60-90 / 1000+ resultsresearch 597 Outer root sheath is able to synthesise glycogen from lactate-investigating glycogen metabolism in human hair follicles
research Exogen involves gradual release of the hair club fibre in the vibrissa follicle model
Hair sheds gradually from the follicle, with readiness to shed indicated by less attachment material.
research Formation of surface membranes in developing mammalian hair fibres
Mature hair surfaces are formed by keratinized cells with developed layers, not just modified plasma membranes.
research Disorders of the skin appendages
The document concludes that proper recognition and treatment of skin appendage disorders are important for management.
research Patterns of expression of trichocytic and epithelial cytokeratins in mammalian tissues II. Concomitant and mutually exclusive synthesis of trichocytic and epithelial cytokeratins in diverse human and bovine tissues (hair follicle, nail bed and matrix, lingual papilla, thymic reticulum)
Trichocytic cytokeratins are found in hair, nails, tongue, and thymus cells, showing complex regulation in tissue development.
