Percentage of all end cells formed by the 3 Cx43 genotypes of fetal liver and assayed at different intervals after grafting.

The 3 Cx43 genotypes are compared, each raced against the same dose of host fetal liver. Box-and-whiskers figures of the proportions of the pooled 5 end cells between 21 and 131 days after grafting are shown. No donor genotype is consistently advantaged. With the passage of time (out to 6 months, not shown here) Cx43^+/−fetal liver formed more end cells than either WT or KO. This will be reported elsewhere (M.R. and M. Stone, manuscript submitted).
