【Abstract】Objective: To investigate the inhibition of proliferation and the induction of apoptosis in vitro cultured human endometrial adenocarcinoma Ishikawa cells by docetaxel. Methods: Human endometrial adenocarcinoma Ishikawa cells were cultured in vitro and treated with different concentration of docetaxel for 48h respectively, MTT assay and flow cytometry were used to measure the effects of docetaxel on cell proliferation and cell cycle.Result: Docetaxel inhibited cell proliferation of cultured Ishikawa cells in a dose dependent manner（P＜0.05）; Docetaxel blocked the cells growth in G1-S period and increased the rates of cell apoptosis in a dose dependent manner（P＜0.05）.Conclusion: Docetaxel is effective for inhibiting the growth of endometrial adenocarcinoma Ishikawa cells. This anti-neoplastic effect may involve blocking cell cycle in G1-S period and increasing cell apoptosis.
