To determine whether endothelial cells — the cells that line the interior surface of blood vessels — directly influence breast cancer cell growth, they then created unique organotypic models of lung and bone marrow microvascular niches, in which
endothelial cells formed blood vessel - like structures in culture as they would in the original organ.
Endothelial cells form the innermost layer of the blood vessels - the endothelium - and have the function of containing blood inside the vessels while allowing the passage of nutrients to tissues.
These malignant tumors were formed by poorly delineated vascular channels lined by pleomorphic
endothelial cells forming solid areas and with frequent mitotic figures.
