Figure 1. EC304 reduced endometrial epithelial cell attachment to peritoneal mesothelium in vitro.

A. Estrogen and progesterone dose dependently enhanced the attachment of HESC cells to monolayers of peritoneal mesothelial (LP9) cells (*p < 0.01). B. Fluorescently labeled HESCs attach on to LP cells at 6 h. EC304 shows reduced rate of attachment (*p < 0.05). C. The percent of attached HESCs were represented as compared with corresponding progesterone treated cells.
