Abstract :
Whole-culture or batch synchronization cannot, in theory, produce a synchronized culture because it violates a fundamental law that proposes that no batch treatment can alter the cell-age order of a culture. In analogy with the history of perpetual-motion machines, it is suggested that the study of these whole-culture ‘synchronization’ methods might lead to an understanding of general biological principles even though these methods cannot be used to study the normal cell cycle.
