　　Some scientists want to apply the methods used in cloning animals to produce skin, organs, and other body parts for humans. One of these methods involves taking adult cells from the brain or blood and growing them into new tissues. Another, more complex, technique takes embryo cells and develops them into a wide variety of cell types and tissues.

　　一些科學(xué)家想用克隆動(dòng)物的方法，來(lái)為人類(lèi)制造人類(lèi)使用的皮膚、器官與其它的身體構(gòu)造。其方法之一是從腦內(nèi)或血液中提取成熟細(xì)胞，把它們培養(yǎng)成新組織。另外一種較為復(fù)雜的技術(shù)，則是把胚胎細(xì)胞培養(yǎng)成各式各樣的細(xì)胞種類(lèi)及組織。
