Hepatocyte growth factor (HGF) accelerates renal tubule cell regeneration and induces tubulogenic differentiation via the intracellular tyrosine kinase (TK) domain of its receptor, the proto-oncogene c-Met. We tested whether different signaling pathways may be involved by examining HGF binding and effects on cell proliferation, migration, scattering, and tubulogenic differentiation in the bipolar differentiating rabbit proximal tubule cell line PT-1 under serum-free conditions in the presence or absence of the protein TK inhibitors (PTKIs) herbimycin-A, genistein, methyl-2,5-dihydroxycinnamate, and geldanamycin. These PTKIs inhibit pp60(c-src), a nonreceptor TK involved in cell-growth control. HGF bound to a single high-affinity receptor class, increased microvilli numbers 1.5-fold, enhanced cell proliferation and migration 1.8-fold, and stimulated formation of tubule structures 2.2-fold. PTKI inhibited the mitogenic and motogenic effects of HGF with different potencies and comparable maximal effects but had no specific influence on HGF-induced tubulogenic cell differentiation. These data underline the importance of pp60(c-src) in mediating mitogenic and motogenic effects of HGF, whereas stimulation of tubulogenic cell differentiation may be transduced by a pp60(c-src)-independent pathway.
