Glioblastoma has one of the highest mortality rates among cancers, and it is the most common and malignant form of brain cancer. Among the typical features of glioblastoma tumors, there is an aberrant vascularization: all gliomas are among the most vascularized/angiogenic tumors. In recent years, it has become clear that glioblastoma cells can secrete extracellular vesicles which are spherical and membrane-enclosed particles released, in vitro or in vivo, by both normal and tumor cells; they are involved in the regulation of both physiological and pathological processes; among the latter, cancer is the most widely studied. Extracellular vesicles from tumor cells convey messages to other tumor cells, but also to normal stromal cells in order to create a microenvironment that supports cancer growth and progression and are implicated in drug resistance, escape from immunosurveillance and from apoptosis …
