Cell:日本学者让老鼠变“透明” 有助理解器官3D结构

日本研究人员通过消除组织的颜色使老鼠透明可见,从而助于研究癌细胞如何扩散,寻求治疗癌症的灵丹妙药。

通过消除组织颜色的过程中逐渐杀死老鼠,可以不用通过解剖的方法检查单个器官或是整体。这也为研究癌细胞的扩散问题提供了一个更为清楚的视角。东京大学(University of Tokyo)和日本科学振兴机构(Japan Science and Technology Agency)通过将盐溶液注入到老鼠的心脏里,以此来挤压循环系统中的血液,将老鼠体内的血红素挤压出来达到透明的目的,然后将其浸泡在试剂中两周后可用于研究。

美国《细胞》(Cell)杂志中有关作者认为,该项技术能够让科学家对器官的3D结构和不同组织中基因的表达有一个新的了解。虽然我们可以用显微镜观察物体的细微处,但是它毕竟不利于用于整体观察。

该研究的负责人弘纪上田(Hiroki Ueda)表示,此方法可以从细胞阶段研究胚胎和癌症等自身免疫病的发展,借此找到治疗这些疾病的新策略。
