hair follicles hair cycle chemical signaling hormones growth factors keratins keratin-associated proteins melanocytes pigmentation genomic variations non-genomic variations nutrients gene expression

TLDR Hair follicle growth and fiber production in animals are influenced by chemical signals, proteins, pigmentation, genetics, and nutrients.

The paper reviewed the biology of hair follicles and fine fibre production in animals, focusing on the anatomy and behavior of follicles during the hair cycle. It highlighted the role of chemical signaling, involving hormones and growth factors, in regulating follicle development and function. The study examined the composition of follicles, including keratins and keratin-associated proteins, and their impact on fibre properties like length and diameter. It also discussed the regulation of pigmentation by melanocytes and the influence of genomic and non-genomic variations on phenotypes. Additionally, the paper considered the importance of nutrients in supporting follicular structures and gene expression.
