Two stable cell lines, designated as NIH-Met5 (mouse fibroblast) and T24-Met3 (human bladder cancer cell), were established to harbor the inducible c-Met gene, which was expressed only in the absence of tetracycline (Tet) (Figure 1A, lane 3 and 4; Figure 1B, lane 1). Here, MET is linked to urinary bladder carcinoma.
