Recently, transcriptome sequencing technology has achieved significant progresses in gene network regulation of important economic traits in animals. As the derivative of mammalian skin, hair follicle is capable of self-renew. Its proliferation and differentiation result in hair formation. Researches have revealed that many growth factors and receptors coordinate genes and environment, as well as play an extremely important role during hair growth. In this review, we summarize the progresses that transcriptome sequencing technologies have achieved in researches of hair follicle development and renegeration in a variety of species, such as humans, mice, goats. We aim to provide theoretical mechanisms for the artificial interference of villus growth cycle, and new ideas for therapeutic treatment of skin hair follicle- related diseases.
