Somatic mutations and cellular aging: two-dimensional DNA typing of rat fibroblast clones.

Abstract excerpt

Aging may be explained, to some extent, as a stochastic process of macromolecular damage. The rate of such a process should then determine longevity and be genetically controlled, as can be derived from the species specificity of maximum lifespan. The genome of the somatic cell is a major candidate to study for loss of DNA sequence integrity during aging. Unfortunately, a lack of adequate techniques has thus far...
