Figure Lengend Snippet: NSG-Quad mice promote the development of tumor-infiltrating human macrophages (A) Tumor growth curves in NSG ( n = 9), NSG-Quad ( n = 12), and MISTRG-6 mice ( n = 15) engrafted with SW480 CRC cells and in NSG ( n = 10), NSG-Quad ( n = 4), and MISTRG-6 mice ( n = 14) engrafted with HCT116 CRC cells. (B) Frequency of hCD45 + cells in the tumor of NSG, NSG-Quad, and MISTRG-6 humanized mice engrafted with SW480 or HCT116 CRC cells (10–15 weeks post-engraftment with human-cord-blood-derived CD34 + cells; end of experiment). (C) Human immune cell composition in the blood of NSG, NSG-Quad, and MISTRG-6 humanized mice engrafted with SW480 or HCT116 CRC cells (10–15 weeks post-engraftment with human-cord-blood-derived CD34 + cells; end of experiment; data from G). (D) Human immune cell composition in the tumor xenografts of NSG ( n = 9, SW480; n = 10, HCT116), NSG-Quad ( n = 10, SW480; n = 3, HCT116), and MISTRG-6 mice ( n = 15, SW480; n = 12, HCT116). (E) Representative IHC pictures show SW480 CRC-infiltrating human CD68 + macrophages in NSG, NSG-Quad, and MISTRG-6 humanized mice. Scale bar: 50 μm. (F) Frequency of human CD68 + macrophages in CRC xenografts of NSG ( n = 11), NSG-Quad ( n = 7), and MISTRG-6 mice ( n = 15) analyzed by IHC. (G) Frequency of CD86 + (M1-like) and CD163 + (M2-like) human CD14 + monocytes in SW480 and HCT116 CRC xenografts of NSG-Quad ( n = 13) and MISTRG-6 mice ( n = 17). (H) Composition of the human CD33 + CD66b − myeloid cell population based on the expression of CD14, CD16, and HLA-DR in SW480 CRC xenografts of NSG-Quad ( n = 8) and MISTRG-6 ( n = 3) mice. Data are shown as mean ± SEM. p values were calculated using one-way or two-way ANOVA (G) with Tukey’s multiple comparison test. ∗ p < 0.05, ∗∗ p < 0.01, and ∗∗∗ p < 0.001.
