PG - 1029-35 AB - OBJECTIVE: To examine matrix metalloproteinase-3 (MMP-3) expression in human stromal cell culture after P stimulation and the effect of conditioned medium from human embryo-epithelial cells coculture on its expression and activity. DESIGN: Metabolic and endocrine studies on human tissue. SETTING: In vitro fertilization (i.v.f.) unit and endocrine research unit. PATIENT(S): Infertile patients undergoing endometrial tissue sampling for dating at the luteal phase before i.v.f. INTERVENTION(S): Endometrial sampling and collection of human embryos culture media. MAIN OUTCOME MEASURE(S): Expression and activity of secreted MMP-3 by P-induced stromal cells, and in stromal cells exposed to conditioned medium from embryo-epithelial cell coculture. RESULT(S): Expression and activity of MMP-3 in human stromal cells decrease after P induction. Following incubation of these stromal-derived decidual cells with conditioned medium from embryo-epithelial cell coculture, MMP-3 expression and activity increased in a statistically significant manner. CONCLUSION(S): Progesterone inhibition of MMP-3 expression and its support of endometrial integrity were prevented by local expression of MMP-3 in response to embryonic signaling.
