Omentin attenues oxidative stress-induced down-regulation of Ⅰ/Ⅳ collagen in the human aortic smooth mnscle cells

Objective To study the influence of omentin on the expression of collagenⅠ/Ⅳin the human aortic smooth muscle cells subjected to oxidative stress.Methods Human aortic smooth muscle cells were cultured in vitro.When cell density reached above 90%,cells were randomly divided into 5 groups:control group。
