Distribution of the percentage of β-gal+ cells in eight circumvallate taste buds

% β-gal+ cells	6	7	8	9	10	11	12	13	14	15	18
β-gal+/N	4/66		4/48		6/59		6/49	4/30			11/62
					4/40		10/82
# Taste buds	1	0	1	0	2	0	2	1	0	0	1

Nuclei in serial sections through the entire individual taste buds were counted. In some cases, a few cells in the taste bud might have been missed because of unclear taste bud boundaries. Counts did not include perigemmal cells. β-gal+/N, Actual count of β-gal+ cells per total number of cells in that taste bud.
