In another research, Nano fiber scaffolds were prepared based on polycaprolactone (PCL)-chitosan- polyvinyl alcohol for the Tissue Engineering. In this study, Nano fiber scaffolds were electrospinnedby the composite of polycaprolactone (PCL)-chitosan- polyvinylalcohol with ratio of 1.2 and 1.5. Fibroblast cells were properly indicted necessary broadening and adherence on scaffolds. Due to random orientation of Nano fibers, cells expanded as appropriately as possible in all directions. Macroscopic evaluation of clinical results indicates the favorable effect of Nano fiber scaffolds on healing incisional wound in such a way that scaffolds with cells, in the fifteenth day after the operation, heals skin as properly as possible and without leaving no scars [17].
