Individual effector/regulatory T cell ratio pre-osteotomy determines the healing outcome in mice. (A) Mice having a lower pre-surgery CD8+ TEFF to CD4+ TReg ratio (left y-axis) showed a higher BV/TV (right y-axis, axis is reversed for a clearer depiction). Dashed line indicates the cut off between the +TReg responder (below the dashed line) and the +TReg non-responder (above the dashed line). (B) Adoptive CD4+ TReg transfer did not reshape the unfavorable CD8+ TEFF/CD4+ TReg ratio. (C) Engraftment of CD4+CD25++ T cells 1 d post-surgery is elevated in both, the +TReg responder (n = 4) and +TReg non-responder (n = 3) in comparison to the control group (n = 6). 45BV, total bone volume; TV, total callus volume; BV/TV, ratio of BV to TV; Mann–Whitney U-test.
