Table 2.

Percentage of labeled epithelium following transfection, electroporation or adenoviral infection. The percentage of epithelial cells labeled represents the average counts from 100 cells over five fields from three different buds.

	% explants with any expression	% explants with epithelial expression	% epithelial cells
GeneJuice	75 (3/4)	0 (0/4)	0
Electroporation	73.8 (31/42)	11.9 (5/42)	0.9 ± 0.3
AdLacZ - Dispase	100 (24/24)	25 (6/24)	2.3 ± 1.3
AdLacZ + Dispase	100 (25/25)	68 (17/25)	29.1 ± 1.1***

*** p < 0.001. One-way ANOVA (non-parametric). SEM given for % epithelial cells labeled.
