Localisation of Sox17 staining in proliferative and secretory phase endometrial tissue and regulation by hormones. Within the proliferative (A) and secretory (B) endometrium, Sox17 localized to the glandular (open arrowheads) and luminal (closed arrowheads) epithelium, with staining appearing in an irregular, patchy, pattern. Smaller inset boxes show relevant IgG negative controls. Imaged at 20x magnification, scale bar = 50 μm. Treatment of endometrial luminal epithelial (ECC-1) cells with 10−8 M estrogen (estradiol)/10−7 M progesterone (medroxyprogesterone acetate) (Inline graphic, *p < 0.05) resulted in an upregulation of Sox17 protein, when compared to untreated, estradiol only (■, E) treatment groups. (C,D) Data presented as mean ± SEM, n = 5. Representative Western immunoblot shown.
