TUNEL detected cell apoptosis in the ischemic penumbra of rat brain tissue. (a) Representative images of TUNEL staining in the ischemic penumbra from different groups. (b) The number of TUNEL positive cells in the ischemic penumbra was calculated. Magnification ×400. Scale bar = 20 μm. The data are presented as the means ± SEM (n = 3 per group). ^*P < 0.05 and ^**P < 0.01 compared with the Sham group, ^#P < 0.05 and ^##P < 0.01 compared with the MCAO/R group, ^&P < 0.05 and ^&&P < 0.01 compared with the MCAO/R + EA group
