Research Abstract
Trained at UCLA's Brain Research Institute, Dr. Schwartz is a full-time stem cell biologist and holds the Senior Scientist position at the Children’s Hospital of Orange County (CHOC) Research Institute. Dr. Schwartz is the Director and Founder of the National Human Neural Stem Cell Resource, and an Associate Research Biologist at the University of California, Irvine.

Dr. Schwartz' early work included studies of several models of energy failure-induced brain damage as well as preclinical and clinical studies of pharmacologic agents aimed at maintaining cerebral perfusion and/or neuroprotection. This work involved translational research aimed toward improving the treatment of neonatal and pediatric intensive care unit patients with brain injury and disease. For the last fourteen years, he has been involved in the harvest of neural stem cells in human brains from patients that have died with neurogenetic disease and the research in his laboratory is directed towards understanding the factors influencing the behavior of neural stem cells in the normal and neurogenetically diseased brain. This work now includes the use of neural stem cells derived from induced pluripotent stem cells. Much of this work has been directed towards evaluating the efficacy of neural stem cell transplantation in animal models of degenerative eye diseases and of neurogenetic disease. This latter work has direct application to the clinical use of stem cells for the treatment of children with neurodevelopmental disorders, the major clinical focus of Dr. Schwartz and his clinical colleagues at CHOC. More recent work is focused on using neural stem cells derived from patients with autism in an effort to define new therapeutic and diagnostic targets for this most prevalent neurodevelopmental disorder.

Dr. Schwartz’ laboratory currently consists of a PhD Scientist and three Research Associates/Laboratory Technicians. Dr. Schwartz regularly participates in special study sections on stem cells at the NIH and reviews grant applications and manuscripts for a large number of other granting agencies and journals. He has recently been a Member of the Distinguished Editors Panel for NIH Challenge Grant applications that proposed to use human pluripotent (embryonic) stem cells. Dr. Schwartz also regularly disseminates stem cell research information to the lay public by way of lectures and the print, television, and radio media.
