Figure 4.

BrdU labeling in the gastric mucosae of H₂O control (A), erosion-induced (B) and DSF-pretreated then erosion-induced (C) mice. The tissues were counter-stained with PAS to show mucus-secreting pit cells at the luminal surface. (D) Counts of the BrdU-labeled cells in control, erosion-induced and DSF-pretreated then erosion-induced mice (n = 3 per group) are presented as mean ± SE. In this figure and all following figures, asterisks above columns indicate significant difference when the value of that column is compared with the H₂O control. Asterisks above the line indicate differences between adjacent groups ** p < 0.01, *** p < 0.001; scale bar = 100 µm.
