Glioma cell’s motility is also influenced by various chemoattractants, which include ligands of scatter factor/hepatocyte growth factor (SF/HGF) (Lamszus et al., 1998), the EGF family (Lund-Johansen et al., 1990), the TGF-β family (Platten et al., 2001), SDF-1 (Zhou et al., 2002), and certain lipids (Young and Brocklyn, 2007). The gene discussed is HGF; the disease is glioma.
