Newswise ROCHESTER, Minn. -- Mayo Clinic researchers have found a way to detect and eliminate potentially troublemaking stem cells to make stem cell therapy safer. Induced Pluripotent Stem cells, also known as iPS cells, are bioengineered from adult tissues to have properties of embryonic stem cells, which have the unlimited capacity to differentiate and grow into any desired types of cells, such as skin, brain, lung and heart cells. However, during the differentiation process, some residual pluripotent or embryonic-like cells may remain and cause them to grow into tumors.

Pluripotent stem cells show great promise in the field of regenerative medicine; however, the risk of uncontrolled cell growth will continue to prevent their use as a therapeutic treatment, says Timothy Nelson, Ph.D., M.D., lead author on the study, which appears in the October issue of STEM CELLS Translational Medicine.

Using mouse models, Mayo scientists overcame this drawback by pretreated stem cells with a chemotherapeutic agent that selectively damages the DNA of the stem cells, efficiently killing the tumor-forming cells. The contaminated cells died off, and the chemotherapy didnt affect the healthy cells, Dr. Nelson says.

The goal of creating new therapies is twofold: to improve disease outcome with stem cell-based regenerative medicine while also ensuring safety. This research outlines a strategy to make stem cell therapies safer for our patients while preserving their therapeutic efficacy, thereby removing a barrier to translation of these treatments to the clinic, says co-author Alyson Smith, Ph.D.

Stem cell therapies continue to be refined and improved. Researchers are finding that stem cells may be more versatile than originally thought, which means they may be able to treat a wider variety of diseases, injuries and congenital anomalies. Stem cell therapy is an emerging regenerative strategy being studied at Mayo Clinic.

By harnessing the potential of regenerative medicine, well be able to provide more definitive solutions to patients, says Andre Terzic, M.D., Ph.D., co-author and director of Mayo Clinics Center for Regenerative Medicine.

Other members of the Mayo research team included Clifford Folmes, Ph.D., Katherine Hartjes, Natalie Nelson and Saji Oommen, Ph.D. The research was supported by the Todd and Karen Wanek Family Program for Hypoplastic Left Heart Syndrome, National Institutes of Health New Innovator Award OD007015-01, and a Mayo Clinic Center for Regenerative Medicine accelerated research grant.

Mayo Clinic Finds Way to Weed Out Problem Stem Cells, Making Therapy Safer

(WGBA/NBC) - It is a story that gives hope to pet owners all over the country stem cell therapy for animals suffering from problems like arthritis or hip displaysia.

Stem cells are taken out of the dog's fatty tissue are harvested then injected into problem areas leaving the dogs completely healed.

"We couldn't take him on walks, he just laid around a lot," said Keith Nosowiak, Deniro's owner.

"We'd hear whimpering overnight, she'd take a few steps and she would sit down," said Luther Kortbein, Shadow's owner.

Until two months ago, Deniro suffered from severe arthritis, Shadow from hip displaysia.

Deniro's owner thought he may even have to put his German shepherd down.

"We felt we had a decision to make with his quality of life and being in pain we didn't want him to be in pain," Noskowiak said.

Shadow's owner was willing to try anything to cure her.

"Whatever the cost needed to get this done we were willing to do," Kortbein said.

Then Packerland Veterinary Center offered them stem cell therapy by using the dogs own stem cells and then injecting them back into the bloodstream joints.

Probe sought into status of stem cell therapy in the Philippines

The California stem cell agency faces
no easy task in trying to translate basic research findings into
something that can be used to treat patients and be sold commercially.

“One goal of scientific publication
is to share results in enough detail to allow other research teams to
reproduce them and build on them. However, many recent reports have
raised the alarm that a shocking amount of the published literature
in fields ranging from cancer biology to psychology is not
reproducible.”

“First, I think it is important to
accept that there is a crisis affecting preclinical research. Recent
studies estimate that 70% of preclinical research cannot be
reproduced. This is the research that should form the foundation upon
which new discoveries can be made to enhance health, lengthen life,
and reduce the burdens of illness and disability. The
irreproducibility of preclinical research is a significant impediment
to the achievement of these goals. To solve this problem requires
immediate and concrete action. It is not enough to make
recommendations and issue guidelines to researchers. Funders must act
to ensure they fund researchers to produce high quality reproducible
research. One such way to do so, is to reward, or require,
independent validation of results. The reproducibility initiative
provides a mechanism for independent validation, allowing the
identification of high quality reproducible research. It is vital
that funders act now to address this problem, to prevent the wasted
time and money that is currently spent funding non-reproducible
research and to prevent the erosion of public trust and support for
research.”
