Differential expression of a BMP4 reporter allele in anterior fungiform versus posterior circumvallate taste buds of mice

Table 1 New cell entry is comparable in circumvallate and fungiform taste buds

Time post-BrdU injection	Number of circumvallate taste bud profiles (number of mice)	Number of circumvallte taste bud profiles with BrdU-IR cells	Mean number of BrdU-IR cells per taste bud profile +/- SEM (for all cvp taste buds)	Number of fungiform taste bud profiles (number of mice)	Number of fungiform taste bud profiles with BrdU-IR cells	Mean number of BrdU-IR cells per taste bud profile +/- SEM (for all ffp taste buds)
24 h	37(3)	225	0.72 +/- 0.04	52 (3)	28	0.66 +/- 0.1
48 h	314(3)	230	0.89 +/- 0.05	52 (3)	30	0.67 +/- 0.1
72 h	245 (3)	139	0.66 +/- 0.09	61 (3)	38	0.66 +/- 0.09

The number of BrdU-IR cells inside taste buds per taste bud profile at 24, 48, and 72 hours post-injection (mean +/- standard error, n = 3 mice for each time point). There is no statistical difference between the number of new cells at any time point between the circumvallate and fungiform taste buds (p > 0.05 by t test for each time point post BrdU injection).
