Caruth, Jr. Scholar in Biomedical Research.
A stem cell therapy did not improve walking ability in people with peripheral artery disease, although exercise did lead to significant improvements, according to a new study. This is the largest trial of this type of therapy in people with blockages in leg arteries. Scientists were disappointed that stem cell therapy didn’t improve walking, because earlier research suggested it could be beneficial.
In a study published in Stem Cell Reports, Rui Zhao and colleagues have partly solved a long-unanswered basic question about stem cells — why are pluripotent stem cells that have mutations to block the production of microRNAs unable to differentiate?

Nathan Bryan, PH.D., one of the nation’s leading experts on critically important role of nitric oxide in health and disease prevention, told attendees of the Pacific Regenerative Medicine 2017 Conference this morning that, “Stem cells are the future of medicine and are required for our body to heal itself; however, their success depends on the body producing enough nitric oxide to support their healing properties. Simply, put, without the right amount of NO in the body, our own stem cells fail to function and furthermore, those receiving stem cell therapy may have limited success without proper NO production.”

Study in journal Nature Medicine demonstrates, for the first time, that glioblastoma (GBM) is driven by two distinct subsets of cancer stem cells. Moreover, each subtype of glioma stem cells is driven by distinct transcriptional programs for growth and treatment resistance, and these different cell populations correspond to well-known morphological differences within the GBM itself. More importantly, the researchers found that while chemotherapeutic agents targeting each subtype achieve modest efficacy alone, they are synergistic when combined as demonstrated in a mouse model.

The technique makes it possible to study motor neurons of the human central nervous system in the lab. Unlike commonly studied mouse motor neurons, human motor neurons growing in the lab would be a new tool since researchers can’t take samples of these neurons from living people but can easily take skin samples.
Researchers from the Perelman School of Medicine at the University of Pennsylvania have made a discovery about muscular dystrophy disorders that suggest new possibilities for treatment. In a study published today online in Stem Cell Reports, researchers found that stem cells in the muscles of muscular dystrophy patients may, at an early age, lose their ability to regenerate new muscle, due to shortened telomeres
Researchers in Germany have demonstrated that hematopoietic stem cell (HSC) transplants can be improved by treatments that temporarily prevent the stem cells from dying. The approach, which is described in a paper to be published September 7 in The Journal of Experimental Medicine, could allow those in need of such transplants, including leukemia and lymphoma patients, to be treated with fewer donor stem cells while limiting potential adverse side effects.
