Basal cells stalled in G2 of their cell cycle show normal patterns of Ca2+ signaling. G2-enriched MMC-treated mice on the right compared to DMSO vehicle-treated littermate controls on the left, 2 d after drug treatment. Magenta marks the nuclei of each basal cell and green fluorescence intensity represents relative cytosolic Ca2+ levels. Frames were taken every 2 s for a total duration of 30 min. Movie shows dynamics at 40 frames per second or 80× the actual timescale. Scale bar: 25 μm.
