Vega Blanco, María Margarita; Devoto, Luigi; Castro, Olga; Kohen Skop, Paulina (1994)To assess the role of estradiol (E2) upon progesterone (P4) synthesis, a well defined human midluteal cell system was used. A dose-dependent inhibition of P4 synthesis with and without hCG was induced by E2. In addition, ...

Sierralta, Walter; Kohen Skop, Paulina; Castro, Olga; Muñoz Gallardo, Alex; Strauss III, Jerom F.; Devoto, Luigi (ELSEVIER IRELAND LTD, 2005-10-20)The distribution of the steroidogenic acute regulatory protein (StAR) inside thecal and granulosa-lutein cells of human corpus luteum 9 (CL) was assessed by immunoelectron microscopy. We found greater levels of StAR ...
