Abstract excerpt
In both large and small intestine, mutagen administration leads to the occurrence of isolated crypts that are completely populated by a mutated phenotype; therefore, it has been proposed that crypts are maintained by a single stem cell. We show in mice that a single dose of mutagen leads to an early transient increase in frequency of colonic crypts that show a partial mutated phenotype and a later increase in...
