a Representative microphotographs of terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL)-positive neurons in the left temporal cerebral cortex at 24 h after modeling. Scale bar = 50 μm. b Representative image demonstrating the location of staining (small black box). c Quantitative analysis of TUNEL-positive neurons per mm2 in the left cerebral cortex at 24 h after modeling. Data are expressed as mean ± standard deviation, (n = 4 per group). ** P < 0.01. DMSO, dimethyl sulfoxide; PBS, phosphate buffered saline; PD173074, pan-FGFR inhibitor; rFGF-2, recombinant fibroblast growth factor-2.
