Abstract

Nanofibrous composite scaffolds based on Tecophilic (TP) and gelatin (gel) were electrospun and further modification of their surfaces was performed by adsorption of gelatin or fibronectin biomolecules. The ability of coated scaffolds to alter the proliferation rate of smooth muscle cells (SMCs) was investigated via various assays and compared to cell proliferation on non-coated scaffolds. The results confirmed the potential of both coated and non-coated composite scaffolds to support SMC growth. Although, the presence of fibronectin increased the proliferation, adsorbed gelatin could reduce the proliferation of SMCs. The success of a tissue engineered vascular graft depends on the ability of the scaffold to control the proliferation rate of SMCs and thus our study provides a better insight towards the fabrication of functional constructs for vascular regeneration.
