血管平滑肌细胞 (Ｖａｓｃｕｌａｒｓｍｏｏｔｈｍｕｓｃｌｅｃｅｌｌ,ＶＳＭＣ)存在于血管壁中膜 ,它是决定血管活性、血管构型及维持血管张力的重要因素。根据其结构和功能的不同 ,ＶＳＭＣ可分为收缩型和合成型两种表型。收缩型ＶＳＭＣ呈分化状态 ,不能增殖 ;合成型ＶＳＭ
Vascularsmooth muscle cells (VSMCs) are present in the tunica intima and are important factors in determining vasoactivity, vascular architecture and maintaining vascular tone. According to its structure and function of different VSMC can be divided into two types of contraction and synthesis. Shrink VSMC was differentiated, can not proliferate; synthetic VSM
