a ELISA assay of VEGFA in clinical NAFLD- or HBV-fibrosis tissues (NAFLD, n = 7; HBV, n = 12). b Representative Sirius red staining in liver sections from (a). Scale bars, 150 µm. c Quantification of the fibrosis grade according to Ishak score of (a). d Correlation between the expression of VEGFA and fibrosis markers, α-SMA, TGFB1, TIMP1, and MMP2 in (a). The Pearson correlation coefficient was calculated between two variables. e Representative immunofluorescence staining of VEGFA, E-cadherin, and α-SMA in (a). Scale bars, 25 µm.
