Vascular smooth muscle cell development and disease
My group studies vascular development and vascular diseases such as aortic aneurysms and atherosclerosis. We have established new methods for generating human vascular smooth muscle cells (SMC) that originate from specific embryonic lineages, using directed differentiation of human embryonic and induced pluripotent stem cells (hESC & hiPSC).
Most recently, we have established an in vitro model for generating ESC-derived epicardium which we then use to generate ‘coronary’-like SMCs. We use these and other systems to study the molecular mechanisms that regulate vascular development. Using patient-derived iPSCs we also model genetic vascular diseases in which smooth muscle cells (SMC) are implicated, e.g. Marfan syndrome (FBN1).
