Fig 4. BrdU index (BrdU+ cells/total cells) in fungiform and circumvallate papillae.
Mean±SEM BrdU index values for fungiform (top) and circumvallate (bottom) papillae at 0, 4, 8, 10, 12 and 16 days post CYP injection (n = 6 mice/group). The BrdU index values for both papillae were significantly lower than control (0 days) at 4 days after injection. BrdU index values for circumvallate papillae were significantly greater than controls at 8 days after CYP injection. * P<0.05.
