Melanocytes phagocytize melanin. First, melanocytes which are present in the lowest or basal layer of the epidermis, produce the pigment melanin. The melanin forms granules called melanosomes. After the keratinocytes take up the pigment, it clusters around the keratinocyte nucleus on the superficial side. This protects the DNA in the keratinocyte nucleus from damage due to UV radiation.

What is the layer of epidermis that has pigment-producing melanocytes?
The layer of the epidermis that has pigment-producing melanocytes is the stratum basale (basal layer). Melanocytes produce melanin, the pigment responsible for skin color, and transfer it to surrounding keratinocytes.
Pertaining to skin cells?
Skin is made up of various types of cells, including keratinocytes, melanocytes, and Langerhans cells. Keratinocytes are the most abundant and produce the protein keratin that provides strength and protection. Melanocytes produce melanin, the pigment that gives skin its color and helps protect against UV damage. Langerhans cells are part of the immune system and help protect against pathogens.
What is the difference of melanocytes and keratinocytes?
Answer taken from the article:Costin & Hearing (2007). Human skin pigmentation: Melanocytes modulate skin color in response to stress. The Faseb Journal, 21(4), 976-994."Melanin biosynthesis is a complex pathway that appears in highly specialized cells, called melanocytes, within membrane-bound organelles referred to as melanosomes. Melanosomes are transferred via dendrites to surrounding keratinocytes, where they play a critical role in photoprotection. The anatomical relationship between keratinocytes and melanocytes is known as 'the epidermal melanin unit' and it has been estimated that each melanocyte is in contact with ∼40 keratinocytes in the basal and suprabasal layers."Translated: Melanocytes produce melanin in nice little packages called, melanosomes. These melanosomes are then transferred to neighboring keratinocytes (i.e., the hair follicle) through dendrites. This is how the hair follicle gets its color, even though the actual hair follicle doesn't produce melanin itself.
What epidermal cell produces keratin?
Keratinocytes
What is the function of the melanocytes?
- A cell of the statum basale of the epidermis that synthesizes melanin and transfers it to the keratinocytes.- Any of the dendritic clear cells of the epidermis that synthesize tyrosinase and, within their melanosomes, the pigment melanin; the melanosomes are then transferred from melanocytes to keratinocytes.
Melanocytes and keratinocytes work together in protecting the skin from the UV damage when keratinocytes?
Accumulate the melanin granules on their superficial portion, forming a pigment that protects DNA from UV radiation
What cells produce keratin and melanin?
Keratinocytes or squamous cells produce keratin and Melanocytes produce melanin, pigment.
What are keratinocytes?
Keratinocytes are the epidermal cells of the skin.
What is the layer of epidermis that has pigment-producing melanocytes?
The layer of the epidermis that has pigment-producing melanocytes is the stratum basale (basal layer). Melanocytes produce melanin, the pigment responsible for skin color, and transfer it to surrounding keratinocytes.
In what layer of skin are keratinocytes predominant?
Keratinocytes are predominant in the epidermal layer of the skin.
Why are Keratinocytes dead?
because those are the keratinocytes that are about the be shed... not really any other reason
The general external surface has been phagocytized of the amoeba in the?
plasma membrane
What makes keratin?
keratinocytes
Is atypical keratinocytes cancer?
No
What contains material that has been phagocytized and is in the process of being digested?
food vacuole
