a Upper panel: schematic diagram of in vitro migration assay; lower panel: representative fluorescence images captured by live imaging system showing the movement of EGFP-hEnSCs and DiI-Ac-LDL-labeled MoMFs/Kupffer cells. b Left: schematic diagram of intravital microscopy used to monitor in vivo interactions between hEnSCs and MoMFs/Kupffer cells; right: representative fluorescence images captured by live confocal microscope showing the interactions between EGFP-hEnSCs (pink arrows) and F4/80-PE-stained MoMF/Kupffer cells (blue arrows), and the interactions between EGFP-hESCs (yellow arrows) and F4/80-PE-stained Kupffer cells (blue arrows). c qRT-PCR showing expression of the indicated ISGs in the monocyte/MoMF/Kupffer cell populations cocultured with or without hEnSCs. The monocyte/MoMF/Kupffer cell populations were isolated from ALF rat livers at 24 h post D-GalN treatment, and were cocultured for 3 days with an initial seeding ratio of 1:1 in the presence or absence of rat recombinant IFNγ. Values were determined relative to Tbp. n = 3 independent samples for each group. Tukey’s multiple comparisons test was used to calculate significance between groups. ns, no significance; *P < 0.05; **P < 0.01; ***P < 0.001; ****P < 0.0001.
