Adipose Derived Stem Cell‐Conditioned Media As Alternative of Stem Cell Therapy for Diabetic Wound Healing

Abstract

Diabetes mellitus (DM) is a set of metabolic disorder primarily characterized by chronic hyperglycaemia state, which is linked with several complications including retinopathy, neuropathy, and delayed wound healing. Adipose derived stem cells conditioned media (ADSCs-CM) contains several cytokines, and growth factors that can be used for treatment of diabetes-associated wounds. This study was conducted to explore the therapeutic potential of ADSCs- CM in excisional wound model in diabetic mice. Diabetes was induced in mice through Streptozotocin (STZ). Then, excisional wound splinting model in diabetic mice was developed. Subcutaneous injections of ADSC-CM (pure) and ADSC-CM conjugated with zinc sulphate were applied on the mice wound bed. Wound diameter, weight, and blood glucose levels of all the mice groups were measured at the start and end of the experiment. Additionally, qPCR was performed to analyse the expression level of some crucial genes (MMP-2, NANOG and OCT4) associated with wound healing. Overall, the results showed reduced wound size, blood glucose level, and weight restoration in ADSCs-CM treated mice as compared with control groups. Furthermore, ADSCs-CM also modulated the gene expression of MMP-2, NANOG, and OCT4, contributing to the enhanced wound healing observed in diabetic mice. This suggests ADSC-CM’s potential as an alternative therapeutic option for achieving improved wound healing outcomes in diabetic patients.
