Figure 2. Purinergic- evoked oscillatory calcium transients in sustentacular cells.
(A) Multiple applications of 10 μM UTP produce similar changes in intracellular calcium. ▲indicates time of UTP superfusion. In this figure and all subsequent figures, breaks in traces correspond to time when images were not collected. (B) Average normalized peak calcium transient amplitudes are not different from the predicted peak amplitude for the second application (□, mean ± s.e.m). (C) Representative traces showing oscillatory calcium transients evoked by the superfusion of 10 μM purinergic agonists ATP and UTP.
