Experimental results proved that carboxybetaine-REDV coating maintained desirable antifouling ability and fine hemocompatibility, and was able to enhance the competitive growth of endothelial cells while limiting the adhesion, proliferation, and migration of smooth muscle cells.
Chitosan/poly (vinyl pyrollidone) coatings improve the antibacterial properties of poly(ethylene terephthalate)
Direct adhesion of endothelial cells to bioinspired poly(dopamine) coating through endogenous fibronectin and integrin α5 β1.
It is found that HUVECs can attach directly to and spread with well-organized cytoskeleton and fibrillar adhesions on the PDA surface, whereas cells adhere poorly to and barely spread on the control polycaprolactone surface.
Surface modulation of complex stiffness via layer-by-layer assembly as a facile strategy for selective cell adhesion.
This study presents an approach to enhance EC competitiveness over that of SMC through the selective EC adhesion, which is achieved by modulating a complex surface stiffness based on the technique of layer-by-layer (LbL) assembly.
