Traces of all cells are shown: 0.60 Osmol/kg (blue; N = 15), 0.80 Osmol/kg (green; N = 6), 1.45 Osmol/kg (orange; N = 5), 2.0 Osmol/kg (dark red; N = 10), and 2.5 Osmol/kg (gray, N = 9). (B–D) Individual traces of normalized volume are given for six different cells, one at 0.6 Osmol/kg, two at 1.45 Osmol/kg, and three at 2.0 Osmol/kg hyperosmotic shock. Data points are recorded at 1 Hz during the first 5 min and at 30 s intervals after that. For display, the initial 5 min have been resampled at one frame every 30 s, and only the normalized volume after the shock is displayed for each individual cell (cell volume has been normalized and each individual cell starts at value 1).
