Phenotype of microglia/macrophage alternative activation at four weeks after stroke. A. Double immunostaining shows expression of YM1 in microglia/macrophage (OX-42). Scale bars = 50. DAPI was used to show nuclei. B. Western blot analysis for protein level of YM1. **P <0.01 versus V-C and Mino-C. ***P <0.001 versus V-C and Mino-C. #
P <0.05 versus V-I. n = 8 in the vehicle group, 9 in the minocycline group.
