• the number of cleaved CASPASE-3-positive small intestine crypt cells is increased at 0, 2, 4, and 7 days after beta-napthoflavone (betaNF) treatment
• the number of BrdU-positive small intestine crypt cells is reduced at day 2 but increased by day 4 post-betaNF treatment

• at day 2 after the last of 5 consecutive beta-napthoflavone (betaNF) injections, small intestine architecture is severely disrupted, with fewer and smaller crypts and shorter, hypocellular and progressively disorganized villi
• however, by day 4 after the last betaNF injection, ORC1 protein levels are restored to nearly normal levels and a 4- to 5-day repopulation period ensues with enhanced DNA replication, progenitor cell proliferation and crypt hypertrophy such that crypt-villus integrity is fully restored at day 7 post-treatment
• at day 2 post-betaNF treatment, fewer and smaller crypts are observed in the small intestine
• however, crypt integrity is fully restored at day 7 post-betaNF treatment
• at day 2 post-betaNF treatment, small intestine villi are shorter, hypocellular and progressively disorganized
