The expression of COX-1 (7A) and COX-2 proteins (7C) in primary cultured rat stromal cells. The stromal cells were pre-treated with anti-estrogen ICI-182,780 and anti-progestin RU-486 at concentration of 1 μM for 1 hr, followed by stimulation with estradiol and progesterone at concentration of 100 nM for 48 h. Histograms show densitometric analysis of COX-1 and COX-2 normalized to β-actin to correct for protein loading (7B&7D). Data represents the mean ± SEM of four independent experiments. Columns with different superscripts are significantly different (p < 0.05).
