Abstract Background: Cutaneous wound healing represents a morphogenetic response to injury, and is designed to restore anatomic and physiological function. Human bone marrow mesenchymal stem cells-derived exosomes (hBM-MSCs-Ex) is a promising source for cell-free therapy and skin regeneration. Methods: In this study, we investigated the cell regeneration effects and its underlying mechanism of hBM-MSCs-Ex on cutaneous wound healing in rats. In vitro studies, we evaluated the role of hBM-MSCs-Ex in the two types of skin cells: human keratinocytes (HaCaT) and human dermal fibroblasts (HDFs) for the proliferation. For in vivo studies, we used a full-thickness skin wound model to evaluate the effects of hBM-MSCs-Ex on cutaneous wound healing in vivo. Results: The results demonstrated that hBM-MSCs-Ex promote both two types of skin cells growth effectively and accelerate the cutaneous wound healing. Interestingly, we found that hBM-MSCs-Ex significantly down-regulated TGF-β1, Smad2, Smad3, and Smad4 expression, while up-regulated TGF-β3 and Smad7 expression in the TGF-β/Smad signaling pathway. Conclusions: Our findings indicated that hBM-MSCs-Ex effectively promote the cutaneous wound healing through inhibiting the TGF-β/Smad signal pathway. The current results providing a new sight for the therapeutic strategy for the treatment of cutaneous wounds.

Abstract Background As the major interface between the body and the external environment, the skin is liable to various injuries. Skin injuries often lead to severe disability, and the exploration of promising therapeutic strategies is of great importance. Exogenous mesenchymal stem cell (MSC)-based therapy is a potential strategy due to the apparent therapeutic effects, while the underlying mechanism is still elusive. Interestingly, we observed the extensive apoptosis of exogenous bone marrow mesenchymal stem cells (BMMSCs) in a short time after transplantation in mouse skin wound healing models. Considering the roles of extracellular vesicles (EVs) in intercellular communication, we hypothesized that the numerous apoptotic bodies (ABs) released during apoptosis may partially contribute to the therapeutic effects. Methods ABs derived from MSCs were extracted, characterized, and applied in mouse skin wound healing models, and the therapeutic effects were evaluated. Then, the target cells of ABs were explored, and the effects of ABs on macrophages were investigated in vitro. Results We found ABs derived from MSCs promoted cutaneous wound healing via triggering the polarization of macrophages towards M2 phenotype. In addition, the functional converted macrophages further enhanced the migration and proliferation abilities of fibroblasts, which together facilitated the wound healing process. Conclusions Collectively, our study demonstrated that transplanted MSCs promoted cutaneous wound healing partially through releasing apoptotic bodies which could convert the macrophages towards an anti-inflammatory phenotype that plays a crucial role in the tissue repair process.
