Enzymhistochemical and morphometrical studies on delta 5-3 beta-hydroxysteroid dehydrogenase during the fetal and neonatal development of rat Leydig cells.


The aim of the present report was to study the course of development of rat Leydig cells from 17 fetal day (f.d.) up to 5 postnatal day (p.n.d.), with the help of enzymhistochemical reaction of delta 5-3 beta Hydroxysteroid-dehydrogenase (3 beta-HSDH). Testes were obtained from 17 to 21 days old embryos and from 1 to 5 days old offsprings. Cryostat sections… (More)
