Small intestinal postoperative ileus is induced by Ly6C+ monocytes or Ly6C macrophages. (A–C) Abundance of Ly6CF4/80+ macrophages (MPs) (A), Ly6C+F4/80+ monocytes (B) and Ly6C+CD115+ monocytes (C) after sham (A) or small intestinal manipulation (SIM) in the small intestinal muscularis (B) or in the blood (C) of Cx3cr1-Cre+ iDtrflox/+ (BM-iDTR) or C57Bl/6 (BM-WT) bone marrow chimeras treated with diphtheria toxin (+DT) or left untreated (–DT) (representative data of n=7). (D,E) Measurement of small intestinal motility 24 hours after SIM or sham in Cx3cr1-Cre+ iDtrflox/+ (BM-iDTR) or C57Bl/6 (BM-WT) mice (SIM n=11, SIM DT and CloLip n=7, sham n=4) (FITC-Dex=Fluorescein isothiocyanate-dextran, S=stomach, 1–10=small intestinal segments, Z=caecum, C1-3=large intestinal segments). GC=geometric centre; CloLip=clodronate liposomes. Results are given as mean +/− SEM. *p<0.05; **p<0.01; ***p<0.001.
