U.S. President Donald Trump9s administration is taking steps to limit the use of human fetal tissue from elective abortions in biomedical research. Last week, administration officials told researchers at one California university that their contract work involving fetal tissue would not receive the usual 1-year extension. And Science has learned that this past September, officials quietly ordered scientists employed by the U.S. National Institutes of Health (NIH) to stop acquiring new human fetal tissue for experiments. Both moves come as the Trump administration has launched a review of all federally funded research with fetal tissue, which is used to study several diseases. The actions have prompted fears that NIH-funded university scientists who work with fetal tissue could face a broader clampdown.

特朗普官员采取行动限制人类胎儿组织研究

美国总统唐纳德特朗普的政府正在采取措施限制在生物医学研究中使用来自选择性流产的人类胎儿组织。上周，政府官员告诉加州一所大学的研究人员，他们涉及胎儿组织的合同工作不会获得通常的 1 年延期。《科学》获悉，今年 9 月，官员们悄悄下令美国国立卫生研究院 (NIH) 雇用的科学家停止获取新的人类胎儿组织进行实验。这两项举措出台之际，特朗普政府已启动对所有联邦资助的胎儿组织研究进行审查，胎儿组织用于研究多种疾病。这些行动引发了人们的担忧，即 NIH 资助的研究胎儿组织的大学科学家可能会面临更广泛的打击。
