TLDR Keratin K6irs is a marker for the inner root sheath of hair follicles in mice and humans.
The study identified a new keratin, K6irs, which served as a specific histological marker for the inner root sheath of hair follicles in both mice and humans. This discovery was significant as it provided a potential candidate gene for investigating inherited structural hair defects, including conditions like loose anagen syndrome.
