Abstract
This work focuses on the evaluation of the potential use of electrospun poly(ε-caprolactone) (PCL) micrometric and/or sub-micrometric fibrous membranes for rat hippocampal astrocyte (HA) and rat cerebro-microvascular endothelial cell (CEC) cultures. Both mats supported cell adhesion, proliferation, cellular phenotype and spreading. Microfibrous mats allowed cellular infiltration, while both HAs and CECs were unable to migrate within the sub-micrometric fibrous mat, leaving an acellularized inner region. This finding was correlated to the presence of larger voids within electrospun PCL microfibrous mats, suggesting that the morphology should be accurately selected for the realization of a cell environment-mimicking mat. Based on our results, the proper fiber architecture can be regarded as a crucial issue to be considered in order to deal with suitable polymeric mats tailored for specific in vitro application.
