Apoptotic cells in liver grafts. (A) Normal saline group; (B) HO-1 group; (C) BMMSCs group; (D) HO-1/MSCs group. (a) Histological sections from rats of four groups at each time point were subjected to the TUNEL assay (200x). (b) Histogram showing the percentage of positive apoptotic signals in each group on days 1, 7, and 14. Apoptotic cell numbers in the HO-1/MSCs group were significantly lower compared with control groups on POD 1, 7, and 14, respectively ().
