Figure 1From: 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 ductal plate stage, all fusiform cells in the portal stroma express ASMA (15 WD) (V: portal vein; D: ductal plate).Back to article page
