Dynamics of glutamine synthetase expression in hepatic ischemia-reperfusion injury: Implications for therapeutic interventions

Figure 1 The distribution of glutamine synthetase in normal liver. A: Schematic illustration of liver zonation; B: Liver tissues from C57BL/6J mice were processed for hematoxylin and eosin staining. Scale bar: 100 μm; C: Liver tissues from C57BL/6J mice were processed glutamine synthetase immunofluorescence staining (green). Scale bar: 100 μm. Representative images are displayed, with six mice in each group. The experiment was repeated at least three times to ensure reproducibility and reliability of the results. PV: Portal vessels; CV: Central vessels; GS: Glutamine synthetase; HE: Hematoxylin and eosin; IR: Ischemia-reperfusion.
