    TLDR Wounded skin cells can revert to stem cells and help heal.
    The study concluded that wounding induced the dedifferentiation of epidermal Gata6+ cells, leading them to acquire stem cell properties, which was significant for regenerative medicine and wound healing. Researchers used mouse models and various genetic and molecular techniques to show that Gata6+ cells, typically found in sebaceous ducts, migrated to the interfollicular epidermis during wound healing, where they dedifferentiated and exhibited long-term self-renewal and multi-lineage differentiation potential. This dedifferentiation was observed up to 124 days post-wounding and suggested that terminally differentiated epidermal cells could revert to a more primitive state, contributing to wound repair.
