The present invention relates to techniques for constructing and culturing
hair follicle-like organs for use in hair
drug screening methods and in the production of hair graft materials. More specifically, in the present invention, hair follicles are isolated from existing
skin organoid derived from
human induced pluripotent stem cells and cultured on a culture insert coated with collagen and
Matrigel to observe the growth and degradation of hair follicles.
Transplanting the cultured hair follicles into the
skin allows new hair to grow, demonstrating the potential use of the
hair follicle organoid as a
hair transplant material. According to treatment of
hair follicle-like organs with
hair loss inducing factors, it is observed that the hair
follicle length is shortened,
hair papilla cell aggregates are damaged, the expression of WNT3A or beta-
catenin is reduced, and the expression of DKK-1 or TGF-beta2 is increased, so that a
hair loss simulation model is established. Through observation, the organ is expected to be widely applied, such as a
screening method of a
hair growth promoter, a
hair loss prevention agent, a hair loss alleviator or a hair loss treatment agent, and a
screening method of a cosmetic composition for promoting
hair growth, preventing hair loss or alleviating hair loss.
