[Effect of pulsatile gonadotropic stimulation on the in vitro incorporation of vitellogenin by trout follicles incubated in an open perifusion system].
Rainbow Trout follicles incubated in vitro in an open perifusion system, incorporated statistically more vitellogenin after a pulsatile gonadotropic stimulation than after a perifusion without GtH. Most of the newly incorporated vitellogenin is found within the oocyte cytosol. These results demonstrate the intrinsic stimulatory effect of the "maturing" GtH on the vitellogenin incorporation.
