PDGFRβ and FGFR2 mediate endothelial cell differentiation capability of triple negative breast carcinoma cells

2014

Triple negative breast cancer (TNBC) is a very aggressive subgroup of breast carcinoma, still lacking specific markers for an effective targeted therapy and with a poorer prognosis compared to other breast cancer subtypes. In this study we investigated the possibility that TNBC cells contribute to the establishment of tumor vascular network by the process known as vasculogenic mimicry, through endothelial cell differentiation. Vascular-like functional properties of breast cancer cell lines were investigated in vitro by tube formation assay and in vivo by confocal microscopy, immunofluorescence or immunohistochemistry on frozen tumor sections. TNBCs express endothelial markers and acquire th…

Tumour vascularization via endothelial differentiation of glioblastoma stem-like cells

2010

Glioblastoma is a highly angiogenetic malignancy, the neoformed vessels of which are thought to arise by sprouting of pre-existing brain capillaries. The recent demonstration that a population of glioblastoma stem-like cells (GSCs) maintains glioblastomas indicates that the progeny of these cells may not be confined to the neural lineage. Normal neural stem cells are able to differentiate into functional endothelial cells. The connection between neural stem cells and the endothelial compartment seems to be critical in glioblastoma, where cancer stem cells closely interact with the vascular niche and promote angiogenesis through the release of vascular endothelial growth factor(VEGF) and str…

Structural Basis of Tumoral Angiogenesis

2003

Mammalian cells require oxygen and nutrients for metabolism and growth. In all cases tissues possess a vascular and lymphatic network assuring the supply of these needs within 200 to 250µm. Multicellular organisms that grow beyond this size require the recruitment of new blood vessels, although some normal tissues are devoid of specific vascularization (cartilage, cornea, epidermis), obtaining their oxygen and metabolic supply through perfusion
