摘要:: The aim of this study was to overtake the mechanism of the control system in endometrial cancer cell line in vitro. Ishikawa cell (IK cell) and HEC-1 cell (HEC cell) derived from endometrial cancers were cultured with serum free medium (SFM-101). IK cell possessed Estrogen receptor (ER), Progesterone receptor (PR), Epidermal growth factor (EGF) and its receptor (EGFR). HEC cell had PR, EGF, and EGFR, however HEC cell did not keep ER. EGF stimulated the growth of IK cell, but the growth of HEC cell was not stimulated by EGF. S phase cells were increased by EGF in IK cell, but were not increased by EGF in HEC cell. The growth of IK cell was stimulated significantly by EGF and Estradiol-17 beta (E2) +EGF than control. However, E2+EGF did not stimulate the growth of IK cell than EGF significantly. Danazol (D) and D+EGF inhibited the growth of IK cell significantly than control. S phase cells were decreased by the treatment of D and D+EGF. From our results, EGF stimulated the growth of ER positive endometrial cancer cell, but EGF did not stimulate ER negative endometrial cancer cell. E2+EGF and EGF stimulated the growth of IK cell as a same. However, D inhibited the growth of IK cell that was stimulated by EGF.
