Figure 4. Sibling contributions to brain microglial populations vary across an animal’s brain areas.
Contributions of sibling(s) to the microglial populations ascertained in principal brain areas (A), and finer-scale brain substructures (B). CJ001, CJ023 and CJ028 were part of a triplet litter and the chimerism contribution of each twin is shown in a separate panel. CJ102 was profiled in only one brain region and hence was not included in the analysis. y-axis: fraction of twin cells. Vertical bars: binomial confidence interval (95%); P-values: test of heterogeneity across an animal’s brain regions.
