Human iPSC-derived Melanocytes


Human iPSC-derived Melanocytes

Melanocytes are cells that produce melanin and they reside mostly in the epidermis (top) layer of human skin, as well as in the hair follicles and iris. Melanocytes form a heterogeneous group of cells, and they are also found in multiple regions in the human body (such as the inner ear). Their lineage as a cell type arises from neural crest cells. In the human skin, the ratio of melanocytes to keratinocytes is 1:10 (which is independent of ethnicity) in the epidermal basal layer.

Tempo-iMel™: human melanocytes are derived from human induced pluripotent stem cell (iPSC) lines under a fully defined proprietary reprogramming and maturation conditions. Tempo’s iMel™ cells are branched elaborate structures when plated as a monolayer in culture and express biomarkers such as Vimentin, S100beta, and cytokeratins. iMel™ can be used under maturation conditions, co-culture conditions (with fibroblasts, keratinocytes or additional epidermal subtypes), and short-term functional characterization studies.
