Sometimes the donor is a living volunteer. Usually, though, he or she is the victim of an accident, stroke, heart attack or similar sudden event that has terminated the life of an otherwise healthy individual. But a lack of suitable donors, particularly as cars get safer and first-aid becomes more effective, means the supply of such organs is limited. Many people therefore die waiting for a transplant. That has led researchers to study the question of how to build organs from scratch.每年约有 12 万个器官(主要是肾脏)从一个人身上移植到另一个人身上。有时器官由仍健在的志愿者捐赠，但通常状况下捐赠者都是因事故、中风、心脏病或类似突然事件而猝然离世的健康人。但因缺少合适的捐赠者，特别是在汽车变得更安全、急救变得更有效的状况下，上述途径供应的器官已十分有限。因此，很多人在等待移植的过程中就去世了。这促使讨论人员着手讨论从零打造器官的问题。One promising approach is to print them. Lots of things are made these days by three-dimensional printing, and there seems no reason why body parts should not be among them. As yet, such "bioprinting' remains largely experimental. But bioprinted tissue is already being sold for drug testing, and the first transplantable tissues are expected to be ready for use in a few years time.一个有望胜利的方法是 3D 打印。如今许多东西都是通...
