The proliferative index (PI) is shown in panel a, significant increase in PI was noticed at 24 and 48 h time points in the ALPPS group when compared with the PVL group. Panel b shows the immenohistochemical staining of Ki-67 in the ALPPS and the PVL group, Ki-67 stained cells were noticed near the portal tract area in the early time point (24 h) and dispersed all over the hepatic lobes at 48 h time point (×40)
