Migration of brain capillary endothelial cells inside poly (lactic acid) 3D scaffolds

2017

The brain capillary endothelial cells (BCECs) form the blood brain barrier (BBB) under the effects of the brain microenvironment. BCECs are sealed together by tight junctions (TJs) that are responsible for the barrier phenotype. In these junctions, molecules such as JAM (junctional adhesion molecules), occludin and claudins are present. Threedimensional scaffolds are used to grow cells in order to obtain in vitro engineered tissues. On the base of these considerations, the aim of this work was to understand whether the endothelial cells were able to grow and survive on a new three-dimensional structure. If yes, indeed, this system could be further enriched and used to set a three-dimensiona…
