From: Metformin ameliorates maternal high-fat diet-induced maternal dysbiosis and fetal liver apoptosis
Proportions of apoptotic cells in the maternal liver and ileal villi among different groups. (a) TUNEL staining in the liver and (b) ileal tissues. TUNEL staining was the strongest in the HFD group. Semi-quantitative analysis of TUNEL-stained cells in (c) liver and (d) ileal villi is shown. NCD: normal-chow diet, HFD: high-fat diet, HFMf: high-fat diet co-treated with metformin during pregnancy (n = 6), * P < 0.05
