Description

Caki-1 is a human clear cell renal cell carcinoma (ccRCC) line that displays epithelial morphology and grows in adherent culture. When grown on transwell filters, these cells form a polarized monolayer with microvilli on the apical surface and display characteristic features of the proximal tubule epithelium. In addition, the Caki-1 cells are also a useful model to study renal cancer. They are more sensitive to 5-fluorouracil and sorafenib (multi-kinase inhibitor of VEGFRs 1-3, PDGFR-b and Raf-1) than the Caki-2 cells. The Caki-1 cells express wildtype von Hippel-Lindau (VHL) tumor-suppressor protein and are known to form tumors in immunocompromised mice.

This cell line was established in 1971 from a metastatic site (skin) in a 49-year-old Caucasian male with clear cell carcinoma of the kidney.
