Objective: The purposes of the present study are as follows: 1 To study the effect of direct contact with VSMC on transdifferentiation of MSC; 2 To construct MSC of Dual-stable expression of AT2R gene medicated by tetracycline regulatable system.; 3 To investigate the effects of AT2R gene medicated by tetracycline regulatable system on neointimal hyperplasia in rat carotid arteries after balloon angioplasty.

本实验体外观察MSC与VSMC在直接接触培养下的分化情况，并以MSC为载体，通过体外细胞基因转染及筛选，获得双重稳定受到强力霉素调控表达AT2R基因的MSC，将此受到调控表达的AT2R基因导入大鼠颈动脉球囊损伤动物模型中，观察MSC细胞移植实现AT2R基因在体可调控表达在新生内膜中形成的作用及潜在意义。

①Rat MSC and VSMC were cultured and identified, respectively. MSC were labeled with DAPI firstly, and then co-cultivated with VSMC. The changes of morphology and ultrastructure of co-cultured cells were observed. Immunfluorescence analysis was performed by using monoclonal antibodies against specific antigen.②We established the regulatable system in two steps: a stable MSC line expressing rtTA has been constructed and characterized firstly by transfected with pUHD 17-1hyg and then selected by hygromycin B; in a second step, this line was used for trandfer the AT2R gene to MSC to get the well establishing double stable MSC lines;③The expression of AT2R regulated by doxycycline was evaluated by western blot;④The MSCs were transduced into rat carotid arteries with regulatable AT2R gene after the establishment of rat carotid balloon injury restenosis model. The intimal/medial area ratio were measured by digital analysis system.
