Morphology of porcine aortic endothelial (PAE) cells expressing c‐Met mutants in three‐dimensional culture. PAE cells were cultured for 8 days in the absence (–) or presence (+) of hepatocyte growth factor (HGF) (50 ng/mL). The morphology of the cells was analyzed by light microscopy. Similar results were obtained in two clones of the wild‐type and mutant c‐Met. The results for one of them are shown. Scale bar = 10 µm.
