it is not surprising that it has well‐developed innate immunity. What we find surprising is that
the CD 49f+/CD 34+ hair follicle stem cells should have an enriched expression profile of so
many genes involved in innate immunity. Do these stem cells require extra protection from
environmental insults? Or, could there be a new role for these genes? To probe these
questions, we first summarize the roles of some key players in epidermal innate immunity …
