Histopathological recovery of liver tissues from ACLF rats transplanted with hUC-MSCs. ACLF 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 and microscopic examination (4h, n = 3/group; 12h and 24h, n = 4/group). Representative photographs are shown for the liver histological presentations of ACLF rats transplanted with hUC-MSCs or 0.9% sodium chloride as a control at hours 4, 12, and 24
