We explored the comparative effects of minocycline treatment and intrastriatal BMMC transplantation after experimental striatal stroke in adult rats. Male Wistar adult rats were divided as follows: saline-treated , minocycline-treated , and BMMC-transplanted animals. Animals received intrastriatal microinjections of 80 pmol of endothelin-1 ET-1. Behavioral tests were performed at 1, 3, and 7 days postischemia. Animals were treated with minocycline 50 mg-kg, i.p. or intrastriatal transplants of 106 BMMCs at 24 h postischemia. Animals were perfused at 7 days after ischemic induction. Coronal sections were stained with cresyl violet for gross histopathological analysis and immunolabeled for the identification of neuronal bodies NeuN, activated microglia-macrophages ED1, and apoptotic cells active caspase-3. BMMC transplantation and minocycline reduced the number of ED1+ cells , ANOVA-Tukey, but BMMC afforded better results. Both treatments afforded comparable levels of neuronal preservation compared to control . BMMC transplantation induced a higher decrease in the number of apoptotic cells compared to control and minocycline treatment. Both therapeutic approaches improved functional recovery in ischemic animals. The results suggest that BMMC transplantation is more effective in modulating microglial activation and reducing apoptotic cell death than minocycline, although both treatments are equally efficacious on improving neuronal preservation.
