Somewhat more formally, for a set Ï of properties and relations, a Ï-representation of some structure X is a structure Y that is the image of X under a s homomorphism that preserves Ï. The label representation is sometimes also applied to the homomorphism itself.
Melanoma. This cancer begins in the melanocytes, the cells that provide the skinâs color. Melanoma is one of the deadliest forms of skin cancer because it can spread rapidly inside the body. Approximately one American dies from melanoma every hour.
Melanin granules synthesized in the melanocytes are then transferred from the cytoplasm of the melanocytes to the basal cytoplasm of the keratinocytes. In the human epidermis, melanocytes work in close harmony with their neighbouring cells such as keratinocytes via their dendrites.
