Targeted delivery of adipose-derived stem cells via acellular dermal matrix enhances wound repair in diabetic rats.
Cell-based therapeutic intervention has emerged as a new approach to accelerate wound closure. Adipose-derived stem cells (ASCs), as a fascinating cell source, have received much attention in tissue repair and regeneration. In this study we evaluated the potential of acellular dermal matrix (ADM) scaffold serving as a carrier for the delivery of ASCs and investigated its therapeutic effects on wound healing. ⋯ Immunofluorescence analysis further indicated that capillary density was evidently increased in the ASCs-ADM group compared with the control or ADM group. In addition, western blot analysis showed that ASCs-ADM significantly increased the expression of angiogenic factors, which was consistent with in vitro data. Taken together, our results suggest that targeted delivery of ASCs via ADM scaffold accelerate diabetic wound healing through a paracrine mechanism, with enhanced granulation tissue formation and increased re-epithelialization and neovascularization.
