Abstract

Skin defects are among the most prevalent and serious problems worldwide; it is necessary to provide appropriate coverage in order to reduce possible mortality risk and accelerate wound healing. In this study, we have designed a series of extracellular matrix (ECM)-mimicking nanofibrous scaffolds composed of both natural (gelatin (GEL) and chitosan (CS)) and synthetic (poly(ε-caprolactone) (PCL) and poly (vinyl alcohol) (PVA)) polymers. The 3D constructs (PCL/GEL-PVA/CS) were reinforced with 5% (w/w) of platelet lysate (PL) for promoting cells viability and mobility. The physicochemical characterizations of nanofibers confirmed suitable hydrophilicity, controlled degradability, and water uptake of 250.31 ± 62.74%, and 222.425 ± 86.37% for the PCL/GEL-PVA/CS and PCL/GEL-PVA/CS + PL nanofibers, respectively. The scanning electron microscopy (SEM) images exhibited the mean diameter of the fabricated fibers (PCL/GEL-PVA/CS) in the range of 454 ± 257 nm. The blended samples (PCL/GEL-PVA/CS) were also confirmed to have higher ultimate tensile stress (UTS) (3.71 ± 0.32 MPa). From a biological point of view, the fabricated scaffolds showed appropriate blood compatibility and great potential to avoid bacterial invasion. Altogether, the tailored fabrication of PCL/GEL-PVA/CS nanofibers may be considered a suitable construct for epidermal wound healing.
