Phenotype modulation of VSMCs on patterned substrate

ABSTRACT: Loss of contractility and acquisition of an epithelial phenotype of vascular smooth muscle cells (VSMCs) are key events in proliferative vascular pathologies such as atherosclerosis and post-angioplastic restenosis. There is no proper cell culture system allowing VSMC differentiation so that it is difficult to delineate the molecular mechanism responsible for proliferative vasculopathy. We investigated whether a micro-patterned substrate could restore the contractile phenotype of VSMCs in vitro. To induce and maintain the differentiated VSMC phenotype in vitro, we introduced a micro-patterned groove substrate to modulate the morphology and function of VSMCs.
