These MSCs show a contributory role within a paracrine manner mediating via secreted development factors, cytokines, and exosomes (Phinney and Pittenger, 2017). One of several previously published research quoted that MSC-mediated paracrine secretion promotes wound healing (Kourembanas, 2015). The benefit of employing exosomes over cell-based therapies is that these vesicles could overcome the unwanted side effects related with cell transplantation such as immune rejection. Pathogenesis of bacteria-associated DFUs is contributed by poor innervation and vascularization and chronic inflammation. In a recent study, it was observed that exosomes derived from MSCs inhibit M1 polarization and simultaneously market M2 polarization that aids inside the reduction from the inflammation (Cao et al., 2017). It is also discovered that these exosomes promote skin wound healing mediated by the regulation of M2 polarization (Cao et al., 2017). This dual nature of exosomes, i.e., anti-inflammatory and skin wound healing, is often explored in bacteria-associated DFUs. Tailored MSC-derived exosomes possess promising result in the remedy of DFUs and diabetic wounds. Inside a recent study, exosomes derived following pre-treatment of MSCs with salidroside (glucoside of tyrosol) showed healing of diabetic wounds (Ariyanti et al., 2019). Similarly, fluoxetine and pretreated MSC exosomes managed diabetic neuropathy effectively (Abdelrahman et al., 2018). It has been proved that these exosomes occupy the class of paracrine factor that mediates the therapeutic, tissue repair, and wound healing effects of MSCs (Joo et al., 2020). A number of clinical trials showed the efficacy of BMSCs within the remedy of diabetic wound and ulcers (Table 1). In an additional study, tailored exosomes derived from pretreated BMSCs with atorvastatin (ATV) showed an acceleration in the healing of diabetic wound each in.
