TUNEL labeling in ipsilateral striatum at 7 days after MCAO. TGF-β1 treated mice (n = 4) display less TUNEL-positive cells (B) than control groups (n = 6) following brain ischemia. Quantitative analysis showed reduction of the number of TUNEL-positive cells after intranasal administration of TGF-β1 (C). Scale bars = 20 μm. Data are presented as mean ± SEM. *P < 0.05 vs. control.
