Dynamic changes of key metabolites during liver fibrosis in rats

Figure 2 Histological assessment in each group using hematoxylin and eosin and Masson’s trichrome staining. A-E: Liver tissues were stained with HE in the control and fibrosis model groups at weeks 1, 4, 8, and 12; F: The injury score of fibrosis in each group; G-K: Liver tissues were stained using MTC in the control and fibrosis model groups at weeks 1, 4, 8, and 12 (^aP < 0.01 vs control). Scale bars: 100 μm. HE: Hematoxylin and eosin; MTC: Masson’s trichrome.
