Abstract

Gangilosides are ubiquitous membrane components in mammalian cells and are suggested to play essential roles in cellular phenomena such as cell-cell interadion, differentiation, and signal transduction. Rat ovary contained GM3 as major gangiloside. Nn order to study GM3 distribution in the atretic follicles and its possible changes during follicular development, frozen sections were stained with spedfic monocional antibodies against eleven gangilo-series gangliosides including GM3. In the atretic follicles, Glf3 was expressed in a spatlo-temporally different manner during foilicular development, but GM1 and other gangliosides were not immunohistochemicaily detected. in atretic follicle from primary follicle stage, GM3 was expressed in all the theca cells and some granulosa cells adjacent to oocyte. In atretic follicle from secondary follicle stage, GM3 were expressed in all theca cells and granulosa cells. in atretic follicles from developing Graaflan follicle stages, GM3 was similarly expressed as in secondary follicle stage.
