Research Interests

Research in my laboratory focuses on understanding the cellular and molecular basis of cell migration during embryonic development.  The migrating pronephric (kidney) duct primordium of the axolotl embryo - a salamander - is the model system we study.  During development, cells of the kidney duct migrate along a stereotypical pathway from the anterior flank to the cloaca - the exit point for kidney filtrate and gametes.  Guidance cues telling the duct when, where and in what direction to migrate reside in surrounding embryonic tissues.  The lab is now directing its efforts toward determining the molecular identity of pronephric duct guidance cues and their receptors.  Specific techniques students use in their research include:  microsurgery, microinjection, RT-PCR, DNA sequencing, immunocytochemistry, in situ hybridization, northern and western blot analysis and protein purification.
