Current Research Description:

We want to uncover the mechanisms that initiate liver regeneration. Using a partial hepatectomy (PHx) model, we hypothesize that an increase in portal pressure after PHx causes shear stress, which initiates sinusoidal endothelial cells to secrete Wnts. These Wnts may then activate hepatocyte ?-catenin signaling and proliferation, thus leading to regeneration.
