A. Two cells were coupled in the control experiment using 117 mM K+ gluconate-based intracellular solution containing no spermine, while in B. injection of the cell with the same intracellular solution enriched by 1 mM spermine revealed a robust increase in cell-to-cell coupling (18 cells stained total). C. The SPM-induced increase in coupling was abolished in slices pretreated with 200 µM carbenoxolone. Images were taken 10 min after loading the fluorescent dye through the patch pipette. Note the different scale bar in B.
