In our laboratory, we focus on the Eph/ephrin signaling system, and specifically how the ephrinB transmembrane ligands for Eph receptor tyrosine kinases send signals affecting cell-cell junctions and cell movement. This signaling intersects with the Wnt/PCP (Planar Cell Polarity) pathway to affect morphogenesis during development and has been shown to play an instructive role in angiogenesis, as well as tumor cell invasion.
