From: Tg737 signaling is required for hypoxia-enhanced invasion and migration of hepatoma cells
(A) Representative dot plots showing the effects of low-serum medium under normoxic or hypoxic conditions on HepG2 and MHCC97-H cell apoptosis. The cultured cells were treated for the indicated time periods and then stained with FITC-conjugated Annexin V and PI. (B) The percentage of viable cells in each group is reflected in the column chart. I: cells incubated with medium supplemented with 10% FBS under normoxia; II: cells incubated with medium supplemented with 1% FBS under normoxia; III: cells incubated with medium supplemented with 1% FBS under hypoxia.
