Figure 4.

The membrane capacitance and the cell radius of a trypsin-treated cell examined with the long staircase waveform (3.5 s long with 100-ms steps) at pipette pressure 0.5 kPa. Data points are from the same cell as shown in Fig. 2. (A) The values for the membrane capacitance obtained with the ascending (▹) part of the waveform are smaller than those obtained with the descending (◃) part, resulting in hysteresis in the voltage dependence. (B) The cell undergoes radius reduction up to 1% during the long waveform (□).
