Which of the layers of the epidermis produces new keratinocytes and melanin? stratum basale Recall that melanin is produced by cells called melanocytes, which are found scattered throughout the stratum basale of the epidermis. WebMelanocytes produce specific organelles, termed melanosomes, ... Where is melanosome found? Melanosomes are synthesised in the skin in melanocyte cells, as well as the eye in choroidal melanocytes and retinal pigment epithelial (RPE) cells.
