Abstract:

Hair follicle is a kind of micro-organ with unique structure and periodic growth,its morphogenesis begins in the embryonic stage and is induced by a series of interactions among epidermis epithelium,interstitial dermis and special derivatives. After birth,individual hair follicles begin to cycle periodically,including growth period,retrogression period and resting period. Single-cell RNA sequence(scRNA-seq)is a new sequencing method,mainly through the preparation of single cell suspension or cell groups and using the next generation sequencing to identify the gene expression information of the single cell. It is mainly used to analyze the differences of genetic and gene expression levels among cells,to better understand the specific role of a single cell in the microenvironment. The regulatory relationship between complex and rare cell populations and genes may be revealed via scRNA-seq,and the developmental trajectories of different cell lineages can be traced. This paper describes the scRNA-seq and its application in the regulation of hair follicle development,aiming to provide theoretical reference for revealing the molecular regulation mechanism of hair follicle development.

Key words: single-cell RNA sequencing, single cell isolation technique, hair follicle development
