Embargo Policy: Articles for STEM CELLS and STEM CELLS Translational Medicine are embargoed for release until 9 a.m. Eastern U.S. time on the day the article is posted online. This policy applies to members of the media, authors, institutions' public information officers, and the public. Authors may not discuss their work with the media until 1 week before the mailing date or 1 week before online posting of the article, whichever is earlier, and must ensure that the media representatives agree to abide by the embargo policy. STEM CELLS Translational Medicine may refuse to publish a manuscript, despite acceptance for publication, if it has been prematurely released to the press.

In an article featured in the latest issue of STEM CELLS, a research group from Stanford University describes a novel regimen for quashing this immunologic barrier — a short-course treatment with two costimlation-adhesion blockade agents, allowing engraftment of transplanted differentiated stem cells and their prolonged survival in tissue.

However, a new study released today in STEM CELLS Translational Medicine indicates that endothelial precursor cells, which are found in the bone marrow, umbilical cord blood, and as very rare cells in peripheral blood, could make a significant difference for these patients’ recovery — even in the later stages of stroke. In animal studies, the treatment minimized the initial brain injury and helped repair the stroke damage.

“In this work, we describe a highly innovative gene therapy approach, which is being developed along with the NIH and the FDA. Specifically, our group has developed an allogeneic neural stem cell line that is a carrier for a virus that can selectively infect and break down cancer cells,” explained Dr. Lesniak, the University of Chicago’s director of neurosurgical oncology and neuro-oncology research at the Brain Tumor Center.

The stem cell line, called HB1.F3 NSC, was recently approved by the FDA for use in a phase I human clinical trial.

As such, it could lead to a purer, safer therapeutic grade of stem cells for use in regenerative medicine.

The discovery of iPSCs holds great promise for regenerative medicine since it is possible to produce patient-specific iPSCs from the individual for potential autologous treatment — that is, treatment using the patient’s own cells. This avoids the possibility of rejection and numerous other harmful side effects.

In addition, the research demonstrates that the transplanted organ retained its immunologically privileged state during a subsequent transplantation into another naïve recipient.

“Dental cavities and inflammation of the surrounding pulp is a challenging public health issue, as tooth decay not only can cause a patient great pain but it also can lead to other serious health issues including heart disease,” explained Misako Nakashima, DDS, Ph.D., of the National Center for Geriatrics and Gerontology in Obu, Japan. “Generally we treat deep cavities by capping the tooth and removing any inflamed pulp surrounding it. But this has limited success and the problem frequently progresses until the tooth must be removed.”

But now a research team reports that it has developed a way to speed up the process. Their work, which involves the creation of a highly stable and sensitive liver stem cell model, is reported in the latest issue of STEM CELLS Translational Medicine.

“Liver toxicity is the second most common cause of human drug failure,” explained David Hay, Ph.D., of the University of Edinburgh’s MRC Centre for Regenerative Medicine, who led the team made up of university colleagues and scientists from Bristol-Myers Squibb, Princeton, N.J. “But one major bottleneck in safety testing new drugs has been finding a routine supply of good quality primary human hepatocytes from the desired genetic background.”

Researchers at the Leiden University Medical Center’s Department of Immunohematology and Blood Transfusion in Leiden, The Netherlands, led by Helene Roelofs, Ph.D., conducted the study. They were seeking an alternative to bone marrow for stem cell therapies because of the low number of stem cells available in marrow and also because harvesting them involves an invasive procedure.

“Adipose tissue is an interesting alternative since it contains approximately a 500-fold higher frequency of stem cells and tissue collection is simple,” Dr. Roelofs said.

Many medical experts have long believed that neural stem cells (NSCs) have great potential for treating neurological diseases. However, the problem is that just a small number of NSCs can be transplanted into the brain, yielding relatively low levels of new cell growth and, thus, a limited effect. “We wanted to investigate whether using a specific population of neural cells would help increase the number of mature brain cells that the stem cell graft yields,” Dr. Wolfe explained.

“Cell transplantation strategies therefore typically introduce a stress challenge at the time of transplantation as the cells are switched from 20 percent to 3 percent oxygen, which is the average in adult organs,” she added.
