A cohort of 14 mice were given 4NQO in their drinking water for 16 weeks at which time they were converted to regular drinking water until week 21. White light and ratiometric fluorescent (RF) imaging was done biweekly starting at 11 weeks, continuing until week 21 at which time tissue was collected for histological analysis. Cohort 2: A cohort of 16 mice were given 4NQO in their drinking water for 16 weeks followed by single time point imaging and tissue collection at week 16 (n=8), week 18 (n=4) and week 21 (n=4).
