Cx43 orchestrates Ca²⁺ signaling at large scales, but not across local neighborhoods, in the stem cell pool. Disrupted Ca²⁺ dynamics in Cx43 cKO mice (K14CreER; Cx43^fl/fl; R26-GCaMP6s) on the right compared to littermate controls (K14CreER; Cx43^+/+; R26-GCaMP6s) on the left, 5 d after tamoxifen induction. 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.
