The primary interest of my laboratory is to understand the role of signaling molecules in regulating embryonic development and adult tissue homeostasis. We have focused on the superfamily of secreted proteins that are structurally related to transforming growth factor-Β (TGF-Β). Members of this growth factor family have been shown to play important roles in regulating the development and function of many different tissues, and as a result, many of these factors have shown enormous therapeutic potential for a wide range of clinical applications. Using molecular genetic approaches, we have identified a large number of novel mammalian TGF-Β family members that we have designated growth/differentiation factors (GDFs). We have been using a variety of experimental approaches, including genetic manipulation of mice, to attempt to understand the precise biological functions of these molecules. We are particularly interested in understanding the roles of these molecules in regulating tissue growth.
