In an article appearing online today in the journal Science, a group of researchers, including University of Rochester neurologist Steve Goldman, M.D., Ph.D., review the potential and challenges facing the scientific community as therapies involving stem cells move closer to reality.
The review article focuses on pluripotent stem cells (PSCs), which are stem cells that can give rise to all cell types. These include both embryonic stem cells, and those derived from mature cells that have been
induced- a process typically involving a patient's own skin cells – so that they possess the characteristics of stem cells found at the earliest stage of development. These cells can then be differentiated, through careful manipulation of chemical and genetic signaling, to become virtually any cell type found in the body.
The article addresses the current state of efforts to apply PSCs to treat a number of diseases, including diabetes, liver disease, and heart disease. Goldman, a distinguished professor and co-director of the University of Rochester School of Medicine and Dentistry Center for Translational Neuromedicine, reviewed the current state of therapies for neurological diseases.
