Keratinocytes, which constitute 90 % of the cells in the epidermis of the skin, have been demonstrated to communicate with other skin cells such as fibroblasts, melanocytes and immune cells through extracellular vesicles (EVs). This communication is facilitated by the enriched EV biomolecular cargo which regulates multiple biological processes within skin tissue, including cell proliferation, cell migration, anti‐apoptosis, pigmentation transfer, and extracellular matrix (ECM) remodelling. This review will provide an overview of the current literature and advances in the field of keratinocyte‐derived EV research with particular regard to the interactions and communication between keratinocytes and other skin cells, mediated by EVs and EV components. Importantly, this information may shed some light on the potential for keratinocyte‐derived EVs in future biomedical studies.
