Facts about Melanocyte
- 05
A single melanocyte can supply melanin to approximately 36 surrounding keratinocytes, a unit sometimes called the epidermal melanin unit.
- 04
The primary function of a melanocyte is to produce melanin through a process called melanogenesis, which is triggered by ultraviolet radiation exposure.
- 03
Melanocytes originate embryonically from neural crest cells, which migrate to the skin, hair follicles, and eyes during development.
- 02
Each melanocyte forms an extended network of dendrites to supply melanin to dozens of surrounding keratinocytes.
- 01
Specialized pigment-producing cells called melanocytes are located in the basal layer of the epidermis and transfer melanin granules to surrounding keratinocytes.
