We investigate some of the mechanisms responsible for the normal production of reproductive cells in the ovary. Despite significant advances in the study of oogenesis, there are major gaps in our understanding of how mammalian meiosis is regulated by signaling systems. Normal oocyte maturation is necessary for the production of viable eggs and embryos. We are identifying and studying the combination of interacting proteins that are responsible for initiating and regulating oocyte maturation. Clarifying the signaling pathways and protein interactions will enhance our understanding of mammalian oogenesis and provide fundamental information about cell division.
