||"Interestingly, the small intestine, a tissue with a very high cell
proliferative activity, was found to undergo the largest age-related
increase in mutant frequency among all organs studied, i.e., from
11.0X10^-5 in young mice to 25.6X10^-5 in old mice [BNID 110457]. By
contrast, in brain, a postmitotic organ, there was virtually no such
age-related increase, i.e., from 4.8X10^-5 in young animals to
5.0X10^-5 in old ones [primary source]." "age group: 3–8 months (young), 16–21 months (middle), and 25–34 months (old)."
