English: A–D: Dye diffusion patterns after PI was injected into a single cell in various locations in the cochlea. The type of the cells that was injected is given at lower right corner of each panel. E–F: Diffusion patterns of four different fluorescent dyes after injecting into a single Claudius cell. Name of the dye is given in the lower right corner of each panel. Panels B), C), D), F) & H) were photographed with unfixed fresh samples. Panels A), E), G) were results obtained from fixed samples after the experiments were done. They were labeled with fluorescent phalloidin (red in E, green in A&G) to outline the cell border. Scale bar on the top left of each panel represents approximately 100 µm.
