Loss of calcein from cultured porcine NPE. Cells loaded with calcein were incubated for 30 min in control medium, calcium-free medium or calcium-free medium containing 18α-glycyrrhetinic acid (100 M). Calcein that remained in the cells was quantified by measuring fluorescence. The values are the mean ± SE of results from 4-11 independent experiments. *** indicates a significant difference (p<0.001) from control, ## indicates a significant difference (p<0.01) from calcium-free condition.
