WM3060 Viable Cells

Cells are sterile, validated by short tandem repeat profiling, and are tested as negative for mycoplasma. It is recommended that cell lines are tested for mycoplasma contamination and short tandem repeat (STR) profiling every 10 passages or each time a frozen seed stock is made. See cell culture protocol for additional details. WM3060 is a metastatic human melanoma cell line established from a metastatic site (left axillary nodes) in a 55-year-old male with level III malignant melanoma. The subject displayed VGP, and RGP with a tumor thickness of 3.0 mm. This cell line was derived from the same patient as the cell lines WM2013, and WM1960. This cell line contains a Q61K mutation at position 61 in the N-RAS gene which causes increased signaling via the extracellular signal-regulated MAPK/ERK kinase pathways to enhance proliferation. This cell line is wild type for BRAF, PTEN, c-KIT, and CDK4. WM3060 cells produce xenograft tumors when injected into immunocompromised mice.
