Biochemical analyses. (a) Alanine aminotransferase (ALT); (b) aspartate aminotransferase (AST); (c) total bilirubin (TBIL); (d) direct bilirubin (DBIL); (e) gamma glutamyl transpeptidase (γ-GT); (f) alkaline phosphatase (ALP); (g) albumin (ALB); (h) laminin (LN); (i) hyaluronic acid (HA). Saline control group rats (group I), untreated fibrosis animals (group III), and fibrotic animals transplanted with hPMSCs (group II) and sacrificed one week, four weeks, eight weeks, or twelve weeks after transplantation (1 w, 4 w, 8 w, or 12 w). (a–g) Group I, n = 20; group II, n = 8; and group III, n = 8. (h–i) Group I, n = 9; group II, n = 8; and group III, n = 8. Data represent the means ± SD and were statistically analyzed by one-way ANOVA. ∗p < 0.05, ∗∗p < 0.01, and ∗∗∗p < 0.001.
