The effect of Cytl1 on the endometrial expression of LIF and HB-EGF.

<p>(<b>A</b>) Reverse -transcription PCR analysis of LIF and HB-EGF mRNA expressions in human endometrial cell lines (HEC-1-A, RL95-2) after treatment with different concentrations of Cytl1. LIF expression in the culture supernatant of HEC-1-A (<b>Ba</b>) and RL95-2 (<b>Bc</b>), and HB-EGF expression in HEC-1-A (<b>Bb</b>) and RL95-2 (<b>Bd</b>) were detected by ELISA. The standard curve prepared according to manufacturer’s instruction was used to determine sample concentrations. P, progesterone. Data represent mean±SEM. *<i>P</i> < 0.05; **<i>P</i> < 0.01.
