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.
