Figure 1From: Ca2+-signaling in airway smooth muscle cells is altered in T-bet knock-out miceAppearance of acetylcholine-induced airway contraction in lung slices. The phase-contrast micrographs show an airway in a lung slice from a T-bet KO-mouse (A) immediately before, (B) 10 sec and (C) 90 sec after the addition of 10-7 M ACH. Bar: 30 μm [see additional file 1].Back to article page
