Abstract: We and others have reported that mouse embryonic testes contain a subpopulation of somatic cells expressing estrogen receptor alpha (ERalpha). In order to provide evidence for a possible direct estrogen effect on mammalian testes from the early stage of their differentiation, here we devised a method for the in vitro culture of the ERalpha-expressing cells from 12.5 days post coitum mouse testes and their transfection with plasmids containing the classical estrogen responsive element (ERE) or the alternative estrogen AP-1 responsive element ups...
