Figure 13

A schematic representation together with examples of relative gene expression patterns in the rhesus endometrium during the secretory phase [56]. A) progesterone (P) repression of estradiol (E)-dependent genes. B) autologous down-regulation of P-dependent genes e.g. fragment 10. C) P-induction of genes during the secretory phase e.g. fragment 5. D) P-induction of gene expression during the window of receptivity e.g. fragment 12, syncytin. E) a composite cascade of gene expression patterns A-D. The associated panel (B-D) for each fragment shows the relevant temporal portion of the gel following PCR analyses.
