Abstract
AbstractThe epidermis is a stratified squamous epithelium distributed in the outermost layer of the skin and is intimately involved in the formation of a physical barrier to pathogens. Basal keratinocytes possess the properties of stem cells and play an essential role in epidermal development and skin damage recovery. Therefore, understanding the molecular mechanism of how basal keratinocytes participate in epidermal development and stratification is vital for preventing and treating skin lesions. During epidermal morphogenesis, the symmetric division of basal keratinocytes contributes to the extension of skin tissues, while their asymmetric division and migration facilitate epidermal stratification. In this review, we summarize the process of epidermal stratification and illustrate the molecular mechanisms underlying epidermal morphogenesis. Furthermore, we discuss the coordination of multiple signaling pathways and transcription factors in epidermal stratification, together with the roles of cell polarity and cell dynamics during the process.
