美国哈佛大学的研究人员在结肠癌细胞中发现了一种能刺激血管生长的蛋白质,称它为血管生长素(angiogenin),他们已把这种蛋白质提纯,并测定了其氨基酸排列顺序。研究人员认为,这种血管生长素对心肌梗塞可能会提供一种比目前所用的疗法损伤较少而益处更大的治疗方法,而且对骨折的愈合可能 Researchers at Harvard University in the United States have discovered a protein in the colon cancer cells that stimulates blood vessel growth. Call it angiogenin. They have purified this protein and determined the amino acid sequence. The researchers believe that this type of angiogenin may provide a treatment with less damage to the myocardial infarction than the current treatment, and the benefit is greater, and the healing of the fracture may be
