But for melanin to do its job, melanosomes need to be transported to the keratinocytes via the melanocytes' long projections. Inside the keratinocytes, some melanosomes form a cap around the cell nucleus.

Marks3 1Institut Curie, Centre de Recherche, Paris, F-75248 France 2CNRS, UMR144, Paris, F melanosomes are formed, i.e., (a) ellipsoidal-lamellar melano­ somes ofBI6 type, which are also seen in normal skin and black hair, and (b) spherical-granular melanosomes of Harding Passey (HP) type seen also in normal yellow and red hair. In both types of melanosomes, the earliest form (stage I) is identical under electron microscopy. Such clustered distributions of melanosomes within keratinocytes suggest that phagosomal structures are actively formed by keratinocytes during phagocytosis and that they do not represent remnants of melanocyte dendrites.

A melanosome is an organelle in which melanin is synthesized. The end product of its action is the melanin granule (now called stage IV melanosome) into which it is ultimately transformed. Melanosomes are produced by melanocytes; melanosomes in early stages of development are found only in … 2018-09-26 Melanosomes are formed through a series of well-defined stages.
