Figure 3From: Immunohistochemical study of the phenotypic change of the mesenchymal cells during portal tract maturation in normal and fibrous (ductal plate malformation) fetal liverAlpha-smooth muscle actin (ASMA) expression in normal fetal liver. At the remodelled stage, ASMA expression in portal tract is confined to the tunica media of vessels (20 WD) (V: portal vein; A: artery; B: bile duct).Back to article page
