Macroscopic junctional conductance after 24 h of plating.A: uncorrected mean macroscopic electrical conductance (gj) measurements (filled bars) with corresponding mean series resistance (Rs) values (open bars) for wtC1 [wild-type connexin (Cx)43 (Cx43-wt); n = 9], wtS1 (Cx43-wt and v-Src; n = 13), wtS3 (Cx43-wt and v-Src; n = 12), and dbS2 [Cx 43 with Y to F substitutions at 247, 265 (Cx43-Y247,265F) and v-Src; n = 9]cell pairs. B: corrected mean g
j values for each cell type. v-Src expression was sufficient to reduce gj in wtS1 and wtS3 cells. *Significant difference from wtC1 (P < 0.05).
