(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.

Newswise MADISON, Wis. 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 what's 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 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.

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.

Cipla bets big on cell therapy

By Stem Cell Treatment

In India, stem cell biz may touch $8 b by 2015

Mumbai, March 21:

Stem cells are set to be a major branch of medical treatment, says Cipla Chairman YK Hamied. Regenerative medicine, or cell therapy, is a rapidly emerging area of biomedical research and would be an ideal supplement for existing medical treatments, he added.

Cell therapy refers to treatments that are founded on the concept of producing new cells to replace malfunctioning or damaged cells as a vehicle to treat disease and injury.

We have a research unit in Malaysia that is conducting research on stem cells, Hamied said while speaking about Stempeutics Research with which it has an alliance. The Manipal Group-promoted Stempeutics is developing stem cell-based medicinal products with facilities in Kuala Lumpur (Malaysia) and Bangalore.

We are partners in the Bangalore company, he said. The enormous potential of stem cells in the treatment of chronic and several incurable diseases is boosting the overall stem cells therapy market, he added.

Poised to reach an estimated $88.3 billion by 2015, the global stem cells market has been growing at a compounded annual growth rate of 14.8 per cent, driven by the increasing demand of stem cell therapy.

In India, the stem cell business is expected to touch $8 billion (48,880 crore today) by 2015. With three phase II clinical trials in progress in India for critical limb Ischemia (meaning restriction in blood supply to tissues), osteoarthritis and liver cirrhosis Stempeutics aims to bring the first product into the Indian and Malaysian markets by 2015.

Under the alliance, Cipla has invested over 50 crore in Stempeutics, with a focus on research of stem cell-based products, and has done something similar in China, where it has streamlined its investments towards its core business. The drug-maker recently exited a significant part of its investment in its Chinese partner Desano Holdings.

Despite the lack of legislation and awareness, besides quality and ethical issues that have deterred growth of the stem cell therapy business in India, the country remains the top priority for the Mumbai-based drug-maker, the Cipla Chairman told Business Line.

Stem cell study finds source of earliest blood cells during development

PUBLIC RELEASE DATE:

20-Mar-2014

Contact: Matthew Inlay minlay@uci.edu 949-824-8226 University of California - Irvine

Irvine, Calif., March 20, 2014 Hematopoietic stem cells are now routinely used to treat patients with cancers and other disorders of the blood and immune systems, but researchers knew little about the progenitor cells that give rise to them during embryonic development.

In a study published April 8 in Stem Cell Reports, Matthew Inlay of the Sue & Bill Gross Stem Cell Research Center and Stanford University colleagues created novel cell assays that identified the earliest arising HSC precursors based on their ability to generate all major blood cell types (red blood cells, platelets and immune cells).

This discovery of very early differentiating blood cells, Inlay said, may be very beneficial for the creation of HSC lines for clinical treatments.

"The hope is that by defining a set of markers that will allow us to make purer, cleaner populations of these precursor cells, we'll be able to reveal the key molecular events that lead to the emergence of the first HSCs in development. This could give us a step-by-step guide for creating these cells in a dish from pluripotent stem cell lines" added Inlay, who is an assistant professor of molecular biology & biochemistry at UC Irvine and conducted the study while a postdoctoral researcher in the Irving Weissman lab in the Institute for Stem Cell Biology and Regenerative Medicine at Stanford University.

###

The work was performed in collaboration with Thomas Serwold, now an assistant professor in the Joslin Diabetes Center at Harvard Medical School.

The research reported in this article was supported by the National Institutes of Health (grants 5 T32 AI07290, R01HL058770, R01CA86085 and U01HL09999), the California Institute for Stem Cell Research (grants T1-00001, RT2-02060 to I.L.W.), the Harvard Stem Cell Institute, the Siebel Stem Cell Institute, the Thomas and Stacey Siebel Foundation, and the Virginia and D.K.

Irvine Stem Cell Treatment Center: Public Seminar

By Stem Cell Treatment

Irvine, CA (PRWEB) March 21, 2014

The Irvine Stem Cell Treatment Center, PC, located in Irvine, CA, announces a free public seminar on the use of stem cells for various degenerative and inflammatory conditions. They will be provided by Dr. Thomas A. Gionis, Surgeon-in-Chief.

The seminar will be held on March 23, 2014 at 2:00pm PSTat 3500 Barranca Parkway, Suite 315, Irvine, CA 92606.

At the Irvine Stem Cell Treatment Center, utilizing investigational protocols, adult adipose derived stem cells (ADSCs) can be deployed to improve patients quality of life with a number of degenerative conditions and diseases. ADSCs are taken from the patients own adipose (fat) tissue (also called stromal vascular fraction (SVF)). Adipose tissue is exceptionally abundant in ADSCs. 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 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 damaged cells. The Irvine Stem Cell Treatment Center only uses autologous stem cells from a person's own fat no embryonic stem cells are used. Our current areas of study include: Heart Failure, Emphysema, COPD, Asthma, Parkinsons Disease, Stroke, Multiple Sclerosis, and orthopedic joint injections. For more information, or if someone thinks they may be a candidate for one of the stem cell protocols offered by 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.StemCellsUSA.net.

About Irvine Stem Cell Treatment Center: The Irvine Stem Cell Treatment Center is an affiliate of the Cell Surgical Network (CSN). 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 Research Protections; and the study is registered with Clinicaltrials.gov, a service of the U.S. National Institutes of Health (NIH).
