3D cultures of rat astrocytes and brain capillary endothelial cells on Poly-L-lactic acid scaffolds
2016
Tissue engineering is an emerging multidisciplinary field that aims at reproducing in vitro and/or in vivo tissues with morphological and functional features similar to the biological tissue of the human body. In this communication we report setting of three-dimensional structures able to mimic the extracellular matrix of the nervous system: we prepared Poly-L-Lactic Acid (PLLA) porous scaffolds via thermally induced phase separation (TIPS), and investigated the parameters that influence porosity, average pore size and degree of interconnection, i.e. polymer concentration, temperature and time of process. Astrocytes and brain capillary endothelial cells (BCECs) were cultured on these three-…
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…
