Fig. 4

Lethally-irradiated B6 mice were grafted with a 1:1 mixture of B6 and B6D2F1 bone marrow and co-injected with WT or HP1α KO (a, b) or SUV39H1 KO (c, d) naive CD4+ T cells alone or in the presence of ex vivo expanded WT Treg. To control engraftment, a group of mice was also injected solely with the bone marrow cell mixture. a, c Representative dot-plots showing the frequency of syngeneic (H-2Kb+) and semi-allogeneic (H-2Kbd+) cells in the blood 21 days after engraftment. b, d Percentage of semi-allogeneic (H-2Kd+) cells among PBMC 21 days after engraftment. Data show mean ± SEM of 3 to 8 independent experiments. Each symbol represents the mean of an experiment. P values were calculated using multiple unpaired t test with Holm-Šidák correction.
