Adoptively transferred human Vγ2Vδ2 T cells from prostate cancer patients persist in the blood of NOG mice. Vγ2Vδ2 T cells (>98%) were expanded from prostate cancer patient 2 (PC02) (left panels) and patient 4 (PC04) (right panels) and frozen for later use. 5 × 10⁷ thawed Vγ2Vδ2 T cells were then adoptively transferred into each NOG mice. Fifteen days after transfer, peripheral blood was obtained. After RBC lysis, the resulting cells were stained and then analyzed by flow cytometry for expression of Vδ2 TCR and human CD3. Values shown are % of total cells. Mean ± SD PC02 2.5% ± 0.9%, n = 3 PC04 6.4% ± 2.4%, n = 3
