Redistribution of NBCe1 and NKCC1 in OH⁻-saline pH 8.0 or HCO₃⁻-saline pH 8.0-treated rat jejunum. Neighboring ligated proximal jejunal segments were treated with OH⁻-saline pH 8.0 (left) or HCO₃⁻-saline pH 8.0 (right). A–B: tissue sections double-labeled for NBCe1 (green) and NKCC1 (red). C–D: high-powered micrographs of NBCe1/NKCC1 double-labeled in villus section. Open arrowheads, intracellular NKCC1 label; open arrow, basolateral NBCe1 label; arrow, basolateral NKCC1 label; G, goblet cell. Scalebars: A–B, 50 μm; C–D, 10 μm. The images represent the results of 4 experiments (n = 4).
