哈佛医学院的外科教授Judah Folkman最近在伦敦的汽巴基金会上称,血小板中一种称为血小板因子4的蛋白能够阻止供给肿瘤营养的小毛细血管的突然生长。在月经周期、胚胎发育期和创伤愈合期,通常都有血管生长。但是上述毛细血管的定向生长,也就是大家所知道的血管生成,也在肿瘤的早期发生。携带氧和营养的血液由迅速生长的毛细血管带给正在增大的肿瘤。如果使血管生成停止,实际上肿瘤也将被窒息。毛细血管在以下几个阶段生长:从母体的 Judah Folkman, a professor of surgery at Harvard Medical School, recently told the Ciba Foundation in London that a protein called platelet factor 4 in platelets can stop the sudden growth of small capillaries that supply tumor nutrition. In the menstrual cycle, embryonic development and wound healing, there is usually blood vessel growth. However, the directional growth of the capillaries mentioned above, which is known as angiogenesis, also occurs in the early stage of the tumor. Blood carrying oxygen and nutrients is brought to the growing tumor by the rapidly growing capillaries. If angiogenesis is stopped, the tumor will actually be suffocated. Capillaries grow in the following stages: from maternal
