Abstract
During this study, topographic changes in healthy and atretic granulosa cells have been investigated during follicular atresia in goat ovary. Under scanning electron microscopy atresia was marked by asymmetrical shrinkage and vacuolization of cytoplasm. The specific topographical alterations observed in atretic cells were loss of micro extensions, disruption of cell-cell interaction, and smooth-textured membrane with a number of uneven depressions and ruffles. Some portions of the cell membrane were marked by extensive shrinkage due to condensation of cytosol. Irregular membrane at occasions was studded with blunt microextensions. The findings of present investigation will help in understanding the cellular changes in granulosa cells during follicular atresia and will find applications in screening of follicles for in vitro culture, in vitro fertilization and Embryo transfer technology.
