[Bone marrow mesenchymal stem cell transplantation aggravates postangioplasty aortic restenosis in rats].

Objective: To observe the effect of bone marrow mesenchymal stem cell transplantation on postangioplasty aortic restenosis in rats.

Methods: 48 SD rats were randomly divided into normal control group, balloon injury group, balloon injury and MSCs transplantation group. MSCs were pre-labeled by DAPI (25 microg/ml) and then infused into aorta through the balloon catheter (MSCs 2 x 10(6)/animal).
