Objective:To investigate the effects of 4’-methery-scutellarein(4-MS) on proliferation and intracellular calcium concentration in human choriocarcinoma JAR cell line. Methods:MTT assay, flow cytometry and laser scanning confocal microscopy were used to detect the effects of 4-MS on JAR cells. Results:4-MS inhibited the growth of JAR cells. Annexin Ⅴ-FITC +/PI- cells and intracellular calcium concentration were gradually increased with the increase of the dose and action time of 4-MS. There were significant differences compared with the control group. Conclusion:4-MS can inhibit the proliferation and induce apoptosis of human choriocarcinoma JAR cell line. Its mechanism is related to the increase of intracellular calcium concentration.
