Extended Data Fig. 1: In vitro expansion of cell products and ALC post-ACT.

(A) T-cell expansion over time during product manufacturing. Exp T cells: expanded T cells (n=13). (B-C) Correlation between ALCmax observed post-ACT and lowest ALC value (ALCnadir) observed following lymphodepleting chemotherapy and prior to ACT (B), and between highest ALC value observed post-ACT (ALCmax) and T-cell expansion in vitro (C). R2 and p-values were calculated by simple linear regression analysis.
