Figure 5From: Ca2+-signaling in airway smooth muscle cells is altered in T-bet knock-out miceAppearance of the ACH-induced increase in [Ca2+]c. The pseudocolor 2-photon micrographs show a part of a bronchial wall of an airway in a lung slice. Airway smooth muscle cells (arrows) are separated from the airway lumen (AL) by epithelial cells. (A) shows the airway immediately before and (B) 5 sec after the addition of 10-7 M ACH. "Warmer" colors indicate higher [Ca2+]c. Bar = 10 μm [see additional file 2].Back to article page
