As stem cells continue their gradual transition from the lab to the clinic, a research group at the University of Wisconsin-Madison has discovered a new way to make large concentrations of skeletal muscle cells and muscle progenitors from human stem cells.

The new method, described in the journal Stem Cells Translational Medicine, could be used to generate large numbers of muscle cells and muscle progenitors directly from human pluripotent stem cells. These stem cells, such as embryonic (ES) or induced pluripotent stem (iPS) cells, can be made into virtually any adult cell in the body.

Adapting a method previously used to make brain cells, Masatoshi Suzuki, an assistant professor of comparative biosciences in the School of Veterinary Medicine, has directed those universal stem cells to become both adult muscle cells and muscle progenitors.

Importantly, the new technique grows the pluripotent stem cells as floating spheres in high concentrations of two growth factors, fibroblast growth factor-2 and epidermal growth factor. These growth factors urge the stem cells to become muscle cells.

Researchers have been looking for an easy way to efficiently differentiate stem cells into muscle cells that would be allowable in the clinic, says Suzuki. The novelty of this technique is that it generates a larger number of muscle stem cells without using genetic modification, which is required by existing methods for making muscle cells.

Many other protocols have been used to enhance the number of cells that go to a muscle fate, says co-author Jonathan Van Dyke, a post-doctoral fellow in Suzukis laboratory. But whats exciting about the new protocol is that we avoid some techniques that would prohibit clinical applications. We think this new method has great promise for alleviating human suffering.

Last year, Suzuki demonstrated that transplants of another type of human stem cells somewhat improved survival and muscle function in rats that model amyotrophic lateral sclerosis (ALS). Also known as Lou Gehrigs disease, ALS destroys nerves and causes a loss of muscle control. The muscle progenitors generated with Suzukis new method could potentially play a similar role but with enhanced effect.

Importantly, the new technique grows the pluripotent stem cells as floating spheres in high concentrations of two growth factors, fibroblast growth factor-2 and epidermal growth factor. These growth factors "urge" the stem cells to become muscle cells.

"Researchers have been looking for an easy way to efficiently differentiate stem cells into muscle cells that would be allowable in the clinic," says Suzuki. The novelty of this technique is that it generates a larger number of muscle stem cells without using genetic modification, which is required by existing methods for making muscle cells.

Also known as Lou Gehrig's disease, ALS destroys nerves and causes a loss of muscle control. The muscle progenitors generated with Suzukis new method could potentially play a similar role but with enhanced effect.

The new technique can also be used to grow muscle cells from iPS cells from patients with neuromuscular diseases like ALS, spinal muscular atrophy and muscular dystrophy. Thus, the technique could produce adult muscle cells in a dish that carry genetic diseases. These cells could then be used as a tool for studying these diseases and screening potential drug compounds, says Suzuki. "Our protocol can work in multiple ways and so we hope to provide a resource for people who are exploring specific neuromuscular diseases in the laboratory."

The new protocol incorporates a number of advantages. First, the cells are grown in defined supplements without animal products such as bovine serum, enhancing the clinical safety for the muscle stem cells. Second, when grown as spheres, the cells grow faster than with previous techniques. Third, 40 to 60 percent of the cells grown using the process are either muscle cells or muscle progenitors, a high proportion compared to traditional non-genetic techniques of generating muscle cells from human ES and iPS cells.

Suzuki and his group hope that by further manipulating the chemical environment of the spheres of stem cells, they may increase that number, further easing the path toward human treatment.

Wounded Pa. soldier seeks Chinese stem cell cure

By Stem Cell Treatment

YORK, Pa. (AP) - A York County soldier left partially paralyzed when he was shot in Afghanistan nearly two years ago is banking on stem cells to help him regain movement.

Matthew Hanes, 22, of Manchester Township will head to China in April to undergo surgery to repair part of his damaged spinal cord.

Doctors essentially will use minor surgery and stem cell therapy to build a bridge over two vertebrae that were shattered when Hanes was shot.

At the minimum Ill get at least some feeling back where I dont have it in certain places, but I could get everything back if it goes well, Hanes said.

U.S. Army Cpl. Hanes was shot while on patrol in Afghanistan in June 2012. He was left with limited use of his upper body and no use of his lower extremities.

RESEARCH: Soon after he returned to the U.S., Hanes began researching stem cell therapy as possible treatment.

Thats how he found Puhua International Hospital in Beijing, where he will fly on April 1 for the treatment. Hes slated to return stateside later that month.

Its coming up slowly now that I know its on, Hanes said.

During his research, Hanes said he found the U.S. is so far behind on stem cell research compared to some countries in Asia, such as China, and Europe.

For years, the federal government imposed tight restrictions on stem cell research until it was loosened in 2009 by President Barrack Obama.

The furor over fresh-cell therapy (which is NOT stem cell therapy)

By Uncategorized

The Philippines is the biggest market for the popular, if highly controversial, alternative treatment in Germany called fresh-cell therapy (FCT). Fresh cells derived from the fetus of an unborn lamb are injected into patients, and are said to cure a large number of illnesses.

Despite the high cost of the treatment, wealthy Filipinos are undeterred, and typically arrive in droves in a sleepy town outside Frankfurt, their hopes of being cured or rejuvenated pinned on the life of every donor sheep.

Given its renown, its no surprise that questions about the efficacy and safety of FCT has been the subject of discussions among health professionals. There have also been rumors of deaths after FCT.

The proponents of FCT in Germany, however, claim that all talk about patient deaths and questionable safety standards are unfounded, and an uncouth effort to discredit FCT so that the same medical professionals here could promote stem-cell therapy, which is allowed in the country. They deny the rumors of deaths and challenge their accusers to show proof. They also maintain that FCT is a decades-old, legitimate and safe naturopathic treatment.

Theres also a rivalry in Edenkoben between the famous clinic Villa Medica and the breakaway practice of Dr. Robert Janson-Mller, who used to work at the same clinic.

Dr. Mller now administers FCT in a hotel, which doubles as his clinic. This gave rise to talks questioning the standards of a practice that is done in a hotel, not a hospital. Some accounts also say that there have been Filipino patients fooled into believing they were bound for Villa Medica, only to find themselves in Dr. Mullers hotel.

Inquirer Lifestyle visits the two rival clinics in Germany, and we experience firsthand what FCT is all about.

Stem cell findings may offer answers for some bladder defects and disease

By Stem Cell Medicine

PUBLIC RELEASE DATE:

(SACRAMENTO, Calif.) For the first time, scientists have succeeded in coaxing laboratory cultures of human stem cells to develop into the specialized, unique cells needed to repair a patient's defective or diseased bladder.

The breakthrough, developed at the UC Davis Institute for Regenerative Cures and published today in the scientific journal Stem Cells Translational Medicine, is significant because it provides a pathway to regenerate replacement bladder tissue for patients whose bladders are too small or do not function properly, such as children with spina bifida and adults with spinal cord injuries or bladder cancer.

"Our goal is to use human stem cells to regenerate tissue in the lab that can be transplanted into patients to augment or replace their malfunctioning bladders," said Eric Kurzrock, professor and chief of the division of pediatric urologic surgery at UC Davis Children's Hospital and lead scientist of the study, which is titled "Induction of Human Embryonic and Induced Pluripotent Stem Cells into Urothelium."

To develop the bladder cells, Kurzrock and his UC Davis colleagues investigated two categories of human stem cells. In their key experiments, they used induced pluripotent stem cells (iPS cells), which were derived from lab cultures of human skin cells and umbilical blood cells that had been genetically reprogrammed to convert to an embryonic stem cell-like state.

If additional research demonstrates that grafts of bladder tissue grown from human stem cells will be safe and effective for patient care, Kurzrock said that the source of the grafts would be iPS cells derived from a patient's own skin or umbilical cord blood cells. This type of tissue would be optimal, he said, because it lowers the risk of immunological rejection that typifies most transplants.

In their investigation, Kurzrock and his colleagues developed a protocol to prod the pluripotent cells into becoming bladder cells. Their procedure was efficient and, most importantly, the cells proliferated over a long period of time a critical element in any tissue engineering application.

"What's exciting about this discovery is that it also opens up an array of opportunities using pluripotent cells," said Jan Nolta, professor and director of the UC Davis Stem Cell program and a co-author on the new study. "When we can reliably direct and differentiate pluripotent stem cells, we have more options to develop new and effective regenerative medicine therapies. The protocols we used to create bladder tissue also provide insight into other types of tissue regeneration."

"When we can reliably direct and differentiate pluripotent stem cells, we have more options to develop new and effective regenerative medicine therapies. The protocols we used to create bladder tissue also provide insight into other types of tissue regeneration."

UC Davis researchers first used human embryonic stem cells obtained from the National Institutes of Health's repository of human stem cells. Embryonic stem cells can become any cell type in the body (i.e., they are pluripotent), and the team successfully coaxed these embryonic stem cells into bladder cells. They then used the same protocol to coax iPS cells made from skin and umbilical cord blood into bladder cells, called urothelium, that line the inside of the bladder. The cells expressed a very unique protein and marker of bladder cells called uroplakin, which makes the bladder impermeable to toxins in the urine.

The UC Davis researchers adjusted the culture system in which the stem cells were developing to encourage the cells to proliferate, differentiate and express the bladder protein without depending upon signals from other human cells, said Kurzrock. In future research, Kurzrock and his colleagues plan to modify the laboratory cultures so that they will not need animal and human products, which will allow use of the cells in patients.

Kurzrock's primary focus as a physician is with children suffering from spina bifida and other pediatric congenital disorders. Currently, when he surgically reconstructs a child's defective bladder, he must use a segment of their own intestine. Because the function of intestine, which absorbs food, is almost the opposite of bladder, bladder reconstruction with intestinal tissue may lead to serious complications, including urinary stone formation, electrolyte abnormalities and cancer. Developing a stem cell alternative not only will be less invasive, but should prove to be more effective, too, he said.

Stem Cell Therapy for Pets in Summit County Colorado Proves to Be a Success for Local Dog Suffering from Pain

By Uncategorized

Poway, California (PRWEB) March 21, 2014

Ruby, a 10 year old Border Collie mix from Breckenridge, Colorado, has found relief from the pain of arthritis with stem cell therapy by Vet-Stem, Inc. Rubys owners came to Jamie Gaynor, DVM at Frisco Animal Hospital for a second opinion after being told Ruby would need a total hip replacement to relieve her constant pain and discomfort. Her quality of life had diminished so rapidly they feared losing her.

Dr. Gaynor began performing stem cell therapy by Vet-Stem for pets in 2006, in Colorado Springs. Paralleling his specialties in pain management, he has now helped well over one hundred pets in the state of Colorado, and ones that traveled just to have his expertise. His credentials and experience made Dr. Gaynor the perfect fit for helping Rubys worsening bilateral hip arthritis despite aggressive drug therapy. Ruby would become Dr. Gaynors first stem cell therapy case at Frisco Animal Hospital; Summit Countys first and oldest animal hospital.

Ruby was in constant pain and discomfort. She had to be carried up stairs and could not go on car rides; her second favorite thing to do. Her quality of life was diminishing rapidly, and we thought we were losing her, explained Rubys owners.

Rubys stem cell procedure consisted of a small fatty tissue collection, which was sent overnight to Vet-Stems lab in California for processing. Once Rubys fat was processed, and stem cells were extracted, fresh doses of her stem cells were sent overnight back to Dr. Gaynor in injectable doses. Within 48hrs of collecting a fat sample from Ruby, Dr. Gaynor was able to inject stem cells into each of her arthritic, painful hips, making Ruby his first stem cell therapy case in Summit County.

Dr. Gaynor and Rubys owners were both pleased with the successful outcome of the procedure, and had the opportunity to share during her 30 day recheck. Ruby is back! She has regained her playfulness, sassy, bossy, collie attitude. She has resumed going for car rides and can stand up and stabilize herself. She jumps out of the car without hesitation. She ascends and descends the stairs like she used to, her owners remarked about Rubys physical performance.

Her entire disposition and expressions are so animated and relaxed. I forgot how she used to smile, hold her ears up, and have endless energy. She is definitely out of pain, and her mobility is at 80%! The best part is, that she continues to heal and get stronger each week. This procedure is hands down the most effective, least traumatic therapy available, especially for the older dog, Rubys owners expressed.

About Vet-Stem, Inc. Vet-Stem, Inc. was formed in 2002 to bring regenerative medicine to the veterinary profession. The privately held company is working to develop therapies in veterinary medicine that apply regenerative technologies while utilizing the natural healing properties inherent in all animals. As the first company in the United States to provide an adipose-derived stem cell service to veterinarians for their patients, Vet-Stem, Inc. pioneered the use of regenerative stem cells in veterinary medicine. The company holds exclusive licenses to over 50 patents including world-wide veterinary rights for use of adipose derived stem cells. In the last decade over 10,000 animals have been treated using Vet-Stem, Inc.s services, and Vet-Stem is actively investigating stem cell therapy for immune-mediated and inflammatory disease, as well as organ disease and failure.
