PATHOLOGY

Detailed explanation-1: -Also, when melanin fails to protect the skin against sun damage, the most common type of skin cancer that can develop is melanoma. Melanoma is, in fact, a type of cancer that develops in melanocytes, which are the cells that produce melanin [3].

Detailed explanation-2: -Melanocyte stem cells differ greatly from melanoma stem cells; the former provide pigmented cells during normal tissue homeostasis and repair, while the latter play an active role in a lethal form of cancer. These two cell types share several features and can be studied by similar methods.
