Figure 9.

(A) Lucifer yellow fluorescence emission averaged over the cell body of (first order) cells (gray solid lines, n = 5) adjacent to the injected cell and normalized to the maximal fluorescence emission detected in the injected cell (black solid lines); data are mean values ± SEM (dot lines) for n = 8 cells in each condition. (B) For each experiment, the interpolating line of the curve related to first order cells (with computed slope m₂) and to the injected cell (with computed slope m₁) was computed over the first 10 s of recording. Histograms show mean values of the ratio between m₂ and m₁ for WT (Panx+/+, dashed bars) and Panx1−/− mice (filled bars). Error bars represent SEM.
