Caveolin-1 (Cav-1) is the main protein in caveolae, and serves as a scaffolding protein onto which many classes of signalling molecules are assembled. Through interaction with protooncogene products, Cav-1 may suppress cell proliferation; or when phosphorylated, may also stimulate cell growth. The aim of this study was to determine Cav-1 expression in human fetal tissues, tissues composed of cells undergoing growth and differentiation processes which require a nurturing environment provided by transmembrane vesicular transport. By using immunohistochemistry, Cav-1 was detected in several fetal tissues during mid- and late gestation (from 14 to 39 weeks). The protein was present in adipocytes, endothelial cells, smooth muscle fibers and in a number of sites with a pattern of distribution similar to that of the adult. Intriguingly, a positive immunoreaction for Cav-1 was also noticed in tissues, such as the urothelium, which normally do not express this protein in adulthood. This unexpected pattern of Cav-1 in human fetus may predict novel roles for Cav-1 during fetal development.

Abstract
Caveolin-1 (Cav-1) is the main protein in caveolae, and serves as a scaffolding protein onto which many classes of signalling molecules are assembled. Through interaction with protooncogene products, Cav-1 may suppress cell proliferation; or when phosphorylated, may also stimulate cell growth. The aim of this study was to determine Cav-1 expression in human fetal tissues, tissues composed of cells undergoing growth and differentiation processes which require a nurturing environment provided by transmembrane vesicular transport. By using immunohistochemistry, Cav-1 was detected in several fetal tissues during mid- and late gestation (from 14 to 39 weeks). The protein was present in adipocytes, endothelial cells, smooth muscle fibers and in a number of sites with a pattern of distribution similar to that of the adult. Intriguingly, a positive immunoreaction for Cav-1 was also noticed in tissues, such as the urothelium, which normally do not express this protein in adulthood. This unexpected pattern of Cav-1 in human fetus may predict novel roles for Cav-1 during fetal development.Pubblicazioni consigliate
