Fig. 4. Laser scanning images (A-C) and corresponding LSC histogram (D) of chloride cells (CC) from killifish exposed to FW, 1x SW or 2.4x SW for 1 week. Image galleries were acquired using the relocation function of the LSC. Cells shown in image galleries represent CC from within the circled areas in Fig. 2A-C. (A) CC from FW fish; (B) CC from 1x SW fish; (C) CC from 2.4x SW fish. (D) Histogram of CC area from fish acclimated to FW (blue), 1x SW (green) and 2.4x SW (red). The arrow points to a population of small cells that may represent accessory cells in the SW groups. Bars, 50 µm.
