Localization of 17βHSD2 protein in human term placentas

Copyright information:Taken from "Human type 2 17beta-hydroxysteroid dehydrogenase mRNA and protein distribution in placental villi at mid and term pregnancy"http://www.rbej.com/content/5/1/30Reproductive biology and endocrinology : RB&E 2007;5():30-30.Published online 10 Jul 2007PMCID:PMC1947994. Tissue sections of term placentas were immunostained with anti-17βHSD2 () or with pre-adsorbed antibody, as negative control (). Strong positive signals were observed in terminal villi (TV) (), more precisely in sinusoidal capillaries (Si). 17βHSD2 expression is observed in the paravascular capillary net (PC) as well as in endothelial cells (EC) forming the blood vessel walls of stem villi (SV) (). Some blood vessels are EC positive (+) and others EC negative (-).
