Fig. 8. IGF1 reduced apoptosis caused by MEHP exposure in vitro. CGCs were pre-treated with 100 ng/mL IGF1 for 2 h, and then treated with 250 µM MEHP for 24h. (A) Representative photomicrographs show TUNEL positive cells in the four indicated exposure groups. (B) The corresponding graph shows percentage of TUNEL positive cells in the four groups. Scale bar=25 µm, ^*p<0.05 vs control, ^#p<0.05 vs MEHP only treatment (n=4).
