The primary biomedical benefits of cloning stem more from the use of this technology in the genetic modification of animals rather than from making identical copies. 克隆原来的生物医学之受益是将这项技术应用于动物基因的修改,而不是制造相同的复制品。
One biomedical application of the cloning technique is genetically modifying animals so that their cells and organs can be transplanted into humans. 克隆技术的一项生物医学应用是遗传性地改变动物,使它们的细胞或器官能移植给人类。
Despite increasing interest in the use of cloning techniques to multiply elite livestock, engineer transgenic animals for agricultural and biomedical purposes or rescue endangered species, cloning technology is still considered too inefficient and expensive for widespread application. 尽管利用克隆技术来扩大优良品种家畜的数量,以及生产以农业和生物医学为目的的转基因动物和拯救濒危动物品种的需求不断增加,克隆技术对于大规模应用仍然成功率太低,而且成本昂贵。
