    TLDR Understanding skin stem cells and their regulation is key to improving skin healing and treating disorders.
    The review highlights the critical role of skin stem cells (SCs) in maintaining and regenerating skin tissue, emphasizing their ontogeny and molecular regulation. It discusses various SC types, including bulge SCs and interfollicular epidermal stem cells (IFESCs), and their differentiation processes influenced by molecular cues and environmental interactions. Key signaling pathways such as Wnt, Notch, and Hippo, along with transcription factors and epigenetic factors, are crucial in regulating SC behavior. Disruption of these processes can lead to skin pathologies like cancer. Understanding these mechanisms is vital for advancing regenerative medicine strategies for skin disorders and injuries, with potential therapeutic implications for dermatological conditions.
