CCR6 controls the thymus homing of peripheral Foxp3⁺ T‐Reg. panel (A) shows flow cytometry analysis of splenocytes obtained from CD45.1⁺ WT mice previously grafted with either CD45.2⁺ WT (white bars) or Ccr6^−/− (black bars) embryonic thymus lobes. Graphs show the absolute numbers of indicated donor cell populations. Panel (B) shows similar analysis of graft‐derived donor cells in the host thymus harvested from the same mice. Error bars indicate SEM using an unpaired Student's two‐tailed t‐test: ^* p < 0.05; ^*** p < 0.001. Data are representative of at least two separate experiments, with at least 5 mice of each strain in total.
