The mechanism of inhibition of metastasis by cartilage polysaccharide in breast-cancer cells.

As large amounts of porcine cartilage are discarded as waste in daily life, it is necessary to find new uses for them. We extracted polysaccharide from cartilage and performed in vitro and in vivo experiments in cancer cells. A mouse breast-cancer pulmonary metastasis model was set up, and we tried to determine the mechanism of the inhibition of metastasis by cartilage PS (polysaccharide).
