Grey hair could be a thing of the past thanks to this study
There could finally be a way of stopping hair from going grey. Thanks to researchers in the US, stem cells that have the unique ability to move between growth compartments in hair follicles were discovered.
Led by researchers at the NYU Grossman School of Medicine, the study observed the physically-aged hairs of mice and found that more and more stem cells became stuck after forced ageing, Wales Live reports. The study focused on cells in the skin of mice which can also be found in humans, called 'melanocyte stem cells' or McSCs.
It is inside these compartments that the McSCs are exposed to differing levels of maturity-influencing protein signals. Once stuck, the McSCs remain in the bulge and fail to mature into the transit-amplifying state and do not travel back to their original location in the germ compartment. It is here that proteins help them to regenerate into pigment cells.
