A. Weight changes of mice fed regular chow or MCD during 6 weeks period. In each group, the number of mice was n = 6. **p < 0.01. B. Photographs of liver sizes of mice from different experimental groups (upper panel). The weights of each group of mice were recorded and counted (n = 6, below panel). **p < 0.01. ns: not significant. C. Plasma levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) of each mouse were recorded and counted (n = 6 in each group); *p < 0.05; D. Representative images of HE-stained liver sections of the indicated groups (microscope 40×). a mice with regular chow; b mice with MCD; c mice with MCD and intervention with control medium (CM) extract twice a week; d mice with MCD and intervention with hUC-MSC exosomes(Ex) twice a week. Scale bar = 50 μm. E. Pathology scores for balloon-like degeneration, steatosis, and lobular inflammation of groups of liver sections (n = 6). *p < 0.05, **p < 0.01
