We've been hearing much more about the multipotent stem cells found in hair follicles of late. Here, more from Medical News Today illustrates that the infrastructural and supporting work is proceeding apace: researchers "used sophisticated techniques to engraft human scalp tissue onto mice and then isolated and examined living human hair follicle stem cells. The authors identified a panel of marker proteins expressed on the surface of these elusive cells that can be used in future research to aid in their identification. They go on to note important differences between mouse and human stem cell markers. ... investigators can now readily extract and study very specific follicular cell types for the ability to regenerate hair and skin, with the hope of developing novel methods for treating skin and hair disease." Infrastructure is bland, but very important. Expect to hear more in the near future.
