First, we tested the combination of Ven/Aza and WT1-TCB in vitro in cocultures with T cells from nine healthy donors and OCI-AML3 (Fig. 2) or SKM1 cells (Supplementary Fig. 2A, B) for six days in the presence of 1 μg/mL WT1-TCB, 25 nM Ven and 1 μM Aza mimicking concentrations reported for AML patients. Here, WT1 is linked to acute myeloid leukemia.
