Japanese scientists have successfully grown hair follicles in a laboratory for the first time


Japanese scientists first grew hair follicles in a laboratory, which could signal the start of a breakthrough drug for hair loss.

In a press release, researchers at Japan’s Yokohama National University said they successfully developed hair follicles in vitro increase after years of studying the factors that contribute to hair growth.

Use unique The gel they developed was able to change the architecture of the skin cells in mice by reprogramming the cells to promote hair growth, according to a study published in the journal Science Advances.

In an effort to understand the interactions between skin cells and connective tissue that lead to hair growth, Japanese scientists created “organoids”, which are “small, simplified copies of organs“. They were then reprogrammed with a gel to recreate the environment of the hair follicle.

Kairbaan Hodivala-Dilke’s medical specialist is associated with Queen Mary University of London but has not been involved in science. He said, “If you visualize a hair follicle, the hair is in the center, and around it are layers of epithelial cells and other specialized cells.”

In turn, the same gel mimics the body’s natural environment by allowing epithelial cells to crawl around each other, according to Hodival-Dilke.

According to Junja Fukada, the hair cycle in mice lasts about one month, “possibly due to the fact that the hair follicles grew up to three millimeters in the month they grew.” He continued by saying his group was currently trying to duplicate experiment using human skin cells.

Hodivala-Dilke says the discovery is early stage and “does not heal hair loss by itself.” “It lays the groundwork for anyone who has the potential to do so,” she continued.

According to a British researcher, “It may be possible to remove hair from someone who is exceptionally rich hair, induce growth in the laboratory, and then transplant using these hair follicles. ‘
