See also Figure S4A, B . (D) Long-term killing assay (E:T 1:10) of all CAR-CIK cells against primary AML blasts (n=8 blasts) compared to NT cells. Blasts survival was determined by flow cytometry (n=13 donors). (E) Recovery of LSC-enriched CD34 + CD38 - population (n=8 patient samples) after 7 days co-culture with all CAR-CIK cells (E:T 1:10), compared to NT cells (n=13). Data are presented as individual values and the mean ± SD. Statistical significance was determined by one-way ANOVA test. ** p<0.01, **** p<0.0001. Illustrations were created with Biorender.com. See also Figure S4 for expression and phenotypic characterization of Dual CAR constructs, Figure S5 for Dual CAR-CIK cell activity against AML cell lines and Figure S6 for Dual CAR-CIK cell off-tumor toxicity against healthy immune and hematopoietic cells.

( E, J ) Leukemic burden in spleen (left) and PB (right) evaluated by flow cytometry, in low- (E) and (J) high-burden models. Illustrations were created with Biorender.com. Results represent two independent experiments using CAR-CIK cells generated from 2 donors. Data are presented as individual values and the mean ± SD. Statistical significance was determined by one-way ANOVA. **p < 0.001, ***p = 0.0001 and ****p < 0.0001.
