Mesenchymal stem cellular adhesion and cytotoxicity study of random biopolyester scaffolds for tissue engineering.
Mesenchymal stem cells (MSCs) were isolated from the bone marrow of rabbits and inoculated respectively on 3D scaffolds of poly(3-Hydroxybutyrate-co-3-Hydroxyvalerate) (PHBV), poly(butylenes succinate) (PBS) and different blends (100/0, 80/20, 50/50, 20/80, 0/100) (Wt%) in vitro. It was found that the (50/50) blends possessed the best performance on adhesion and cytotoxicity of MSCs. The scanning electronic microscopy (SEM) results showed that the (50/50) blends had the appropriate roughness for MSCs to attach and grow, which may be used as a suitable biomaterial to create small caliber vascular grafts.
