如果一个人能像研究人的生命那样研究细胞的生命，那么发现生物或生物体的基本规律就不难了。在宏观尺度上，人们知道一个人是如何出生、成长和繁殖的，他能活多久，他如何旅行和在哪里旅行，他的行为和与他人的互动。所有这些都是可以观察甚至测量的。另一方面，在细胞的微观领域，人们必须在黑暗中摸索，只有付出巨大的努力才能获得这些信息。然而，研究细胞的学生所使用的工具正变得越来越锋利，在过去的二十年里，用于探索细胞生命的设备已经进入了一个新的分辨率范围。本文介绍一种特别有前途的技术：细胞放射自显影。作为放射性示踪剂使用的改进，它已经产生了许多关于细胞行为的新信息。
If one could study the lives of cells as one can study the life of a man, it would not be difficult to discover the fundamental laws of biological or ganisms. On the macroscopic scale one knows how a human being is born, grows and reproduces, how long he lives, how and where he travels, behaves and in teracts with others. All of this is acces sihle to observation and even to measurement. In the microscopic realm of the cell, on the other hand, one must largely grope in the dark, and such information can be won only with great labor. The tools employed by the student of cells, however, are becoming sharper, and in the past two decades devices for exploring the lives of cells have en tered a new range of resolving power. This article is an account of a particularly promising techniLlue: the radioautog raphy of cells. A refinement of the use of radioactive tracers, it has already yielded much new information about cell behavior.
