Extended Data Fig. 1. The CAR construct impacts the differentiation of CAR-iPSCs into T-cell lineages.

Extended Data Fig. 1

a. CD19 expression on iPSCs, hematopoietic progenitor cells, and T-cell lineages in the differentiation process. The CD19 expression on PBMCs is indicated as a reference (right). b. Hematopoietic progenitor cells derived from inducible 1928z CAR-transduced T-iPSCs were divided into two groups and subsequently differentiated into immature iCAR-T in the presence (2 μg/mL) or absence of doxycycline (Dox). Surface antigen expression of CD3, CD45, CD5, CD7, CD4, CD8a from the two groups is shown. HSPC, hematopoietic stem progenitor cells. c,d. Inducible 1928z CAR-transduced T-iPSCs were differentiated into immature iCAR-T cells without Dox and cultured for 1 more week in the presence or absence of Dox. The expression profile of CD4 and CD8β (c) and o NK-cell-related surface antigens (d) are indicated. N = 3, mean ± SEM, statistical tests. Two-sided Student’s t test. MFI, mean fluorescence intensity, SEM, standard error of the mean.
