Figure Lengend Snippet: a Representative flow cytometry plots gated on CD45 + living cells isolated from colonic lamina propria of WT and Pellino1-mKO male mice in normal, acute 1.5% DSS, and AOM/DSS groups. Migratory macrophages (CD11b + CX3CR1 int ), resident macrophages (CD11b + CX3CR1 hi ). b (Left) Percentage of CD11b + CX3CR1 hi macrophages, (Right) CD11b + CX3CR1 int macrophage infiltration into the colonic lamina propria in WT and Pellino1-mKO male mice in normal, acute 1.5% DSS, and AOM/DSS groups (H 2 O, n = 4; DSS, n = 5; AOM/DSS, n = 5). These percentages for both CD11b + CX3CR1 hi and CD11b + CX3CR1 int were determined by gating among CD45 + cells. c (Left) Representative images of the wound healing assay. Wound healing assays were performed to examine the migration of BMDMs of WT and Pellino1-mKO under stimulation of 100 ng/mL LPS and 20 ng/mL CCL5 for 24 h. Initial wounded areas were marked with a dashed line. Scale bar = 100 μm. (Right) Quantification of migration areas using ImageJ ( n = 4). d (Left) Representative images of the migration assay. BMDMs from WT and Pellino1-mKO mice were induced to migrate with stimulation from 100 ng/mL LPS, 20 ng/mL CCL5, and 100 ng/mL TGF β for 24 h. Scale bar = 50 μm. (Right) Quantification of migrated cells within the field of view area using ImageJ ( n = 7). e (Left) CFSE-labeled MC38 tumor cells were co-cultured with BMDMs from WT and Pellino1-mKO mice for 6 h in the presence of 100 ng/mL LPS. (Right) Phagocytic index was calculated using the following formula: phagocytic index (%) = (number of F4/80 + CSFE + cells)/(number of F4/80 + cells) × 100 ( n = 5). f Expression levels of mRNA associated with macrophage migration in colon tissues of WT and Pellino1-mKO male mice of normal (WT, n = 5; Pellino-mKO, n = 4), acute 1.5% DSS ( n = 6), and AOM/DSS (WT, n = 5; Pellino-mKO, n = 6) groups were assessed by qRT-PCR and normalized to GAPDH expression. Data were represented as mean ± SD in ( b – f ). All statistical comparisons were made using two-tailed Student’s t -test. Source data are provided as a Source Data file.
