Abstract (original English)

Aim Inflammatory and oxidative microenvironment at diabetic' wound site hinder the therapeutic efficacy of cell-based therapies in diabetic patients. The purpose of this study is to explore the competence of curcumin preconditioned human adipose derived cells (hASCs) in combination with platelet rich plasma (PRP) for the repair of wounds in diabetic rats. Main methods The cytoprotective effect of curcumin preconditioning for hASCs against hyperglycemic stress was evaluated through analysis of cell morphology, viability, cytotoxicity, senescence, and scratch wound healing assays. Subsequently, the healing capacity of curcumin preconditioned hASCs (Cur-hASCs) added to PRP was examined in excisional wounded diabetic rat model. Healed skin biopsies were excised to analyze gene and protein expression of wound healing markers by qPCR and western blotting. Histopathological changes were observed through hematoxylin and eosin staining. Key findings We found that Cur-hASCs counteract the glucose stress much better than non-preconditioned hASCs by maintaining their cellular morphology and viability as well as metabolic potential. Further in vivo results revealed that, Cur-hASCs co-injected with PRP resulted in faster wound closure, improved fibroblast proliferation, increased neovascularization, marked reduction in inflammatory cells, and compact extracellular matrix with completely cove
