Fabrication of Chitosan Based Nanofibrous Scaffold Using Free Surface Electrospinning for Tissue Engineering Application

Nanofibrous scaffold in tissue engineering

Dear Friends, Nanofibrous scaffolds have been a major revolution in the field of tissue engineering which may improve the health and quality of life by enhancing tissue function. These are the artificial extracellular matrices which offer natural surroundings for tissue formation. Owing to their high surface to volume ratio, nanofibrous scaffolds increase cell adhesion, proliferation, and diffe...

Physiological pulsatile flow culture conditions to generate functional endothelium on a sulfated silk fibroin nanofibrous scaffold.

Many studies have demonstrated that in vitro shear stress conditioning of endothelial cell-seeded small-diameter vascular grafts can improve cell retention and function. However, the laminar flow and pulsatile flow conditions which are commonly used in vascular tissue engineering and hemodynamic studies are quite different from the actual physiological pulsatile flow which is pulsatile in natur...

A Biomimetic Silk Fibroin/Sodium Alginate Composite Scaffold for Soft Tissue Engineering

A cytocompatible porous scaffold mimicking the properties of extracellular matrices (ECMs) has great potential in promoting cellular attachment and proliferation for tissue regeneration. A biomimetic scaffold was prepared using silk fibroin (SF)/sodium alginate (SA) in which regular and uniform pore morphology can be formed through a facile freeze-dried method. The scanning electron microscopy ...
