Abstract:

Enhanced resistance to oxidative stress makes the adipose stem cells (ASCs) able to promote wound repair and regeneration. Such cells can be achieved by addition of an anti-oxidant to the cell culture medium. In this study, a combination of Honey (H) and ASCs was applied on burn wounds and the injured area was then covered by a Tegaderm (T) dressing in a rat model. The results compared with H, T, and T-H treated groups. Wound healing was evaluated by histopathological, histomorphometrical, molecular, and biochemical assessments on days 7, 14, and 28 post-wounding. ASC-containing honey (T-H/ASC) resulted in substantial reduction in the level of pro-inflammatory cytokines including interleukin-1β (IL-1β) and transforming growth factor-β1 (TGF-β1) in the wound bed, at 7 day post surgery. H/ASCs also elevated the level of bFGF expression, indicating that ASCs enhanced angiogenesis at 7 day post-wounding. T-H/ASCs significantly improved angiogenesis, re-epithelialization, and granulation tissue formation compared to other treatment regimes, at 14 day post-surgery. These outcomes were in exceptionally good agreement with the histology and biochemical findings. Increased bFGF level in the T-H/ASCs treated wounds at the 28th day post-surgery showed the anti-scarring activity of ASCs. Therefore, honey can be considered as a protective material in maintaining the viability of ASCs and improving the cellular resistance to oxidative stress. Furthermore, combination of ASCs and honey can provide a nutrient media for the ASCs and enhance the ability of regeneration of the ASC-based therapies.
