Abstract:
Cartilage antuumor component (CATC) was isolated from a 1 mol/L guanidine hydrochloride extract of bovine cartilage by acetone fractioned precipitation and superfiltration. Using human skin fibroblasts as a normal control, it was demonstrated that CATC inhibited the DNA synthesis of Hela, QGY7703 tumor cell lines and bovine artery endothelial cells, but accelerated the normal cells, when the concentration was below 1250 ?g/ml. At the concentration of 5 000 ?g/ml, CATC inhibited the two cell lines. With human tumor stem cell assay, CATC inhibited the stem cell growth of Hela and QGY7703 cell lines. These suggest that CATC has the effects of inhibiting angiogenesis and tumor cells.
