动脉平滑肌细胞 (smooth m uscle cell,SMC)是动脉粥样硬化 (atherosclerosis,AS)斑块中的主要细胞 ,它的增殖在AS形成过程中极其重要 ,利用体外培养的人主动脉 SMC,观察了天然高密度脂蛋白 (native high density lipoprotein,N - HDL )及氧化修饰 HDL (oxidized HDL ,OX- HDL Smooth muscle cell (SMC) is a major cell in atherosclerosis (AS) plaque. Its proliferation plays an important role in the process of AS formation. Using the cultured human aortic SMC, Native high density lipoprotein (N - HDL) and oxidized HDL (OX - HDL)
