内皮抑素可抑制血管形成和肿瘤生长近年的一系列研究表明，血管形成是实体瘤生长与转移的基础。为了促进血管形成，肿瘤细胞可增加一系列血管形成因子的产生。但许多恶性肿瘤也可产生血管形成抑制因子，如血管抑素（ａｎｇｉｏｓｔａｔｉｎ）、血栓海绵素等。血管形成因子... Endostatin inhibits angiogenesis and tumor growth. A series of recent studies have shown that angiogenesis is the basis of solid tumor growth and metastasis. To promote blood vessel formation, tumor cells increase the production of a series of angiogenic factors. However, many malignant tumors can also produce angiogenesis inhibitors such as angiostatin and thrombocytopin. Angiogenesis factor...
