Objective\ To promote the differentiation of cultured endothelial cells and enhance their resistance to fluid shear stress.\ Methods\ Using the mended parallel plate flow apparatus and peristalsis pump providing fluid shear stress, endothelial culture models were established in vitro with the same environment factors as steady culture. According to the increasing degree of shear stress, the experiment included:(1) Group A, exposing to the gradual increasing fluid shear stress, (2) Group B, exposing to step ...
