A research group at Yokohama National University announced that it succeeded in experimenting with mice to artificially create hair outside the body.
When the hair was transplanted into the mouse, it was confirmed that it was fixed and regrown, so it is expected that it will lead to the treatment of alopecia and the like.
The research was conducted by a group led by Professor Junji Fukuda of Yokohama National University and published in the American science magazine Science Advances.
The group extracted the cells that form the surface of the fetal mouse skin and the cells that support the tissue of the body, mixed them with low concentrations of proteins that connect these cells, and cultured them.
Then, two days later, the cells that support the surface cells began to surround them, and 10 days after the start of the culture, hair containing the part called "hair follicle" that produces hair grew. is.
Furthermore, when the hair that had grown to about 5 mm was transplanted to the skin of the mouse, it was established, and although it fell out once, it was replaced by new hair after about 3 weeks.
This is the first time that we have succeeded in artificially creating hair of a certain length, including hair follicles, with almost 100% accuracy, and we believe that it will lead to the development of a treatment for alopecia. increase.
Professor Fukuda says, ``Since it can be transplanted like hair transplantation, if it can be made with human cells, it will be an epoch-making treatment.We can also reproduce how hair grows, and it can be applied to clarify the mechanism of gray hair growth.'' talking
