Adjusting T-cell numbers in the inoculum results in varying T-cell numbers in the emerging tumors but does not have a detectable impact on fractions of malignant cells or NK cells. (A) Schematic diagram of a humanized mouse model in which mice were inoculated on day 0 with consistent numbers of Raji tumor cells and T-cell–depleted PBMCs but varying numbers of T cells. (B) Flow cytometric analysis of FNAs obtained from mouse xenografts 20 days after inoculation and evaluated for percent of cells that are CD19+, CD56+, or CD3+ (n = 12-15 mice per group).
