From: Tight Junction barriers in human hair follicles – role of claudin-1
Localization of Cldn-1 and TJ barrier in human club hair follicles. Immunohistochemical stainings of Cldn-1 (green; a,c,c′,d,f,f′) and Biotin-SH (red; b,b′,c,c′,e,e′,f,f′) in the central part and around the brush of a club hair. (c,c′,f,f′) overlay of Cldn-1, Biotin-SH and phase contrast. (b′,c′,e′ and f′) represent magnifications of (b,c,e, and f) (which are rotated for 90°) showing that Biotin-SH permeation stops at the keratinized club. Scale bars: 20 µm.
