黑素细胞是一种腺细胞,能在细胞内合成黑素,将其分泌并输送到附近的角朊细胞中去.因角朊细胞也参与黑素的代谢,Fitzpatrick将它和黑素细胞合称为表皮黑素单位(epidermal melanin unit).每个表皮黑素单位约由一个黑素细胞与36个左右的角朊细胞组成.清寺真又增添了黑素向真皮移行及随之消失的过程,综合称为皮肤黑素单位(skin melanin unit).皮肤黑素单位主要包括四个方面:①黑 Melanocytes, a type of glandular cell that synthesizes melanin in the cell, secrete it and deliver it to nearby keratinocytes. Fitzpatrick names it together with melanocytes, because keratinocytes are also involved in the metabolism of melanin Epidermal melanin unit (epidermal melanin unit) .Every epidermal melanin unit about a melanocyte and about 36 keratinocytes.Jing Temple also added melanin to the dermis and the disappearance of the process, Generally referred to as the skin melanin unit (skin melanin unit). Melanoma unit mainly includes four aspects: ① black
