|Resumo(s):||Severe burn injuries can lead to delays in healing and devastating scar formation. Attempts have been made to develop a suitable skin substitute for the scarless healing of such skin wounds. Currently, there is no effective strategy for completely scarless healing after the thermal injuries. In our recent work, we fabricated and evaluated a 3D protein-based artificial skin made from decellularized human amniotic membrane (AM) and electrospun nanofibrous silk fibroin (ESF) in vitro. We also characterized both biophysical and cell culture investigation to establish in vitro performance of the developed bilayer scaffolds. In this report, we evaluate the appropriate utility of this fabricated bilayered artificial skin in vivo with particular emphasis on healing and scar formation due to the biochemical and biomechanical complexity of the skin. For this work, AM and AM/ESF membranes alone or seeded with adipose-tissue-derived mesenchymal stem cells (AT-MSCs) are implanted on full-thickness burn wounds in mice. The healing efficacy and scar formation are evaluated at 7, 14, and 28 days post-implantation in vivo. Our data reveal that ESF accelerates the wound-healing process through the early recruitment of inflammatory cells such as macrophages into the defective site as well as the up-regulation of angiogenic factors from the AT-MSCs and the facilitation of the remodeling phase. In vivo application of the prepared AM/ESF membrane seeded with the AT-MSCs reduces significantly the post-burn scars. The in vivo data suggest that the potential applications of the AM/ESF bilayered artificial skin may be considered a clinical translational product with stem cells to guide the scarless healing of severe burn injuries.|
