Figure 1From: Progression of renal cell carcinoma is inhibited by genistein and radiation in an orthotopic model Generation of KCI-18/IK cell lines. KCI-18 cells were injected in the kidney of nude mice. Tumor cells were isolated from kidney tumors, expanded in culture and reinjected into mice kidneys. Three serial in vivo passages in the kidney resulted in new tumorigenic cell lines KCI-18/IK.Back to article page
