My research focuses on understanding how Flt-1 (VEGFR-1) regulates VEGF signaling during different phases of blood vessel branching morphogenesis. I use a combination of in vitro and in vivo models to manipulate Flt-1 expression and activity to understand how Flt-1 contributes to endothelial heterogeneity that is essential for these unique stages of blood vessel development.
