  1. Are MDA-MB435 cells mammary carcinoma cells or melanoma cells?

    Holliday and Speirs discuss in their illuminating review on breast cancer cell lines as models for breast cancer research the cell line MDA-MB435, which has been considered as a breast cancer cell line until reports on their potential origin from a human melanoma (see ref. in Holliday and Speirs). More recent evidence shows that i) MDA-MB435 are indeed identical to M14 melanoma cells, ii) M14 were derived from a male melanoma patient but carry two X-chromosomes whereas MDA-MB435 were derived from a female patient (Chambers, Cancer Res. 2009, 5292; Hohestelle and Schutte, Cancer Res. 2009, 7893) and iii) 18% of human breast cancers express melan-A and other melanoma markers (Bachmeier et al. Int J Oncol. 2008, 1011). MDA-MB435 cells are therefore most likely breast cancer cells.
