Welcome

Blood vessels are of paramount importance to life as they transport nutrients and oxygen to organs, performing a critical role as the superhighway of the body. Blood vessels are lined by endothelial cells which act as barriers regulating exchanges between vessel lumens and surrounding tissues. A large supply of human endothelial cells would drive diverse applications, such as modeling of cardiovascular diseases and vascularizing organoids or tissues for regenerative medicine. Our goal is to generate pure populations of human artery and vein endothelial cells from embryonic and induced pluripotent stem cells.

Liver failure is the 12th leading cause of death in the U.S. Our goal is to generate pure populations of human liver cells from embryonic and induced pluripotent stem cells, thereby providing a source of liver cells for transplantation into patients-in-need. We have shown that embryonic stem cell-derived human liver progenitors can engraft the injured mouse liver, regenerate human liver tissue in vivo, and partially improve survival.
