DKK3 and Hepatic fibrosis: found that insulin-like growth factor binding prote-3, Dickkopf-3 (DKK-3), and DKK-1 derived from human amniotic mesenchymal stem cells (MSCs) mitigate hepatic fibrosis via suppression HSC activation through blocking Wnt/β-catenin signaling in mice induced by injecting CCl4 via the tail vein.
