Guest:

Dr. Pamela Robey is a senior investigator at the National Institute of Dental and Craniofacial Research at the NIH. Dr. Robey’s work focuses on skeletal biology, and the characteristics and biological properties of bone marrow stromal cells, a subset of which are multipotent skeletal stem cells.  In late September, Dr. Robey co-authored a commentary article in Nature discussing the ever famous, but dubious, mesenchymal stem cell. She comes on the show to talk about this and more.
