IL-10 expression of mouse peripheral CD8+ lymphocytes incubated with mouse embryo-derived EVs, or with anti-PIBF treated mouse embryo-derived EVs. Anti-CD8 labelled mouse spleen cells were incubated with embryo derived EVs, or with EVs that had been pre-treated with anti-PIBF antibody for 30 mins. Anti-rabbit IgG was used as an isotype control. Then the cells were labelled with anti- IL-10 antibody, and the number of IL-10 positive cells among the subpopulations was determined by flow cytometry. The bars represent the mean+/− SEM of 15 measurements. *p < 0.001.
