FSTL1 expression in chronic liver diseases. a Serum concentrations of FSTL1 in healthy CTL (n = 27) and patients with HBV (n = 19), LC (n = 4) and HCC (n = 15). b Paraffin liver sections from healthy CTL, and patients with HBV and LC were stained with FSTL1 (red), α-SMA (green) and DAPI (n = 5 per group). Scale bar: 100 μm. HBV, Viral Hepatitis B; LC, Cirrhosis; HCC, hepatocellular carcinoma. c FSTL1 expression in human liver tissues was examined in a published gene-profiling dataset (GEO: GSE31803). The degree of liver fibrosis is divided into mild (n = 40) and severe forms (n = 32). Throughout, data represent mean ± SEM. ***P < 0.001
