a, Flow cytometric analysis of pluripotency marker expression on H1, FiPS and WT-TiPS b, Flow cytometric analysis of T lymphoid markers of H1, FiPS and WT-TiPS during differentiation on OP9-mDLL1 at indicated timepoints. Plots depicting CD7/CD5 are gated on live CD45+ cells, plots depicting CD3/TCRαβ, CD4/CD8α and CD8α/CD8β are gated on live CD45+CD7+ cells. CD3/TCRαβ and CD4/CD8α at D40 are as presented in Fig. 1b.
