干细胞的研究始于20世纪60年代,造血干细胞的发现使人们对干细胞有了初步的了解。近年来,随着生物、医学技术的迅猛发展,人们对干细胞有了更深刻的认识:于细胞是一类具有自我更新能力及多分化潜力的细胞,它具有非常重要的理论研究意义和临床应用价值。尤其当人类胚胎干细胞研究成果被《科学》杂志评为1999年世界十大科技进展之首后,各国政府纷纷重视并在不同程度上支持该领域
Stem cell research began in the 1960s, and the discovery of hematopoietic stem cells has led to an initial understanding of stem cells. In recent years, with the rapid development of biology and medical technology, people have a more profound understanding of stem cells. Cells are a kind of cells with self-renewal ability and multi-differentiation potential. They have very important theoretical significance and clinical application value. In particular, when the research results of human embryonic stem cells were ranked by Science as the world’s top-10 science and technology progress in 1999, governments of all countries attached great importance to it and supported it in varying degrees
