Abstract:
:Abnormalities of the pulmonary vasculature are well documented in cases of congenital diaphragmatic hernia (CDH). Vascular endothelial growth factor (VEGF), an angiogenic factor, is a recently described endothelial cell-specific growth factor. Myosin heavy chain (MHC) isoforms such as SMemb, SM1 and SM2 are important molecular markers used to study vascular smooth muscle cell differentiation. SMemb is predominantly expressed in immature smooth muscle cells (SMC), and SM2 is expressed in mature SMCs. The authors investigated the expression of VEGF and SMC differentiation in pulmonary vessels in CDH rat lungs and in controls. The lungs of nitrofen-induced CDH rat fetuses (n = 16, gestational age 16, 18, 20, and 22 days) were stained immunohistochemically using antibodies against VEGF, SMemb and SM2, while alpha-actin was used as a general marker of vascular smooth muscle cells. In the CDH group VEGF expression was negative in pulmonary vessels before birth, and in the control group VEGF was positive in smooth muscle cells in vessel walls from 20 days both in vessels at the hilum and in pulmonary parenchyma. In both control and CDH groups, SMemb expression was positive from 16 days' gestation. SM2 expression was negative in vessel walls during the prenatal period in both groups. Alpha-actin was localized in both lungs obtained from control and CDH groups in the lung hilum from 16 days and around peripheral vessels from 18 days. Differences in vascular smooth muscle cell differentiation were not observed between control and CDH lung. These findings suggest that differences in pulmonary vascular development exist between control and CDH rats for VEGF expression, and maturational differences in smooth muscle cell differentiation are not present. This role of altered endothelial cell growth might be related to the different pulmonary vascular reactivity present in CDH lungs.
