The 'follicular trochanter': an epithelial compartment of the human hair follicle bulge region in need of further characterization.
Recent articles on hair follicle stem cells have summarized the current state of knowledge of what has been termed the hair follicle 'bulge'. During the course of immunohistological studies aimed at characterizing the expression of selected extracellular matrix proteins in the - as yet insufficiently characterized - niche of human bulge hair follicle stem cells, we have recently come across a largely forgotten, peculiar epithelial protrusion of the outer root sheath, which was visible in only a minority of all examined hair follicles. The morphology and immunoreactivity patterns of this structure, the 'follicular trochanter', are described herein.
