Research Interests

My research interests center on the general question as to how extracellular cues influence cell differentiation during early embryonic development. Specifically, we study differentiation of the neural crest, which is a transient population of cells that segregate from the neural epithelium as the neural tube closes, migrate extensively throughout the embryo, and differentiate into a wide variety of derivatives. These include neurons and glia of the peripheral nervous system, melanocytes of the skin, adrenal chromaffin cells, as well as cranial and cardiac connective tissue structures. Growth factors can have profound effects on neural crest differentiation, and we are currently using a mutant mouse model to examine the role of one growth factor, platelet-derived growth factor (PDGF), in behavior of the crest cells that contribute to mesenchyme (early connective tissue) of the developing face and heart. This mouse, Patch, carries a deletion of one of the receptors for PDGF and exhibits craniofacial and cardiac abnormalities that may result from aberrant neural crest development, including defects in cell migration, extracellular matrix deposition, and/or tissue remodeling. We are examining these aspects of normal and mutant cell behavior in vitro and in vivo, urging a variety of morphological and molecular approaches. Not only do these studies contribute to our understanding of specific aspects of vertebrate development, but they also shed light on cell behaviors underlying particular human birth defects.
