Glossarymatrix keratinocytes

specialized cells producing keratin proteins for hair growth

Matrix keratinocytes are specialized cells located in the hair bulb at the base of the hair follicle. These cells are responsible for producing the keratin proteins that make up the hair shaft, playing a crucial role in hair growth and regeneration.
