Electrospinning technique, as a promising tissue engineering approach, can fabricate polymer fibrous scaffolds that satisfy requirements on the construction of extracellular matrix (ECM) of native blood vessel and promote the adhesion, proliferation, and growth of cells. In this review, we summarize the...
Keywords: poly (1,4-butylene succinate); electrospinning; biomaterials; vascular grafts; bile ducts; tissue engineering 1. Introduction The exploration of materials used to fabricate novel scaffolds for tissue engineering never stops. The scaffold is a tridimensional structure that should guide cell ...
The electrospun fiber matrices based on regenerated fibroin modified by cross-linking with genipin in water–alcohol solutions were shown to promote cell adhesion, spreading, and growth and, therefore, could hold promise for tissue engineering. Keywords: silk fibroin; electrospinning; fibrous matrices; ...
