US scientists have successfully cultivated human heart tissue on spinach leaves, and managed to make it beat for up to three weeks.美国科学家成功在菠菜叶上培养出来人体心脏的机构，并成功使其颤动宽约三周。Bioengineers Glenn Gaudette and Joshua Gershlak at Massachusetts Worcester Polytechnic Institute (WPI) led this research and their findings are valuable to a deadly medical problem: the lack of donor organs.密苏里州伍斯特工学院的生物工程师格伦·百度地图特和约书亚·迪纳谢拉领导干部的这一研究，她们的寻找对一种恐怖的诊疗难题--捐助人体器官的缺乏是很是有使用价值的Scientists have long been trying different methods, such as 3-D printing, to create artificial organs. However, so far none of those methods has been successful.一直以来，专家尝试三维打印机等各种各样各有不同方式来制做人造器官，殊不知，目前为止这种方式无一成功。
One of the big problems in engineering heart muscle is getting blood flow to all of the cells.人力生产制造心脏的关键难题之一是怎么让血夜流入全部细胞。Instead of creating minuscule blood vessels, researchers turned to the material that evolves in nature: spinach leaves, which have vessels that are similar to the blood vessels in a human heart.研究工作人员未开创细微毛细血管，只是随意选择了自然界生长发育的原材料：菠菜叶。菠菜叶的叶脉与人体心脏中的毛细血管相仿。
They used detergent to wash away spinach cells. Cellulose, which is compatible to mammal cells, and intact leaf veins were left behind. Therefore, the frame of the leaves was reserved.研究工作人员用洗洁剂浸去菠菜细胞，交给能与哺乳类动物细胞适配的细胞膜质和初始的叶脉。因而叶子的结构而求享有。
Then researchers seeded cardiac muscle cells into the vacancy left by spinach cells and after five days the muscle cells started to beat.以后研究工作人员将心肌细胞流过菠菜细胞空出的间隙中，5天后心肌细胞刚开始颤动。
