240-270 / 1000+ resultsresearch Outer root sheath keratinization in anagen and catagen of the mammalian hair follicle. A seventh distinct type of keratinization in the hair follicle: trichilemmal keratinization.
Trichilemmal keratinization is a unique process in hair follicles where the outer root sheath turns into keratin without a specific layer.
research [Nevoid bundle hairs].
Naevoid bundle hair is an unusual hair growth pattern where multiple hairs fuse together.
research Trichilemmoma.Cell biology of the normal human outer root sheath.
The outer root sheath in hair follicles changes during growth, with different keratinization processes in its layers.
research Degradation of human hair keratin scaffold implanted for repairing injured skeletal muscles.
Human hair keratin scaffolds help repair injured muscles by breaking down and activating muscle cell growth.
