正常的人类皮肤黑色素细胞(NHEM) 分离自青少年包皮的表面皮肤，或者各个部位的皮肤*，包括面部、乳房、腹部和大腿。这些细胞定位于皮肤的基底细胞层，但其分支位于基底细胞层以上的角质化细胞之间。
表皮中大约 5-10%的细胞为黑色素细胞。黑色素细胞的主要功能是产生黑色素，后者是一种蛋白质，负责使皮肤、眼睛和头发色素沉着黑色素可以保护皮肤中的细胞，以及更深层次的细胞免于受到紫外线的辐射伤害。黑色素产生并储存于黑色素体中，黑色素体在靠近黑色素细胞的细胞膜的地方，但也可以转移到邻近的角质化细胞中。
PromoCell黑色素细胞使用无血清的含有PMA（佛波醇十四醋酸酯）的黑色素细胞生长培养基或无血清、无PMA的黑色素细胞生长培养基2进行分离。
由于PMA是一种诱导肿瘤产生的促细胞分裂剂，它可能会干扰实验进程。因此，我们推荐使用在不含血清也无PMA的M2型黑色素细胞生长培养基2中分离的细胞，同时使用该培养基进行细胞培养。
The cells have been tested: Mel-5 positive

Epidermal melanocytes represent 5-10% of the cells in the epidermis. Located in the stratum basale with extensions to the suprabasal layers, they are specialized in the production of melanin. This protein is responsible for the pigmentation of the skin, hair and eyes and exerts a protective effect on adjacent cells by shielding them from the harmful effects of UV radiation.
PromoCell offers a range of Normal Human Epidermal Melanocytes (NHEM) produced at PromoCell’s cell culture facility from donors with lightly, moderately and darkly pigmented skin (detailed pigmentation-related donor-information available on request).
The cells are isolated from juvenile foreskin or adult skin from different locations, e.g. face, breast, abdomen and thighs, using either the serum free, PMA (Phorbol Myristate Acetate) containing Melanocyte Growth Medium or the unique serum-free and PMA-free Melanocyte Growth Medium M2. Since PMA is a tumor-promoting mitogen, which can interfere with experimental approaches, we recommend using Mel-anocytes isolated in Melanocyte Growth
Medium M2 and also using this medium for cultivation.
Shortly after isolation, all PromoCell Normal Human Epidermal Melanocytes are cryopreserved at passage 2 (P2) using PromoCell’s proprietary, serum-free freezing medium, Cryo-SFM. Each cryo vial contains more than 500,000 viable cells after thawing.
Proliferating cell cultures are made from 500,000 cryopreserved cells that have been thawed and cultured for three days at PromoCell.
