Kera-308 Cells

The Kera-308 cell line, established from adult mouse skin keratinocytes, offers a versatile model for studying the intricate processes of skin physiology, particularly wound healing and keratinocyte function. This cell line demonstrates a remarkable ability to up-regulate keratin expression, including wound-induced keratin types such as Krt6a, under specific conditions such as treatment with Morus alba root extract. The responsiveness of Kera-308 cells to phorbol 12-myristate 13-acetate (PMA) highlights their utility in investigating the cellular mechanisms underlying skin repair and regeneration. A standout feature of Kera-308 cells is their dose-dependent proliferation response, which can be significantly enhanced by external stimuli like Morus alba root extract. This characteristic makes Kera-308 an excellent tool for probing the molecular underpinnings of keratinocyte proliferation and differentiation in response to therapeutic agents. Moreover, the transcriptional profile of Kera-308 cells in wound healing scenarios, particularly their up-regulated keratin filament and CXCL12/CXCR4 signaling, provides invaluable insights into the cellular and molecular dynamics at play during skin repair. The involvement of these signaling pathways underscores the relevance of Kera-308 cells in exploring new therapeutic strategies for enhancing wound healing and treating skin disorders.
