Liver sections from ACLF rats 12 and 24 h post-hUC-MSC transplantation or 0.9% sodium chloride injection as a control were used for immunohistochemical staining of AFP, CK18, HGF, and PCNA and microscopic examination (n = 4/group). Representative photographs are shown (a). Positive staining was quantified and is presented as the mean ± SD (b, c). d Serum levels of HGF were detected by ELISA (4h, n = 3/group; 12h and 24h, n = 4/group).
