The extent of TdT-mediated dUTP biotin nick end labeling (TUNEL) staining was assessed for whether apoptosis was involved in this liver damage. (a) It was overexpressed in the DEX group compared with the vehicle group, but not decreased in the DEX+MEL group. (b) Semi-quantification of the TUNEL stained cells. All the results represent standard error of mean (SEM) of six animals; * p < 0.05. The letters above each represented different groups with DEX representing the prenatal dexamethasone; DEX+MEL, melatonin treatment after prenatal dexamethasone (original magnification ×400, red arrows: apoptosis).
