Figure Legend Snippet: Figure 1. Limited bone marrow homing of IL15-iNKs could be rescued by overexpression of CXCR4. (A) RNA-seq reveals the transcriptional level of chemotaxis-associated genes in PBNKs, iNKs, and IL15-iNKs (n = 6 for each group). Statistical significance was determined by one-way ANOVA or Kruskal-Wallis analysis, and Tukey test was used to analyze the specific difference group by group. (B) Flow cytometry analysis of CXCR4 expression on PBNKs, iNKs, and IL15- iNKs. (C) Experimental design to evaluate CXCR4 function in bone marrow (BM) homing using IL15-iNKs. IL15-iNKs were transduced with CXCR4 or luciferase (control), then infused into NOG mice for pharmacokinetic analysis (n = 5 for each group). Two groups of mice were euthanized to obtain BM from femur at day 7 (n = 2) and day 14 (n = 3). BM was resuspended by 200 μl phosphate buffered saline (PBS) for further analysis. (D) Pharmacokinetics of iNKs by detecting CD45+ CD56+ cells in the same volume of peripheral blood (left) and BM (right) at day 7 and day 14 using flow cytometry. Statistical significance was determined by unpaired t test. Data are presented as mean ± SD (D). *P<0.05, **P<0.01, ***P<0.001, ****P<0.0001; ns, no statistical significance. Abbreviations: CXCR4, C-X-C chemokine receptor type 4; iNK, iPSC-derived natural killer cell; PBNK, peripheral blood NK cell.
Techniques Used: Over Expression, RNA Sequencing, Chemotaxis Assay, Flow Cytometry, Expressing, Transduction, Luciferase, Control, Saline, Drug discovery, Cytometry, Derivative Assay
Figure Legend Snippet: Figure 2. Overexpression of CXCR4 affects hematopoietic differentiation of iPSC. (A) Diagram of engineering iPSC with varying levels of CXCR4 expression and their iNK differentiation. (B) Flow cytometry analysis of CXCR4 expression on edited iPSC. (C) Representative images of embryoid bodies (EBs) formed by different iPSC groups at day 9. (D) Flow cytometry analysis of hematopoietic stem and progenitor cell (HSPC) markers (CD43 and CD34) on cells isolated from EB. The gating strategy was built to exclude the isotype staining strictly. (E) Final iNK (CD56+ ) yields from CXCR4low iPSC clones (n = 3) and control iPSC clones (n = 2), demonstrated as final iNKs from each starting iPSC cell. (F) Flow cytometry analysis of CXCR4 levels on iNKs of different groups. (G) Cytotoxicity analysis of CXCR4low iNKs and control iNKs by targeting GFP-labeled THP-1 tumor cells at a 3:1 Effector-to-Target (E:T) ratio in an IncuCyte-based functional assay. Data are presented as mean ± SD (D,E,G). Abbreviations: CXCR4, C-X-C chemokine receptor type 4; iNK, iPSC-derived natural killer cell.

Figure Legend Snippet: Figure 5. Regulatable CXCR4 in iPSC-derived NKs enhances BM homing and completely eradicates residual tumor in the BM. (A) Time schedule of in vivo functional evaluation of CXCR4GZMB-iNKs using THP-1-luciferase xenograft models. (B) Ex vivo bioluminescence imaging of femur to evaluate tumor burden of each group in the THP-1-luciferase xenograft models. After tumor inoculation, mice, untreated (n = 3), or treated with BFPGZMB-iNKs (n = 5) or CXCR4GZMB-iNKs (n = 5) were all euthanized at day 21 to obtain femurs. (C) Luminescence quantification of ex vivo femur shown in panel D. (D) Residual THP-1 cells in BM analyzed by droplet digital PCR (ddPCR). (E) Distribution of iNKs in PB and BM (obtained from femur) detected at day 10 and 21, respectively. Technically, the cells extracted from BM were resuspended in the same volume of PBS between BFPGZMB-iNKs and CXCR4GZMB group. Left, Mann–Whitney U (D10) or unpaired t test (D21); right, unpaired t test with Welch’s correction. (F) Biodistributions of CXCR4GZMB-iNKs and BFPGZMB-iNKs in various tissues, including heart, liver, spleen, lung, kidney, BM, and PB. ‘Distribution index’ was determined as tissue-infiltrated iNKs detected by ddPCR and then normalized to the levels in PB. Values are presented as mean ± SD (C–F). Analyses of differences between groups were performed using Mann–Whitney U test (C,D,F). *P<0.05, **P<0.01; ns, no statistical significance. Abbreviations: BM, bone marrow; CXCR4, C-X-C chemokine receptor type 4; GZMB, granzyme B; iNK, iPSC-derived natural killer cell; PB, peripheral blood.
