title: Stem cell transplantation as a therapeutic strategy for traumatic brain injury.
abstract: Stem cell transplantation has enormous potential to be a viable therapeutic approach to replace the lost tissue/cells following traumatic brain injury (TBI). Several types of cell lines such as immortalized progenitors cells, embryonic rodent and human stem cells and bone marrow-derived cells have been successfully transplanted in experimental models of TBI, resulting in reduced neurobehavioral deficits and attenuation of histological damage. To date, it remains unclear whether stem cell are effective following transplantation into the injured brain via either cell replacement, trophic support, or manipulation of the local environment to stimulate endogenous neuroprotection/regeneration. This paper will review the most current and exciting pre-clinical data regarding the utility of cellular transplantation in experimental models of TBI. We believe that further work must continue to better understand the interaction between the host and the transplanted cells as well as the mechanisms regulating their differentiation into mature and functionally active neurons/glia.
