Although cell type-specific assignment was not possible for several genes, some of them had already been attributed to non-PSC liver fibrosis such as CTHRC128 or to non-liver fibrosis such as SFRP4. 29,30 We also found TMEM178B, which has recently been discovered as being upregulated in biliary fibrosis in people with biliary atresia.31 This evidence concerns the gene TMEM178B and Hepatic fibrosis.
