Supplementary Figure S1 from Neutrophils Mediate Protection Against Colitis and Carcinogenesis by Controlling Bacterial Invasion and IL22 Production by γδ T Cells

Figure S1. Neutrophil deficiency is associated with increased lymphoid aggregates. Related to Figure 1.A) Number of total lymphoid structures and B) number of lymphoid structures with follicular dendritic cells detected by RNAscope staining for the follicular dendritic cell marker Mfge8 in colon tissue sections from Csf3r+/+(n=8) and Csf3r-/- (n=5) mice after AOM/DSS-induced CRC. C) Representative images of RNAscope analysis for Mfge8 in colon tissue sections from Csf3r-/- mice after AOM/DSS-induced CRC: aggregates with follicular structures are visible as Mfge8+ (red spot): on the top is visible a lymphoid aggregate at two different magnifications, with diffuse Mfge8+ cells; on the bottom right lymphoid microaggregate with Mfge8+ cells; on the bottom left aggregate without follicular structures (Mfge8+). D) Representative dot-plot of neutrophils frequency in blood (top panels) and colon LP (bottom panels) of Csf3r-/- mice and Csf3r-/- mice 4hrs and 18hrs after adoptive transfer of neutrophils. E-F) Frequency of neutrophils in blood (D) and colon LP (E) of DSS-treated Csf3r-/- mice (n=5) and Csf3r-/- mice 4hrs (n=5) and 18hrs (n=5) after adoptive transfer of neutrophils. A-B) Representative data of three independent experiments. C-E) One experiment. A-B, D-E) Unpaired Student’s t-Test. Data are mean ± SEM. *** p < 0.001 ** p < 0.01 * p < 0.05.
