This study aims to investigate the therapeutic potential of adult bone marrow stromal cells (BMSCs). Exposed to a cocktail of induction medium, some BMSCs could differentiate into cell types with phenotypes of neural lineages in vitro. These cells expressed neural markers nestin, GFAP, 68-kDa neurofilament and beta-tubulin III as detected by immunohistochemistry and RT-PCR. Fluorescence-labeled cells were injected intravenously at 72 h after traumatic brain injury. Transplanted cells survived and migrated to the ipsilateral cerebral cortex at different time points after injection. They were immunopositive for neuronal marker MAP-2, oligodendrocyte marker CNPase, astrocytic maker GFAP or microglial marker OX-42 in vivo. In rats receiving BMSC transplants, there were significant improvements in motor and neurological functions when compared with the control groups. Hence, the therapeutic potential of BMSCs for traumatic brain injury is further amplified. (C) 2005 Elsevier Ireland Ltd. All fights reserved.
