Histopathological recovery of liver tissues from rats with ACLI transplanted with hUC-MSCs. ACLI rats were transplanted with hUC-MSCs or 0.9% sodium chloride as a control, and liver sections were used for histological investigation with HE staining (a) or Masson staining (b) and microscopic examination (n = 3/group). Representative photographs are shown for the liver histological presentations of rats with ACLI transplanted with hUC-MSCs or 0.9% sodium chloride as a control at weeks 0, 1, 2, 4, and 6
