Interrogating the integument: the role of the epidermis in hair induction

Abstract

Hair follicle development is driven by interactions between the epithelium and underlying mesenchyme. These reciprocal interactions are essential for development, as a lack of response from either the mesenchyme or epithelium results in arrested growth. A large body of research has focused on the role of mesenchymal cells during hair follicle development and their inductive properties for hair neogenesis. In this commentary, the role of the epidermis during hair follicle induction will be discussed.

Keywords: competence; epidermis; hair induction.
