Biología del Desarrollo Vascular: Mecanismos en Condiciones Físiológicas y Estrés Flujo

Abstract: RESUMEN: La vasculogénesis es controlada por una serie de mecanismos que se activan en función del tiempo y del espacio durante el desarrollo embrionario. Múltiples son las vías de señalización implicadas en las etapas del proceso vasculogénico, las que se inician con estímulos angiogénicos desde el mesodermo o desde el endodermo para dar origen a los angioblastos (células progenitoras endoteliales). Proteínas como el factor de crecimiento vascular endotelial (VEGF), factor de crecimiento fibroblastico 2 (FGF2… Show more

“…It is known that a mutation in the TEK gene in the VM lead to an alteration of the TIE2 receptor of angiopoietins 1,11,12 , which at the same time cause a pathological vasculogenesis and/or angiogenesis, modifying the relation between the venous endothelium and the pericytes 13 . This also explain why the venous malformation will grow at the same time the normal veins do.…”

“…Caveolin proteins (cav) take part in this structure and organization, being cav-1 the most important in vascular endothelium. In addition to cav-1, other proteins are present in these vesicles, such as tyrosine kinase receptor, G protein-coupled receptors, vascular endothelial growth factor (VEGF) receptor and calcium channels, which also participate in the mechanisms of mechano-transduction induced by FS 11 . The signalling pathways initiated from mechano-transduction converge in the activation and expression of the enzyme nitric oxide synthase (NOS).…”

“…Intussusception refers to the formation of pillars inside the blood vessel, resulting in its division into segments [ 2 ]. In the context of cancer, both vasculogenesis and angiogenesis are regulated by microenvironment-derived factors, tumor heterogeneity, cell–cell interactions (including malignant and non-transformed cells), as well as modifications on extracellular matrix (ECM) components [ 3 ]. In addition, there are alternative non-angiogenic mechanisms used by tumor cells to obtain nutrients and oxygen and to disseminate to distant sites, for instance vessel co-option, which consists in the hijacking of pre-existing blood vessels from non-tumoral surrounding tissue [ 4 ].…”
