Summary:
Scientists have determined that bone marrow stromal stem cells may aid in stroke recovery. The study examining the effects of a systematic administration of either rat (allogenic) or human (xenogenic) bone marrow stem cells (MSC) administered to laboratory rats one day after their simulated strokes found "significant recovery" of motor behavior on the first day.

A research study from the Farber Institute for Neurosciences and the Department of Neuroscience at Thomas Jefferson University determines bone marrow stromal stem cells may aid in stroke recovery. The results can be found in Cell Transplantation -- The Regenerative Medicine Journal.

The study examining the effects of a systematic administration of either rat (allogenic) or human (xenogenic) bone marrow stem cells (MSC) administered to laboratory rats one day after their simulated strokes found "significant recovery" of motor behavior on the first day. Early administration was found to be more effective than administration seven days after the simulated strokes.

"The timing of stem cell treatment was critical to the magnitude of the positive effects," said the study's lead author, Lorraine Iacovitti, Ph.D., professor, Department of Neuroscience at Jefferson Medical College of Thomas Jefferson University. "In the host animals we found profound changes and preserved brain structure along with long-lasting motor function improvement."

According to Dr. Iacovitti, there has been little research into just how stem cell transplantation modifies inflammatory and immune effects as well as promotes regenerative effects, such as blood vessel growth. They observed increased activation of microglia as well as modification of the circulating levels of cytokines and growth factors, including elevated VEGF and new blood vessel formation (angiogenesis) following transplantation.

"The mechanism through which MSCs achieve these remarkable effects remains elusive," said Dr. Iacovitti. "It is possible that activated glia cells (nonneuronal cells that perform a number of tasks in the brain) may play some role in the response, perhaps by partitioning off the infarcted region and limiting the spread of ischemic brain damage without inducing scar formation."

The research team concluded that there was "little doubt" that the administration of stem cells can modify the cellular and molecular landscape of the brain and blood, limiting damage and protecting the stroke-injured brain.

Other Jefferson researchers participating in this study included Robert Rosenwasser, M.D. (Neurological Surgery) and Ming Yang, M.D., Ph.D. (Neuroscience).

Gilead's $1000-a-Pill Drug Could Cure Hep C in HIV-Positive People

TheStreet (July 21, 2014) New research shows Gilead Science's drug Sovaldi helps in curing hepatitis C in those who suffer from HIV. In a medical study, the combination of Gilead's Hep C drug with anti-viral drug Ribavirin cured 76% of HIV-positive patients suffering from the most common hepatitis C strain. Hepatitis C and related complications have been a top cause of death in HIV-positive patients. Typical medication used to treat the disease, including interferon proteins, tended to react badly with HIV drugs. However, Sovaldi's %1,000-a-pill price tag could limit the number of patients able to access the treatment. TheStreet's Keris Lahiff reports from New York. Video provided by TheStreet
