ELISA detection showed that the expression of LIF in the co-culture group of oviduct mucosal cells and endometrial cells (experimental group 1) was also significantly higher than that in the simple oviduct mucosal cells group (control group), P < 0.05, the expression of LIF in the co-culture group (experimental groups 2 and 3) (1:0.5 and 1: 0.1) was also higher than that in the control group, but P > 0.05, the difference was not statistically significant. TE: tubal mucosal cell and endometrial cell; TS: tubular mucosal cells single.
