美国首次对人类胚胎进行基因编辑，或能消除家族遗传病
<p>美国在2017年初对基因编辑技术谨慎放开后，国内科学家就开始在该领域内迈出大步伐。据美国有线电视资讯网（<span word="CNN">CNN</span>）报道，俄勒冈卫生科学大学的科学家舒赫拉特•米塔利波夫（<span word="Shoukhrat">Shoukhrat</span> <span word="Mitalipov">Mitalipov</span>）团队使用基因编辑技术进行了美国首例转基因人类胚胎实验。由于牵扯道德伦理问题，人类胚胎研究屡屡处于争议之中。迄今，只有中美两国实施过人类胚胎基因编辑。</p><p><span word="The">The</span> <span word="MIT">MIT</span> <span word="Technology">Technology</span> <span word="Review">Review</span> <span word="published">published</span> <span word="on">on</span> <span word="Wednesday">Wednesday</span> <span word="a">a</span> <span word="news">news</span> <span word="report">report</span> <span word="about">about</span> <span word="the">the</span> <span word="first">first</span>-<span word="known">known</span> <span word="experiment">experiment</span> <span word="to">to</span> <span word="create">create</span> <span word="genetically">genetically</span> <span word="modified">modified</span> <span word="human">human</span> <span word="embryos">embryos</span> <span word="in">in</span> <span word="the">the</span> <span word="United">United</span> <span word="States">States</span> <span word="using">using</span> <span word="a">a</span> <span word="gene">gene</span>-<span word="editing">editing</span> <span word="tool">tool</span> <span word="called">called</span> <span word="CRISPR">CRISPR</span>.</p><p>《麻省理工技术评论》杂志16日报道，美国使用基因编辑工具<span word="CRISPR">CRISPR</span>进行了本国首例转基因人类胚胎实验。</p><p><span word="Shoukhrat">Shoukhrat</span> <span word="Mitalipov">Mitalipov</span>, <span word="director">director</span> <span word="of">of</span> <span word="the">the</span> <span word="Oregon">Oregon</span> <span word="Health">Health</span> & <span word="Science">Science</span> <span word="University">University</span>'<span word="s">s</span> <span word="Center">Center</span> <span word="for">for</span> <span word="Embryonic">Embryonic</span> <span word="Cell">Cell</span> <span word="and">and</span> <span word="Gene">Gene</span> <span word="Therapy">Therapy</span>, <span word="reportedly">reportedly</span> <span word="led">led</span> <span word="the">the</span> <span word="new">new</span> <span word="research">research</span>. <span word="Mitalipov">Mitalipov</span> <span word="and">and</span> <span word="the">the</span> <span word="university">university</span> <span word="would">would</span> <span word="not">not</span> <span word="confirm">confirm</span> <span word="details">details</span> <span word="of">of</span> <span word="the">the</span> <span word="research">research</span> <span word="to">to</span> <span word="CNN">CNN</span>.</p><p>据报道，俄勒冈卫生科学大学胚胎干细胞与基因治疗中心主任舒赫拉特•米塔利波夫是这项新研究的领头人。舒赫拉特及校方不愿向<span word="CNN">CNN</span>透露研究的细节。</p><p>"<span word="Results">Results</span> <span word="of">of</span> <span word="the">the</span> <span word="peer">peer</span>-<span word="reviewed">reviewed</span> <span word="study">study</span> <span word="are">are</span> <span word="expected">expected</span> <span word="to">to</span> <span word="be">be</span> <span word="published">published</span> <span word="soon">soon</span> <span word="in">in</span> <span word="a">a</span> <span word="scientific">scientific</span> <span word="journal">journal</span>. <span word="No">No</span> <span word="further">further</span> <span word="information">information</span> <span word="will">will</span> <span word="be">be</span> <span word="provided">provided</span> <span word="before">before</span> <span word="then">then</span>," <span word="according">according</span> <span word="to">to</span> <span word="an">an</span> <span word="emailed">emailed</span> <span word="statement">statement</span> <span word="from">from</span> <span word="the">the</span> <span word="university">university</span>'<span word="s">s</span> <span word="press">press</span> <span word="office">office</span>. <span word="Another">Another</span> <span word="researcher">researcher</span> <span word="cited">cited</span> <span word="in">in</span> <span word="the">the</span> <span word="MIT">MIT</span> <span word="report">report</span>, <span word="the">the</span> <span word="Salk">Salk</span> <span word="Institute">Institute</span>'<span word="s">s</span> <span word="Jun">Jun</span> <span word="Wu">Wu</span>, <span word="did">did</span> <span word="not">not</span> <span word="reply">reply</span> <span word="to">to</span> <span word="CNN">CNN</span>'<span word="s">s</span> <span word="request">request</span> <span word="for">for</span> <span word="comment">comment</span>.</p>
