希望长寿是人类共同的美好愿望。长期以来,人们都在努力探索长寿的秘方。科学家们经过研究发现,基因与长寿之间有着密不可分的关系:基因技术的发展和应用将有助人类长寿。据日本工业技术院和广岛大学的科学家日前发表的一项研究成果说,他们使用转基因技术增加了人体细胞的增殖能力,延长了细胞的寿命。报道说,科学家使用转基因技术,把具有维持细胞分裂功能的基因和促进细胞增殖的基因植入从人的脐带血管分离出来的血管内皮细胞中去,结果使血管内皮细胞的分裂次数从65次增加到200次以上,从而大大延长了细胞的寿命。参加这项研究活动的科学家三井洋司说:“这一技术适用于人体的各种细胞,并可望用以制造人的皮肤和骨骼等人造器官及进行细胞移
Hope that longevity is the common aspiration of mankind. For a long time, people are trying hard to explore the secret of longevity. Researchers have found that there is a close relationship between genes and longevity: the development and application of genetic technology will help people longevity. According to a study published by Japan’s Institute of Industrial Technology and Hiroshima University scientists recently, they used genetically modified technology to increase the proliferation of human cells and prolong cell life. Reported that scientists using transgenic technology, the gene has to maintain cell division and promote cell proliferation of genes implanted in human umbilical cord blood vessels isolated from the endothelial cells, resulting in the number of vascular endothelial cell division increased from 65 To 200 times or more, thus greatly extending the life of cells. Participate in the research activities scientist Mitsui Yang Division said: ”This technology applies to a variety of human cells, and is expected to be used to make human skin and bone and other artificial organs and cell migration
