Abstract: BACKGROUND: Small diameter artificial vessels are urgently needed to treat coronary artery and peripheral artery diseases in clinical practice. At present, vascular tissue engineering has become the main method for preparing small diameter artificial vessels. Selecting suitable biomaterials and cell sources is the key factor for successful construction of small diameter tissue engineered vessels. 
OBJECTIVE: To observe the effect of four kinds of electrospinning membrane materials on proliferation, adhesion and differentiation of bone marrow mesenchymal stem cells into vascular smooth muscle cells. 
METHODS: Bone marrow mesenchymal stem cells were isolated and extracted from SD rats. The bone marrow mesenchymal stem cells were inoculated separately on polycaprolactone (PCL), polycaprolactone-hyaluronic acid (PCL-HA), polycaprolactone-silk-filament proteins (PCL-SF), and polycaprolactone-gelatin (PCL-GEL) electrospinning membrane materials. After 1, 3, and 7 days of culture, the cell arrangement on the material was observed under scanning electron microscope. The proliferation and adhesion of the material were observed by phalloidin staining. The mRNA expressions of CD90, Meflin, and transforming growth factor β were detected by qRT-PCR. After 7 days of induced differentiation into vascular smooth muscle cells, the mRNA expression of ɑ-smooth muscle actin on the material was detected by qRT-PCR.
RESULTS AND CONCLUSION: (1) Bone marrow mesenchymal stem cells were arranged along the fibers of the four kinds of electrospinning membranes under scanning electron microscopy. (2) Phalloidin staining showed the regular distribution of bone marrow mesenchymal stem cells on the four kinds of electrospinning membranes and parallel distribution along the fiber direction. Moreover, PCL-HA, PCL-SF, and PCL-GEL electrospinning membranes were more conducive to the proliferation and adhesion of bone marrow mesenchymal stem cells than PCL electrospinning membranes. Compared with PCL-HA and PCL-GEL electrospinning membranes, PCL-SF electrospinning membranes were more conducive to the proliferation and adhesion of bone marrow mesenchymal stem cells. (3) qRT-PCR showed that the four kinds of electrospun membrane materials could maintain the mRNA expression of CD90 and Meflin in bone marrow mesenchymal stem cells, but there was no significant difference between groups (P > 0.05). The mRNA expression of transforming growth factor β in PCL-HA, PCL-SF, and PCL-GEL groups was higher than that in PCL group on days 1 and 7 (P < 0.05), and the mRNA expression of transforming growth factor β in PCL-SF group was higher than that in the other three groups on days 3 and 7 (P < 0.05). The mRNA expression of transforming growth factor β in PCL-HA group was higher than that in PCL-GEL group on day 7 (P < 0.05). (4) qRT-PCR showed that the mRNA expression of ɑ-smooth muscle actin in PCL-SF group was higher than that in the other three groups (P < 0.05), and that in PCL-HA group was higher than that in PCL group (P < 0.05). (5) The results indicate that compared with PCL, PCL-HA and PCL-GEL electrospinning membranes, PCL-SF electrospinning membranes combined with bone marrow mesenchymal stem cells are more suitable for the preparation of small diameter tissue engineered vessels.
