Figure 7

Comparison of CAIX and CAXII expression during human development. There is no correlation between CAXII and CAIX expression. CAXII positive cells were distributed in taste buds and the submucosal gland of the tongue (A, 17W), the acinar cells of the pancreas (B, lower panel, but not ductal cells [B, upper panel]), the parietal cells but not columnar cells of the stomach (C1, 27W), the large intestine (D1, 17W), the distal tubules and collecting ducts of the kidney (E1, 8W), the choroid plexus (F1, 8W) and the remnants of mesonephric ducts of the ovary (G, 13W). In contrast, CAIX positive cells were seen in the gastric columnar cells (C2, 27W), the ependymal cells (F2, 8W), and the surface epithelial cells of the ovary and peritoneum (H, 13W). However, CAIX expression was not seen in the large intestine (D2, 17W), kidney (E2, 8W) and the remnants of the ovarian mesonephric ducts (H, 13W). W = gestational age in weeks. Original magnifications: A, F1 and F2 (20×); B, C1, C2, D1 and D2 (40×); E1, E2, G and H (10×).
