Figure Lengend Snippet: a , Timeline of the first animal study using NOG-hIL-15 (NOG15) mouse ( s.c. , i.p. and i.v. stand for subcutaneous, intraperitoneal and intravenous, respectively). b , Table showing specific amount of cells used for three dosings (see a ) in the humanized animals. c , Human leukocyte antigen (HLA) haplotype information for PBMC donor 416C (green) and 202C (magenta). Note that 416C is HLA-A2-positive. d - f , Data from the humanized mouse study showing tumor volume ( d ), the percent of human CD45 (hCD45) positive cells over total CD45 + cells (hCD45 + plus mCD45 + ) ( e ), and the amount of human hCD45 + /hCD3 - /hCD56 + NK cells ( f ) (see for flow cytometric gating strategy and percent/events conversion). A dotted line in d indicates that mice were supposed to be euthanized when the tumor volume was larger than 3000 mm 3 . Note that mouse 18019 was not euthanized on day 17 hoping the injected CAR-T cells might reduce tumor volume below 3000 mm 3 after the second dosing. A dotted line in e indicates a 20% hCD45 reconstitution cutoff. g , Flow cytometric analysis for hCD45 + cells in peripheral blood collected from mouse 18025 and 18023 on day 20 and 24. See also .

Figure Lengend Snippet: | In vivo assessment of hypoimmunogenic iT cells using an hIL-15-NSG mouse. A , Experimental timeline. Human NK cells (donor #4) were mixed with parental or dKO iT cells at a 1:1 ratio, or with medium alone (control), and co-injected intraperitoneally into hIL-15-NSG mice. B , Bioluminescence imaging was performed at 2, 3, 4, and 7 days post-injection using IVIS. W/O = without; W/ = with. C , Quantification of total bioluminescence at the indicated time points. Relative survival ratios were calculated as the bioluminescence signal of iT cells co-injected with NK cells divided by the signal from iT cells injected without NK cells. P values were determined using a two-tailed, unpaired t -test. Data are mean ± s.d. (n = 4 per group).
