Minimal bystander toxicity of clinical CD33 chimeric antigen receptor construct (CD33CART) product. (A) 1×105 GFP-transduced T cells ((-)TC) or clinical-grade lintuzumab-CD28/CD3ζ (lin-28z) cells were co-incubated in a 1:1 ratio with induced pluripotent stem cell lines of the designated normal tissue types for 18 hours. IFN-γ levels were quantified by ELISA in the culture supernatant as in figure 2. MOLM14 cells were used as a CD33 +positive control. No appreciable cytokine production was detected in any of the normal tissue conditions.
