Figure 2. Muscarinic receptor-induced sinusoidal Ca2+ oscillations in mouse lacrimal cells.

Figure 2

Top: A single, fura-2-loaded mouse lacrimal acinar cell was exposed to 0.5 μM methacholine (MeCh) inducing sinusoidal Ca2+ oscillations on an elevated basal level of Ca2+. MeCh-induced oscillations occur over a narrow concentration range, and with frequencies that are relatively constant at different agonist concentrations (Bottom figure). These findings were originally published in [46].
