Snippet from the article:
A hair-raising trick may lead to better hair transplants. Engineered hair follicles patched into skin can be coaxed to connect to surrounding tissue and to grow hair in an organized way, a study in mice finds.
Unlike current hair transplant methods, which simply move existing hair follicles from one area of the scalp to another to cover a bald region, the approach would spur the creation of new hair follicles from existing cells.

Progress moves slowly and consistent in the direction of solutions that will eventually allow doctors to produce the entire hair organ, essentially producing new hair. These articles are very exciting. To quote from the Nature Communications article: “Concepts in current regenerative therapy include stem cell transplantation and two-dimensional uniform cell sheet technologies, both of which have the potential to restore partially lost tissue or organ function” such as hair. The article demonstrates “fully functional orthotopic hair regeneration via the intracutaneous transplantation of bioengineered hair follicle germ” (i.e. stem cells).
In the discussion, the author Koh-ei Toyoshima et. al. states: “In this study, we successfully demonstrate fully functional bioengineered hair follicle regeneration that produces follicles that can repeat the hair cycle, connect properly with surrounding skin tissues and achieve piloerection. This regeneration occurs through the rearrangement of various follicular stem cells and their niches. These findings significantly advance the technological development of bioengineered hair follicle regenerative therapy.”
