Cutaneous regeneration is a dynamic and complex process that requires a series of coordinated interactions involving epidermal cells, dermal cells, growth factors, the extracellular matrix (ECM), nerves and blood vessels at a damaged site. Mesenchymal stromal cells (MSCs) have been reported to participate in all afore-mentioned stages. Exosomes are one of the key secretory products of MSCs, resembling the effect of parental MSCs. They can shuttle various proteins, messenger RNA (mRNA) and microRNAs (miRNAs) to modulate the activity of recipient cells, and play important roles in cutaneous wound healing. Compared with MSCs, exosomes are more convenient to store and transport. Moreover, they avoid many risks associated with cell transplantation. Therefore, MSC-exosome-mediated therapy may be more safe and efficient. In this review, we summarize the latest studies and observations on the role of MSC-exosome in the acute and chronic wound model and provide a comprehensive understanding of the role of exosomes in wound healing. This review can assist investigators in exploring new therapeutic strategies for enhancing the efficacy of MSC-exosome for cutaneous repair and regeneration.
