Figure Lengend Snippet: Ly6C lo CX 3 CR1 hi macrophages directly accelerate hepatocyte proliferation in vitro . ( A ) Schematic of the experimental design. Normal hepatocytes (HCs) were co-cultured with the CM from 24 h Ly6C hi CX 3 CR1 lo macrophages or 72 h Ly6C lo CX 3 CR1 hi macrophages. ( B ) Representative images of hepatocytes pulsed with EdU and the quantification of hepatocyte proliferation are shown. Scale bar, 50 μm. ( C ) Differential expression of the indicated genes measured by qPCR in 24 h Ly6C hi CX 3 CR1 lo macrophages and 72 h Ly6C lo CX 3 CR1 hi macrophages, presented relative to Gapdh . ( D ) Hepatocytes were co-cultured with the CM from 72 h Ly6C lo CX 3 CR1 hi macrophages or supplemented with the c-Met kinase inhibitor PHA665752 (2.5 μM). Representative images of hepatocytes pulsed with EdU (left panel) and the quantification of hepatocyte proliferation (right panel) are shown. Scale bar, 50 μm. The data shown are representative of at least two independent experiments (n = 3/group). The results represent means ± SEM (*p < 0.05, **p < 0.01, ***p < 0.001).
Article Snippet: Hepatocytes were treated with macrophage-derived CM or HGF (50 ng/ml, Peprotech) for 12 h, followed by EdU (5-ethynyl-2′-deoxyuridine, 20 μM) pulsing for an additional 36 h. In another series of experiments, isolated hepatocytes were treated with Ly6C lo CX 3 CR1 hi macrophage-derived CM supplemented with or without the c-Met kinase inhibitor PHA665752 (2.5 μM, R&D systems).
