ABSTRACTElectrospinning for the formation of nanoscale diameter fibers has been explored for high performance filters and biomaterial scaffolds for vascular grafts or wound dressings. Fibers with nanoscale diameters provide benefits due to high surface area. In this study we used electrospinning for protein-based biomaterials to fabricate scaffolds from aqueous regenerated silkworm silk, Bombyx mori,. Adhesion, spreading and proliferation of human bone marrow stem cells (hBMSCs) on electrospun silk was characterized. Scanning electron microscopy (SEM) and MTT analyses demonstrated that the electrospun silk matrices promoted hBMSC attachment and proliferation over 10 days in culture. The responses of the hBMSCs on the electrospun silk matrices, combined with the biocompatibile properties of the silk fibroin protein matrix, suggest potential for use of this biomaterial as scaffolds for tissue engineering.

AbstractNanofibers could provide benefits due to high surface area for biomaterial scaffolds. In order to improve both silk fibroin and gelatin performance for potential biomedical applications, in this article the electrospinning of silk fibroin (SF)/gelatin (GT) blends with different composition ratio and concentration was performed with formic acid as a spinning solvent. The nanofibers morphologies and diameters were observed by Scanning electron microscopy (SEM). Blending with GT could improve the viscosity and spinnability of spinning solution. As-spun SF/GT blend nanofibers were more homogeneous and non-beaded than pure SF nanofibers. The diameter decreased with higher voltage at same electric field intensity. On increasing the concentrations of spinning solution, the pore diameter of nanofibers decreased, and the porosity increased. In addition, FTIR and DTA analyses showed SF/GT nanofibers had more β-sheets than pure SF nanofibers, which may be caused by an intermolecular interaction between SF and GT. Blending with GT also led to substantial enhancement in mechanical properties of SF nanofibers.

Wound dressings are high performance and high value products which can improve the regeneration of damaged skin. In these products, bioresorption and biocompatibility play a key role. The aim of this study is to provide progress in this area via nanofabrication and antimicrobial natural materials. Polyhydroxyalkanoates (PHAs) are a bio-based family of polymers that possess high biocompatibility and skin regenerative properties. In this study, a blend of poly(3-hydroxybutyrate) (P(3HB)) and poly(3-hydroxyoctanoate-co-3-hydroxy decanoate) (P(3HO-co-3HD)) was electrospun into P(3HB))/P(3HO-co-3HD) nanofibers to obtain materials with a high surface area and good handling performance. The nanofibers were then modified with silver nanoparticles (AgNPs) via the dip-coating method. The silver-containing nanofiber meshes showed good cytocompatibility and interesting immunomodulatory properties in vitro, together with the capability of stimulating the human beta defensin 2 and cytokeratin expression in human keratinocytes (HaCaT cells), which makes them promising materials for wound dressing applications.
