Effect of GDF-8 on hamster endometrial epithelial cells (EEC) in primary culture. (A) EEC in primary culture were treated with GDF-8 (5 μg/ml) for 36 h. The percentages of EEC and proliferating EEC were compared with untreated cells by Student's t-test (***P < 0.001). (B) LIF secretion by EEC into the culture medium was determined by ELISA. Data from GDF-8 treated samples was compared with untreated ones by Student's t-test (*P < 0.05). All experiments were repeated four times).
