The study developed pluripotent stem cell-derived epidermal organoids (iEpiOs) that closely mimic in vivo epidermal structures and produce extracellular vesicles (EVs) with enhanced regenerative abilities. These iEpiOs, cultured in a 3D environment, exhibit stratified epidermal layers and maintain their characteristics through multiple passages. The research demonstrated that EVs from iEpiOs significantly enhance wound healing in vitro and in vivo, likely due to their enriched content of growth factors and specific miRNAs. The findings suggest that iEpiOs and their EVs hold promise for therapeutic applications in skin regeneration and wound healing, offering a potential alternative to animal models.
