medical experts have predicted that in the future, stem cell therapies would transform heart disease treatment and save lives, said Shlomo Melmed, MD, dean of the Cedars-Sinai faculty and the Helene A. and Philip E. Hixon Distinguished Chair in Investigative Medicine. At Cedars-Sinai, we have a track record of successfully directing cardiac stem cell studies as well as transferring innovations from the laboratory to the patient bedside.

In 2009, Marbn and his team completed the worlds first procedure in which a patients own heart tissue was used to grow specialized heart stem cells. The specialized cells were then injected back into the patients heart in an effort to repair and re-grow healthy muscle in a heart that had been injured by a heart attack. Results, published in The Lancet in 2012, showed that one year after receiving the stem cell treatment, heart attack patients demonstrated a significant reduction in the size of the scar left on the heart muscle after a heart attack.

Henry has served as principal investigator of multiple large, multicenter trials in acute coronary syndromes, myocardial infarction and angiogenesis, including several ongoing cardiovascular stem cell trials. He also is principal investigator for one of seven NIH Clinical Cardiovascular Stem Cell Centers.

Our goal is to help make stem cells a regular treatment option for heart disease, Henry said. Right now, many patients with advanced heart disease have limited treatment options. Stem cells offer not only hope but a real chance of a game-changing treatment.

As part of each patients assessment in the Heart Regenerative Medicine Clinic, physicians will evaluate patients interested in participating in stem cell clinical trials at Cedars-Sinai and, for patients willing to travel at other medical institutions across the nation. For patients willing to travel to participate in research, Cedars-Sinai physicians will work closely with investigators at other centers to expedite referrals and seamlessly transfer all relevant medical records.

UCSD Looking For Spinal Cord Injury Patients To Test Stem Cell Treatment

The UC San Diego Health System put out a call Monday for eight spinal cord injury patients to take part in a five-year test of the safety of a new treatment involving neural stem cells.

The researchers are looking for people who suffered an injury to the middle or lower levels of the spine's thoracic vertebrae between one and two years ago. According to UCSD, the injury must be between the seventh and 12th thoracic vertebrae.

"The goal of this study is to evaluate the safety of transplanting neural stem cells into the spine for what one day could be a treatment for spinal cord injuries," said Dr. Joseph Ciacci, the study's principal investigator and a neurosurgeon at UC San Diego Health System. "The study's immediate goal, however, is to determine whether injecting these neural stem cells into the spine of patients with spinal cord injury is safe."

The doctors also want to know how long the transplanted stem cells will last, and whether drugs designed to prevent rejection by the immune system are effective, according to UCSD Health.

The researchers will also look for possible changes in motor and sensory function, bowel and bladder function, and pain levels.

The stem cells were tested in laboratory rats by Ciacci and Dr. Martin Marsala, of the UC San Diego School of Medicine. They detected signs of improved motor function with minimal side effects. The cells have also been tested for safety in human patients with amyotrophic lateral sclerosis commonly known as ALS or Lou Gehrig's Disease.

UCSD cautioned prospective test subjects that since human tests are just beginning, unforeseen risks, complications or unpredictable outcomes are possible.

The clinical trial at UC San Diego Health System is funded by Neuralstem Inc. and was launched and supported by the UC San Diego Sanford Stem Cell Clinical Center. The center was recently created to "advance leading-edge stem cell medicine and science, protect and counsel patients, and accelerate innovative stem cell research into patient diagnostics and therapy," according to UCSD.

Available for logged-in reporters only

Newswise Researchers at the University of California, San Diego School of Medicine have launched a clinical trial to investigate the safety of neural stem cell transplantation in patients with chronic spinal cord injuries. This Phase I clinical trial is recruiting eight patients for the 5-year study.

The goal of this study is to evaluate the safety of transplanting neural stem cells into the spine for what one day could be a treatment for spinal cord injuries, said Joseph Ciacci, MD, principal investigator and neurosurgeon at UC San Diego Health System. The studys immediate goal, however, is to determine whether injecting these neural stem cells into the spine of patients with spinal cord injury is safe.

Related goals of the clinical trial include evaluating the stem cell grafts survival and the effectiveness of immunosuppression drugs to prevent rejection. The researchers will also look for possible therapeutic benefits such as changes in motor and sensory function, bowel and bladder function, and pain levels.

Patients who are accepted for the study will have spinal cord injury to the T7-T12 level of the spines vertebrae and will have incurred their injury between one and two years ago.

All participants will receive the stem cell injection. The scientists will use a line of human stem cells approved by the U.S. FDA for human trials in patients with chronic traumatic spinal injuries. These cells were previously tested for safety in patients with amyotrophic lateral sclerosis (ALS).

Since stem cell transplantation for spinal cord injury is just beginning clinical tests, unforeseen risks, complications or unpredictable outcomes are possible. Careful clinical testing is essential to ensure that this type of therapy is developed responsibly with appropriate management of the risks that all medical therapies may present.

Pre-clinical studies of these cells by Ciacci and Martin Marsala, MD, at the UC San Diego School of Medicine, showed that these grafted neural stem cells improved motor function in spinal cord injured rats with minimal side effects indicating that human clinical trials are now warranted.

This clinical trial at UC San Diego Health System is funded by Neuralstem, Inc. and was launched and supported by the UC San Diego Sanford Stem Cell Clinical Center. The Center was recently created to advance leading-edge stem cell medicine and science, protect and counsel patients, and accelerate innovative stem cell research into patient diagnostics and therapy.

A stem cell study shows promising results for severe stroke patients

An injection of stem cells into the brains of recent stroke victims might help their long-term recovery, according to a promising but preliminary study out of the United Kingdoms Imperial College London.

A strokes occurs when there is an interruption or reduction of blood flow to the brain. The particular stem cells used in this treatment could, in theory, encourage the growth of new blood vessels in the brain, as the BBC explained. Blood vessel growth could help patients suffering from a severe stroke regain the ability to walk, talk and take care of themselves to a greater degree, and with greater speed, than previously possible during recovery. But again, this is just a preliminary study a guide for researchers to a potential new path for stem-cell based stroke treatments.

Working on the hypothesis that this approach mighthave an effect on more recent stroke cases, researcherstreatedpatients within a week of their strokes. The stroke patients in the pilot study demonstrated signs of recovery over a six-month period after treatment. But the small study of just five patients did not demonstrate whether that improvement came from the therapy or from the hospital care the stroke patients also received during the six-month time frame.

However, the sample demonstrated a somewhat remarkable survival and tentative recovery rate, no matter the cause.Four patients of the five were recovering from the most severe form of stroke, which overall has an extremely low rate of patients who survive and can eventually live independently. At the end of the study, all four of those patients were alive. Three were able to live independently.

The next step, the ICLs consultant neurologist Paul Bentley told the Guardian, would be a larger, controlled and randomized study with 50 patients. That study, for which the group is currently seeking funding, would look to discernwhether the pilot studys promising results really had anything to do with the treatment.
