Research Summary

The long-term research goal of the Wang laboratory is to understand the molecular mechanisms that regulate cardiovascular and hematopoietic differentiation of pluripotent stem cells (PSCs), including embryonic stem (ES) cells and induced-pluripotent stem (iPS) cells. Pluripotent stem cells hold great potential for regenerative medicine, and gene therapy. Defining the molecular links between differentiation outcomes will provide important information for designing rational methods of stem cell manipulation.  


The Wang lab focuses on the signals that direct the differentiation of pluripotent stem cells, including embryonic stem cells and induced-pluripotent stem (iPS) cells, into hematopoietic and cardiovascular cells. Pluripotent stem cells hold great potential for regenerative medicine. A significant effort in the lab is underway to generate hematopoietic cells, such as megakaryocytes and platelets, from human iPS cells. Recently, Wang's team established a system to characterize the common precursors of hematopoietic and endothelial cells (hemangioblast or hemogenic endothelial cells) in human pluripotent stem cells. By transplanting endothelial cells derived from human pluripotent cells into immunodeficient mice, his researcher team showed these cells form functional blood vessels. Therefore, it is possible that endothelial cells from patient specific iPS cells could provide a cellular source for vascular regeneration in ischemic tissue. The team also investigates the niche function of endothelial cells in regulating cardiomyocyte development from pluripotent stem cells.
