The magnitude of the hydrostatic pressure-induced [Ca2+]i increase in cells bathed either in nominally calcium-free medium or in the presence of 4 mM nickel chloride in calcium-containing medium. (A) Record of [Ca2+]i concentration measured over time. (B) Changes in [Ca2+]i concentration measured 15 minutes after the onset of the pressure increase. Results are mean ± SEM of 4 to 6 independent experiments. [Ca2+]i was measured every 10 seconds, but for clarity the SEM values are only shown at 1-minute intervals in (A).
