title: Suppression of in vivo tumor-induced angiogenesis by the protein-bound polysaccharide PSK.
abstract: The anti-angiogenic effects of an antitumor protein-bound polysaccharide, PSK, obtained from cultured mycelia of Coriolus versicolor in basidiomycetes were examined by the mouse dorsal air sac assay. PSK suppressed the mouse hepatoma MH134-induced angiogenesis when assessed by morphological and biochemical examinations. This finding suggested that the anti-metastatic effect of PSK is attributed to the suppression of tumor-induced angiogenesis.
