Figure 5From: Involvement of cyclin B1 in progesterone-mediated cell growth inhibition, G2/M cell cycle arrest, and apoptosis in human endometrial cellApoptosis of hECs induced by progesterone and Alp. Human endometrial cells were treated with progesterone alone or in combination with Alp. Apoptosis was indexed by the detection of Annexin V. A: Apoptotic cells as labeled with Annexin V and followed by flow cytometry. B: Comparison of the proportions of apoptotic cells. The amount of apoptotic cells was significantly increased with the treatment of progesterone alone or progesterone plus ALP (*P < 0.05, **P < 0.01, compared with the control cells). There was also significant difference between treatment with progesterone alone and progesterone plus Alp (#P < 0.01).Back to article page
