Pericytes stabilize vessel wall, participate in the regulation of blood flow microcirculation and influence endothelial proliferation, survival, migration and maturation. Pericytes are commonly identified by molecular markers, such as desmin. The aim of this study was to analyze the pattern of distribution of desmin in the chick embryo chorioallantoic(More)
In Duchenne muscular dystrophy (DMD) metabolic and structural alterations of the central nervous system are described. Here, we investigated in the brain of 10 mdx mice and in five control ones, the expression of hypoxia inducible factor-1alpha (HIF-1alpha) and we correlated it with the expression of vascular endothelial growth factor (VEGF) and vascular(More)
In this study, for the first time, we investigated about the localization of VEGF-A, VEGFR-2 and Ang-2 in the choroid plexuses of the adult mouse by Western blot and immunohistochemistry. Results showed that VEGF-A stained epithelial cells, while anti-VEGFR-2 and -Ang-2 antibodies stained endothelial cells. These data suggest that Ang-2, converting blood(More)
Mast cells (MC) have been implicated in both normal and pathological angiogenesis, such as that in chronic inflammatory diseases and tumors. This assumption is partially supported by the close structural association between MC and blood vessels and the recruitment of these cells during tumor growth. MC release a number of angiogenic factors among which(More)
We have attempted a fine characterization of the angiogenic response induced by multiple myeloma endothelial cells (MMEC) by using the chick embryo chorioallantoic membrane (CAM) assay and by reverse transcriptase-polymerase chain reaction (RT-PCR). Results showed that in the CAM assay MMEC induced an angiogenic response comparable to that of a well-known(More)
The chick embryo chorioallantoic membrane (CAM) is commonly used in vivo to study both angiogenesis and anti-angiogenesis. Rapid membrane water transport is mediated by a family of molecular water channels, called aquaporins (AQPs), which have been identified in the epithelial and endothelial cells of higher vertebrates. AQP1, expressed in adsorptive and(More)
