Researchers from New York University have found the cellular 'failure' by which cells stop producing color pigments. Certain stem cells that have a unique ability to move between the growth compartments of the hair follicles, but they 'get stuck' as people age.
Hair color depends on whether the McSCs receive the signal to become mature cells that produce the protein pigments responsible for color. The new work focused on mouse skin cells, also present in humans, calledmelanocyte stem cells.
