摘要: Background The ability to discern ancestral relationships between individual human colon crypts is limited. Widely separated likely trace their common ancestors a time around birth, but closely spaced adult may share more recent if they frequently divide by fission form clonal patches. Alternatively, be long-lived structures that infrequently or die.
