To evaluate the [P.sub.4] production by hen granulosa cells cultured for a long-term, granulosa cells (3 x [10.sup.5] cells/well) of the [F.sub.1] and [F.sub.3] cultured for 48 h in serum-free medium were cultured for an additional 48 h with serum-free medium containing one of the following materials: oLH and oFSH at the concentrations of 0.1, 1, 10, and 100 ng/mL, respectively, and cVIP, AVT, MT, T, [E.sub.2], E, NE, PGE1, and [PGF.sub.2[alpha]] at the concentrations of [10.sup.-9], [10.sup.-8], [10.sup.-7], and [10.sup.-6] M, respectively.
To examine whether [E.sub.2] affects [P.sub.4] and T production by theca internal cells of [F.sub.1], [F.sub.2], and [F.sub.3-5], theca internal cells (2 x [10.sup.5] cells/mL/tube) were incubated for 4h with or without [E.sub.2] at the concentrations of [10.sup.-9], [10.sup.-8], [10.sup.-7], and [10.sup.-6] M and oLH (100 ng/mL) and oFSH (100 ng/mL), respectively.
Also only in [F.sub.3] granulosa cells, [P.sub.4] production was stimulated 1.46 and 1.95 fold by oFSH at the concentrations of 10 and 100 ng/mL, respectively.
En el tratamiento A ([T.sub.A], Control), las ovejas recibieron un estimulo superovulatorio con Hormona Foliculo Estimulante ovina (oFSH, ovagen[R]), utilizando 176 unidades NIH-FSH-S1 por oveja, distribuidas en ocho aplicaciones con dosis decrecientes.
Para inducir la superovulacion se le administro a cada oveja FSH ovina (oFSH; Ovagen[R], Immuno-Chemical Products Ltd; Nueva Zelanda), a intervalos de 12 h en dosis decrecientes (35,2; 35,2; 26,4; 26,4; 17,6; 17,6; 8,8; 8,8 unidades NIH-FSH-S1), iniciando 72 h antes de la retirada de las esponjas, la cual coincidio con la septima inyeccion.
En ovejas sometidas a un estimulo superovulatorio con oFSH se observo un incremento en todas las variables de respuesta evaluadas cuando se adiciono rbST (TABLA II), principalmente en tasa de ovulacion (86,52% vs 96,64%) y tasa de viabilidad embrionaria (54,69% vs 82,05%) (P<0,01).
