Representative photograph of GFP staining of MSCs in each group (n = 10). GFP-labeled MSCs were concentrated in the portal vein region under fluorescence microscopy images (×100, scale bar = 100 μm). a There are almost no GFP positive cells in the liver tissue and portal area of the group I. b There are a small number of GFP positive cells in the portal area of the group II. c There are GFP positive cells in the liver tissue and portal area of the group III. d There are a large number of GFP positive cells in the liver tissue and portal area of the group IV. e Quantitative analysis revealed that transplanted MSC in the group II (5.7 ± 1.26) was significantly increased compared to the group I (1.7 ± 1.09) (P < 0.01) and transplanted MSC in the group IV (31.9 ± 4.58) was significantly increased compared with other groups (P < 0.01). All values are expressed as the mean ± SD. **P < 0.01; n = 10
