Stem cells induce the natural hair growth cycle in hairless mice

Researchers lead by Professor Takashi Tsuji from the Tokyo University of Science have successfully induced the natural hair growth and loss cycle in previously hairless mice. They have achieved this feat through the implantation of bioengineered hair follicles recreated from adult-tissue derived stem cells. While these results offer new hope for curing baldness, the work has broader implications, demonstrating the potential of using adult somatic stem cells for the bioengineering of organs for regenerative therapies…

Far more importantly, the implanted follicle germs developed all the proper structures and formed correct connections with the surrounding host tissues, including epidermis, arrector pili muscle and nerve fibers. Also, the stem and progenitor cells along with their niches were recreated in the bioengineered follicles, making a continuous hair-growth cycle possible.

The method has been shown to work with all types of hair follicles, regardless of function, structure and color (depending on the type of the origin follicle). In fact, some features of the hair shaft, such as pigmentation, may be controlled – fancy a new permanent hair color?

I admit it. I chose this article to post because I think the wee mouse is cute – with his silly hair.
