MET and colorectal carcinoma: In addition, stimulation of HCT116 and LoVo cells with recombinant human HGF (rh-HGF) (25 ng/ml) resulted in significant increases in migration (p < 0.001) and invasion (p < 0.001) rates (Figure 4A), confirming the key role of the HGF/c-MET axis in mediating CRC cell migration and invasion in the context of the TME.
