A melanosome is an organelle found in animal cells and is the site for synthesis, storage and transport of melanin, the most common light-absorbing pigment

2012-04-01 · Melanosomes are packed in globules enclosed by the melanocyte plasma membrane, released into the extracellular space from various areas of the melanocyte dendrites, phagocytosed by keratinocytes, and are then dispersed around the perinuclear area. 2013-07-15 · Once mature and in place, melanocytes produce melanin, the pigment responsible for skin colour, which is exported to the surrounding keratinocytes (each melanocyte is connected to roughly 40 keratinocytes) in grain-like structures known as melanosomes. Melanosomes are organelles that produce and store melanin, a widespread biological pigment with a unique suite of properties including high refractive index, semiconducting capabilities, material stiffness, and high fossilization potential. They are involved in numerous critical biological functions … Melanosomes are morphologically and functionally unique organelles within which melanin pigments are synthesized and stored. Melanosomes share some characteristics with lysosomes, but can be distinguished from them in many ways. The biogenesis and intracellular movement of melanosomes and related or … Melanosomes are always internal, embedded in a morphologically distinct keratinous matrix.

melanocyte, albinism 2020-02-07 · Keratinocytes uptake melanosomes from melanocytes and retain them in the perinuclear region, where they form melanin caps. Although these processes are crucial to protecting nuclear DNA against ultraviolet injury, the molecular basis of melanosome uptake and decomposition in keratinocytes is poorly understood.
