The hair follicle (HF) is the biological unit responsible for producing a single hair shaft. The follicles are arranged with concentric epithelial progenitor layers surrounding the dermal core, which is the dermal papilla (DP). Classically, the development of the follicle itself can be divided into three stages: [https://www.wikipathways.org/index.php/Pathway:WP2804 Induction], Organogenesis and [https://www.wikipathways.org/index.php/Pathway:WP2840 Cytodifferentiation]. Hair follicle development is a process dependent on epithelial-mesenchymal transitions orchestrated by many signaling pathways. Here we find one of three complex regulatory pathways assembled from a text mining approach portraying the development of this key mammal-specific structure. hair follicle cell CL:0002559 Cell Ontology regulatory pathway PW:0000004 Pathway Ontology
