The effect of an LH pulse on 3H-thymidine incorporation into cultured ovaries of metestrous rats.

J J Peluso, T Durkee, M L Gruenberg.   

Abstract

The effect of an LH pulse on the rate at which 3H-thymidine is incorporated into cultured ovaries of metestrous rats was studied. In comparison to ovaries cultured with tonic LH, an LH pulse "rescued" follicles from atresia, induced thecal cell proliferation, and increased the rate at which granulosa cells enter mitosis. It is concluded that LH pulses increase follicular growth by first triggering thecal cell proliferation and then inducing mitotic divisions within the granulosa cells of both atretic and non-atretic follicles.
