Primary Normal Human Epidermal Melanocytes (NHEM) are isolated from the epidermis of juvenile foreskin or adult skin from different locations including the face, the breasts, the abdomen, and the thighs. They are located in the stratum basale, but branch out between the keratinocytes in suprabasal layers. About 5-10 % of the cells in the epidermis are melanocytes. The main purpose of melanocytes is the production of melanin, the protein responsible for the pigmentation of the skin, eyes, and hair. Melanin protects the cells in the skin and in deeper layers from the hazardous effects of UV radiation.
- Available from juvenile foreskin or adult skin from different locations
- Available from light moderate and dark skin tones
- Donor hair and eye color available on request
- Mel-5 positive
- Cultured in PMA containing or PMA-free Medium
It is produced and stored in melanosomes, which are located close to the melanocyte membrane, but it can also be transferred to neighboring keratinocytes
This product can be used in the following applications. Dermatological research, Melanoma research, Melanogenesis studies, Cosmetic and toxicological testing, Skin compound screening.
PromoCell melanocytes are isolated using either the serum-free, PMA (Phorbol Myristate Acetate)-containing Melanocyte Growth Medium or the serum-free and PMA-free Melanocyte Growth Medium M2. Since PMA is a tumor promoting mitogen, it can interfere with experimental approaches. Therefore, we recommend using cells isolated in Melanocyte Growth Medium M2 and also using this medium for cultivation. Normal Human Epidermal Keratinocytes (NHEK) and Normal Human Dermal Fibroblasts (NHDF) from the same donor are available on request.
Ordering information: Human Epidermal Melanocytes can be ordered as cryopreserved or proliferating cells and from juvenile and adult donors. Additional cell pellets stored in RNAlater® are available.
