Fetus-NSPCs and 2A4F iPSC-NSPCs triggered allogeneic PBMC, but not syngeneic PBMC, proliferation in vitro. Fetus-NSPCs and 2A4F iPSC-NSPCs were irradiated and co-cultured with syngeneic mouse (C57BL6/J) PBMCs and allogeneic mouse (BALB/cA) PBMCs (pre-immunized and post-immunized) at a ratio of 1:10 with or without IFNγ and anti-TGFβ receptor antibodies for 5 days (n = 3 independent experiments). (A,C) CPM measured in MLR assays without (A) or with (C) the anti-TGFβ antibody. (B,D) The SI was calculated as the ratio of the CPM in each MLR assay relative to the CPM in a syngeneic MLR assay. Values are shown as the mean ± SEM. *P < 0.05 and **P < 0.005, unpaired two-tailed Student’s t-test or one-way ANOVA followed by the Tukey–Kramer test. ns = not significant.
