Liver histology.
a. Histological analysis with H&E staining at day 0, 0 w (upper row) and each time point after PH transplantation in Sham (second row), Auto (third row), and Allo (lower row) models. Arrowheads (↑) indicate the apoptosis-like cells. Magnification of objective × 20 (scale bar: 20 μm)
b. Histological analysis stained with Azan at day 0 (upper row), 0 w(second row) and 8 weeks after transplantation in Sham (third row), Auto (fourth row), and Allo (lower row) models. 4 × objective's scale bar: 200 μm, 20 × objective's scale bar: 20 μm. The graph shows the Azan-positive area measured by the Image J software. *p < 0.05. n = 3 in each group.
c. Histological analysis stained with PCNA at day 0 (upper row), 0 w(second row) and 8 weeks after transplantation in Sham (third row), Auto (fourth row), and Allo (lower row) models. 4 × objective's scale bar: 200 μm, 20 × objective's scale bar: 20 μm.
