Synthesis of bone biocompatible implants using human adipose-derived mesenchymal stem cells (hADMSCs) and PCL/laminin scaffold substrate
Objectives: Bone tissue engineering is considered a new method in the treatment of bone defects and can be an effective alternative to surgery and bone grafting. The use of adipose tissue mesenchymal stem cells (ADMSCs) on synthetic polymer scaffolds is one of the new approaches in bone tissue engineering. In this study, we aimed to investigate the effect of laminin coating on biocompatibility and osteogenic differentiation of ADMSCs seeded on polycaprolactone (PCL) scaffolds.
Materials and Methods: The morphology of the electrospun scaffold was evaluated using a scanning electron microscope (SEM). Cell proliferation and cytotoxicity were determined by MTT assay. The adipogenic and osteogenic differentiation potential of the cells was evaluated. The osteogenic differentiation of ADMSCs cultured on the PCL scaffold coated with laminin was assessed by evaluating the level of alkaline phosphatase (ALP) activity, intracellular calcium content, and expression of bone-specific genes.
Results: The results showed that the ADMSCs cultured on PCL/laminin showed enhanced osteogenic differentiation compared to those cultured on non-coated PCL or control medium (P<0.05).
Conclusion: It seems that laminin enhances the physicochemical properties and biocompatibility of PCL nanofiber scaffolds; and by modifying the surface of the scaffold, improves the differentiation of ADMSCs into osteogenic cells.
