PHA decreased CD68⁺ cells in the peri-infarct region.

<p>A: An image of cresyl violet-stained coronal section shows the areas used for cell-quantification (top, squared regions, scale bar: 1 mm) and an image of CD68 antibody-stained section shows the infarct border (bottom, white dotted line, scale bar: 50 um). P.I.: peri-infarct region. B: Representative images show the CD68⁺ cells in the peri-infarct region. The nuclei were counterstained with 4',6-diamidino-2-phenylindole (DAPI). C: Bar graph shows the percentage of CD68⁺ cells among total cells (DAPI positive nuclei) in the peri-infarct region. *: p = 0.001, #: p<0.001 vs. saline group 3 days after pMCAO; &: p<0.001 vs. saline group 14 days after pMCAO.
