But discrepancies issue degradation of melanosomes and their top quality. Hair melanocytes, in distinction to epidermal types, contain mainly even larger experienced Phase IV melanosomes (melanogenesis and stages of melanosomes are explained additional With this work) and much more expanded Golgi equipment and tough endoplasmatic reticulum (RER). These pigment cells are larger sized plus more dendritic than epidermal ones [31, 33]. In addition, in epidermis Pretty much total transported melanin is degraded within the differentiating keratinocytes, but in hair cortical keratinocytes pigment granules are digested only a bit [33].
