Ki67 expression in microglia and pericytes. Paraffin-embedded brain sections were immunostained with Iba1 for microglial cells, CD13 for pericytes, and Ki67 for cell proliferation, and subsequently counter-stained with DAPI (blue) for cell nuclei at 2 weeks after reperfusion. Several proliferating microglial cells were detected in the infarct lesion, but no proliferating pericytes were observed (inset images). Scale bar represents 10 μm. Representative images were obtained from animal R326.
