Outer hair cell
The cell was stained with a calcium-sensitive fluorescent dye, fluo-3 AM. Notice the bundle of stereocilia standing like tin soldiers on the upper surface of the cell. Picture by Dr. C. Harasztosi using the confocal laser-scanning microscope. With this set-up we are performing Ca²⁺ imaging experiments, membrane re-cycling observations and morphological studies. © 2005 A. W. Gummer.
