While floating inside the transparent plastic vessel - in some cases for four weeks - the lambs appeared to develop normally, transforming from bald, pink fetuses into fleecy, white newborns.在这类透明色塑料制品中悬浮的全过程中,这种小羊也许长期发育了(一些状况下只需4周),从光溜溜、粉嫩嫩的胎宝宝变成了毛绒绒的乳白色新生儿羔羊。Doctors said that the pioneering approach could radically improve outcomes for human babies born so early that they cannot breathe, feed or fight infection without medical help.医生们称作,这类开拓性的方式能够彻底提升人们早产儿没经诊疗輔助就没法大便、喂养、抵御病毒性感染的情况。If we can support growth and organ maturation for only a few weeks, we can dramatically improve outcomes for extremely premature babies, Alan Flake, a foetal surgeon at the Childrens Hospital of Philadelphia (CHOP) and lead author said.费城儿科医院的胎宝宝外科医师、该科学研究的顶尖创作者莱纳·弗莱克答复:“如果我们能在胎宝宝发育和人体器官成熟层面获得好多个礼拜的帮助,那麼大家就能非常大的提升早产儿的状况。
