“日本XXXXXX19—30”日本研究人日本XXXXXX19—30员成功将叶绿体植入动物细胞

  近日日本XXXXXX19—30,日本东京大学等机构的日本XXXXXX19—30研究人员从藻类中提取具有光合作用活性的叶绿体,并成功移植到仓鼠的培养细胞内。移植的叶绿体在仓鼠培养细胞中光合作用活性保持了至少两天。

  东京大学日前发布新闻公报说,他们和日本理化学研究所等机构合作进行了这项研究。叶绿体是植物细胞中进行光合作用的细胞器。由于动物细胞将叶绿体识别为异物并加以消化,因此很难将叶绿体移植到动物体内。

  研究人员本次开发的叶绿体移植法可以不使用以往的导入器材和物理方法,一次最多将45个叶绿体导入仓鼠的培养细胞内,并且不影响细胞正常的增殖。移植的叶绿体在仓鼠培养细胞中保持光合作用活性至少两天。另外,研究人员用荧光激光显微镜分析和超分辨率显微镜拍摄细胞断层像,结果显示,被导入的叶绿体存在于细胞质中,其中一部分围绕着细胞核。

  相关研究成果已发表在《日本学士院纪要》上。(制作 徐妙巧)
