Abstract:

The hair follicle is a specific structure of mammalian skin and the organ which has a highly self-renewing ability and grows periodically for the lifetime.The development of hair follicles begins at the embryonic stage,and a series of interactions which are between epidermal and hypodermal cells induce the formation of hair follicles.The follicle will enter the periodic cycle,which contains three stages:Anagen,catagen and telogen,each of which is regulated by complex genetic networks.In recent years,great progresses have been made in the study of mammalian hair follicle development and regulation mechanisms.Some previous studies have shown that the development and circulation of hair follicles regulated by various factors,different signaling pathways and the miRNA,lncRNA and related genes,which constitute a large and complex network map.Mutual promotion and restriction between each control factor provide the necessary guarantee for the development of the hair follicle and cycle.This paper briefly describes the morphogenesis,periodic cycling and related regulatory factors of mammalian hair follicles in humans,sheep and mice in order to improve the comprehensive understanding of mammalian hair follicle development and regulation,and provide a reference and an idea for artificially controlling the cycle growth of the villus to improve the yield and quality of the villus.
