Figure 6From: Galectin-1, a gene preferentially expressed at the tumor margin, promotes glioblastoma cell invasionOver-expression of galectin-1 in orthotopic xenografts alters the tumor phenotype. Although the typical U87MG tumor xenograft is non-invasive, galectin-1 transfected U87MG clones formed tumors showing some invasion at the tumor-brain interface. Selected sections were stained using a human-specific anti-vimentin antibody.Back to article page
