The uses of stem cells 干细胞的应用 Potent medicine 特效医学 Stem cells may transform the development of newdrugs 干细胞可能改写新药发展 PLURIPOTENT is a long word that means able to do many things. 多能的意思是能做很多事。 It is the technical term applied to stem cells that can generate many different sorts ofbodily tissue, rather than just one sort, which is all that lesser stem cells can manage. 这一技术术语适用于可分化成多种不同身体组织的干细胞，而不是像次级分化干细胞一样只可以分化成一种身体组织。 But many researchers hope these cells will be pluripotent in other ways, too. 但是研究者希望干细胞在其他方面也具备多能性。 Not only might they be used to make replacementtissues and organs for transplantation into those whose existing body parts no longer workproperly, they might also be used to produce pure cultures of cells for the early testing ofdrugs. 干细胞不仅可用于获得某些身体部分运作不良者移植用的替换组织或器官，还可以用于培养药物早期试验用的纯系细胞。 The culturing and use of human pluripotent stem cells is controversial because the naturalsource of such cells is embryos, which are destroyed by the process of extraction. |
