The inherent maturity level of MSSCs becomes more complex with increasing age. As her hair grows and sheds in cycles, many of her McSCs get stuck in a specific compartment called the bulge of the follicle.

To prove the concept, the researchers created sesame-colored mice by physically pulling out their hair over and over again over a two-year period.

They found that the number of McSCs lodged in follicular bulges increased from 15% to nearly 50%. However, in young, unplucked hairs, McSCs continued to move through different compartments, picking up protein signals and consistently producing rich brown pigments.

“Multiple health problems, including cancer, will arise if stem cells are poorly regulated,” she told NPR. It’s an advantage in understanding this broader issue in medicine.”
