Attenuated infiltration of microglia/macrophage in the cortical regions of MCAo rats given NormBM-MSC Cm and IschBM-MSC Cm. (A) The illustration indicated the cortical region of the brain tissue was examined. Coronal sections of brain tissue were immunostained with anti-ED1 antibody labeled FITC. Immunofluorescent showed that ED-1 positive cells were abundant in the ischemic cortex on day 7 after MCAo (Control), whereas ED-1 positive cells were fewer in the group given NormBM-MSC Cm or IschBM-MSC Cm. ED-1 positive cells were absent in the unaffected hemisphere after MCAo. (B) The numbers of ED1 immunoreactive cells were determined using Image-Pro Plus software. Representative data were taken as the means ± S.D. of three repetitions.
