title: Role of reconstituted basement membrane in human granulosa cell culture.
abstract: The effects of Matrigel, a reconstituted basement membrane, on human granulosa cells were investigated. Cells were obtained from follicular aspirate in the course of oocyte retrieval for in vitro fertilization and were cultured on either a surface coated with Matrigel or uncoated plastic. Light and electron microscopy showed that granulosa cells cultured on Matrigel demonstrated three-dimensional aggregated cells with well differentiated morphology: numerous lipid droplets, microvilli, junctional complexes and lumen-like structures were seen. In contrast, cells cultured on plastic were flattened, poorly differentiated and showed apoptotic cells. Immunocytochemistry showed that the proportion of immunopositive cells for 3beta-hydroxysteroid dehydrogenase was increased in cultures on Matrigel. The results of the present study suggest that culture on Matrigel promotes the differentiation of human granulosa cells and provides a useful tool which may improve the efficiency of in vitro fertilization.
