Research in the Kidder lab is aimed at understanding the roles of intercellular communication in mammalian gametogenesis. We are interested in the direct exchange of molecules via gap junction channels as well as signaling via secreted paracrine factors, and the interaction between these two modes of intercellular communication. We use a range of approaches in cellular and molecular biology and genetics to study gametogenesis in mice. We also model human connexin mutations in mice to study their effects on reproductive and other organs.
