Researchers from the Tokyo University of Science have successfully genetically engineered stem cells from dermal and epithelial cells that develop into fully functioning hair follicles. The bioengineered hair follicle stem cells were transplanted directly under the top layer of skin in mice models. The stem cells were able to produce hair follicles that made correct connections with tissues necessary for hair growth such as muscle fibers, nerve fibers, and the outermost layer of the skin called the epidermis. The hair follicles were also capable of regeneration via repetition of the hair cycle.
According to the researchers, their study is a huge development in the quest for the creation of organ replacement regenerative therapies. They contend that this discovery substantially contributes to the development of bioengineering technologies that will one day make hair regeneration therapy possible for hair loss caused by injury or disease.
