Enhancement of Endometrial Receptivity by Cnidium officinale through Expressing LIF and Integrins

Abstract EN

Improvement of endometrial receptivity is necessary for successful embryo implantation, and its impairment is associated with female infertility.

In this study, we investigated the effect of the roots of Cnidium officinale Makino (CoM) on endometrial receptivity in both in vitro and in vivo model of embryo implantation.

We found that CoM enhanced the adhesion of JAr cells to Ishikawa cells by stimulating expression of leukemia inhibitory factor (LIF) and integrins.

In addition, blocking of LIFR using hLA or neutralization of integrins αV, β3, and β5 using antibodies significantly reduced the enhanced adhesion between JAr cell and CoM-treated Ishikawa cells, indicating that LIF and integrin play an important role in trophoblast-endometrium adhesion for embryo implantation.

Furthermore, we identified that CoM significantly improved the implantation rate of blastocysts in the mouse model of RU-induced implantation failure.

By collecting these results, here, we suggest that CoM has a therapeutic potential against female infertility associated with decreased endometrial receptivity.
