Hair growth stimulated using stem cells
A team of researchers from the University of Southern California in Los Angeles have managed to grow hair starting from stem cells, uncovering key molecular events involved in hair growth and stimulating it in adult mice.
The new research – which has been published in the journal Proceedings of the National Academy of Sciences – offers a step-by-step explanation of the process by which hair grows. The findings pave the way for hair growth stimulation in patients with alopecia or male pattern baldness.
A team of researchers set out to examine how follicles grow out of the skin and how they produce hair by using so-called organoids, which are clusters of stem cells grown in vitro that can self-organize into an organ-like structure.
They used the 3-D structure of organoids to gain a better understanding of a certain organ, as they have similar properties to the organ it imitates – which, in this case, is the human skin.
The study’s first author is Mingxing Lei, a postdoctoral researcher in the University of Southern California’s (USC) Stem Cell laboratory.
