Epithelial cell proliferation and apoptosis. Provided are scatter plots showing epithelial cell (a) proliferation and (b) apoptosis in acute acalculous cholecystitis (AAX), acute calculous cholecystitis (AXX) and normal gallbladder. In each group, cases with a high hypoxia-inducible factor (HIF)-1α expression are shown with solid circles and those with low HIF-1α expression with open circles. Line indicates the median for each group.
