dc.description.abstract | The ability of mature smooth muscle cells (SMCs) to modulate their phenotype in response to environmental cues is a critical issue related to vascular diseases. A tissue engineered vascular graft shall promote the contractile phenotype of vascular SMCs. To this aim, Tecophilic/gelatin (TP/gel) was electrospun at different weight ratios of TP/gelatin (100:0, 70:30, 50:50, 30:70), leading to differences in biochemical and mechanical properties of the nanofibers which in turn influenced the phenotype of SMCs. Results indicated that both the substrate with higher ligand density and lower stiffness could enhance SMC contractility and reduce cell proliferation. However, observing the highest SMCs contractility on electrospun TP(70)/gel(30) among the composite scaffolds demonstrated stiffness as the most critical parameter. Due to conflicting effects of softness versus minor fraction of gelatin (reduced ligand density) within TP(70)/gel(30) fibers, a relatively high proliferation of SMCs was still observed on TP(70)/gel(30) scaffold. The surface of TP(70)/gel(30) scaffold was further modified through physical adsorption of gelatin molecules so as to increase the ligand density on its surface, whereby a functional vascular construct that promotes the contractile behavior of SMCs with low cell proliferation was developed. © 2014 American Chemical Society. | |
