儿童侏儒症治疗有望

来源:华人健康网 | 发布时间:2010-08-22 11:13:53 | www.chinesejk.com
近日,3头帶有人类基因的克隆牛在阿根廷潘帕斯草原诞生。阿根廷科学家进行的这项生物工程试验为生物制药帶來前景。9月中下旬,在布宜诺斯艾利斯省一座庄园里,陆续诞生了3头小牛,它们是早些时候诞生的阿根廷第一头克隆牛的翻版,不过这3头小母牛是转基因克隆牛,它们的细胞中含有人类生长激素基因。从它俩的乳液中可以提取大量药用蛋白蛋,用以治疗儿童侏儒症。人工合成人类蛋白质在20多年前就已经开始,但是采用的是細菌和细胞培养法,产量很低。据科学家预测,6年之后世界生物技朮制品的需求將大大超过生产能力。
