Fig. 6. Cells expressing Cx43 S325/328/330A are inefficient at dye transfer. Wild-type (WT)-, parental knockout (KO)- and Cx43-TM (clones TM-A, TM-B and TM-C)-expressing cells were microinjected with Lucifer Yellow dye. After 3 minutes of transfer, digital images were taken and the number of recipient cells was determined (n=the number of injected cells). Bars show the mean and error bars ± s.e.m. The extent of dye transfer was significantly different (^**P<0.02) for WT compared with all of the other cell types.
