Histological analysis of hFSSC secretome reduced liver fibrosis and promoted liver regeneration. a Photomicrographs of liver tissue sections showing IHC staining for α-SMA, PCNA, and HNF-4α. Brown cells represent the positive expression, bar = 1 mm. b–d The quantification of α-SMA, PCNA, and HNF-4αpositive cells area. *p < 0.05, **p < 0.01, ***p < 0.001. n = 10, mean ± SD
