Silk-based electrospun tubular scaffolds for tissue-engineered vascular grafts.
Electrospinning was used to fabricate non-woven nanofibrous tubular scaffolds from Bombyx mori silk fibroin using an all aqueous process. Cell studies and mechanical characterization tests were performed on the electrospun silk tubes to assess the viability of their usage in bioengineering small-diameter vascular grafts. Human endothelial cells and smooth muscle cells were successfully cultured...
متن کاملTissue engineering of small diameter vascular grafts.
Tissue engineering, using either polymer or biological based scaffolds, represents the newest approach to overcoming limitations of small diameter prosthetic vascular grafts. Their disadvantages include thromboembolism and thrombosis, anticoagulant related haemorrhage, compliance mismatch, neointimal hyperplasia, as well as aneurysm formation. This current review represents an overview about pr...
متن کامل1H MRI study of small-diameter silk vascular grafts in water
Small-diameter vascular grafts (VG) made from silk fibroin (SF) fibers by a double-raschel knitting method were prepared by coating their interior and exterior with different materials, such as SF or polyurethane (PU). The 1H spin density, 1H spin–spin relaxation time (T2) and diffusion coefficient (D) of the water molecules in the layer of the VG coated by these materials were non-destructivel...

متن کاملPolymer scaffolds for small-diameter vascular tissue engineering.
To better engineer small-diameter blood vessels, a few types of novel scaffolds were fabricated from biodegradable poly(L-lactic acid) (PLLA) by means of thermally induced phase separation (TIPS) techniques. By utilizing the differences in thermal conductivities of the mold materials, the scaffolds with oriented gradient microtubular structures in axial or radial direction were created using be...
