Integrated single-cell and bulk-tissue transcriptomic analysis reveals an epithelial-stromal inflammatory microenvironment in biliary atresia
Background Biliary atresia is a severe fibroinflammatory cholangiopathy of infancy. Its pathological process involves biliary epithelial injury, immune activation, and intrahepatic stromal remodeling, but the cellular interactions linking these processes remain incompletely defined. Using public single-cell and bulk-ti...
