Isoflavones have attracted much notice due to their health advantages; however, a comprehensive understanding of the effects of isoflavones on endometrium biology remains undiscovered. The expression and deficiency of leukemia inhibitory factor (LIF) and LIF receptor (LIFR) has been shown to be involved in multiple implantations failures in female infertility. Mechanisms implicated in the failure of implantations require further researches, thus our aim is to investigate the effect of the Trifblium pratense L. isoflavone extract with abundant formononetin content on implantation through assessing LIF and LIFR expressions. The Ishikawa cells were cultured with 20, 30, and 40 mu g/mL concentrations of Trifolium pratense L. isoflavone extracts for 24 h and detected staining intensity of LIF and LIFR by immunocytochemistry and immunofluorescence staining using image analysis software. As compared with the control and 20 mu g/mL pratense L. groups, the staining intensity of LIF and LIFR in 30 and 40 mu g/mL Tiafolium pratense L. groups were significantly increased (P < .0001). Our findings suggest that Tiafolium pratense L. isoflavone extract may alter the endometrium expression of LIF and LIFR in the human endometrial adenocarcinoma cell line.
