OBJECTIVE: To observe the differentiation and ultrastructural changes of rat bone marrow mesenchymal stem cells (BMSCs) and adventitial fibroblasts after they were directly contacted with cultured vascular cells in vitro. Methods: BMSCs (DAPI marker) and vascular adventitial fibroblasts were mixed and cultured according to a certain ratio. BMSCs alone
