"melanocyte"的定义和意义

What is a "melanocyte"?

A melanocyte is a specialized cell found in the skin, hair follicles, and eyes. These cells are responsible for producing a pigment called melanin, which gives color to the skin, hair, and eyes. Melanocytes play a crucial role in protecting the skin from the harmful effects of ultraviolet (UV) radiation by producing melanin, which absorbs and scatters UV light. The amount and distribution of melanin in the skin determine a person's skin color and helps protect the skin from sunburn and DNA damage. Melanocytes also contribute to the formation of freckles, moles, and other pigmented spots on the skin.
