c outcomes. Their research is aimed at discovering a potential mechanism underlying the BBB repair produced by stem cell transplantation.

"We believe that a regenerative mechanism involving the repair of the damaged BBB by endothelial progenitor cells (EPCs) derived from bone marrow is critical to the successful outcome of cell therapy in stroke," explained Dr. Garbuzova-Davis. "Whereas other cell-based technologies are largely designed to circumvent the BBB for delivery of cells or drugs from the periphery into the brain, we are taking a novel approach of repairing the BBB damage to lead to a therapeutic outcome for stroke victims."

According to the investigators, the site-specific EPC recruitment, followed by blood vessel repair processes, is important to exploiting BBB repair, a neglected therapeutic approach in stroke therapy. As these studies are designed to examine whether EPC transplantation extends the therapeutic window of tPA for stroke, the current research builds on the their long-standing goal of translating cell therapy from the laboratory to the clinic.

"If BBB restoration via EPC transplantation alone or in combination with tPA is proven effective, the researchers believe that direct clinical application of this cell therapy could help a large population of ischemic stroke patients who may have missed the limited 3-hour tPA window," explained Dr. Paul R. Sanberg, director of USF's Center of Excellence for Aging and Brain Repair.
