Abstract

The interaction of murine embryonic cortical neurons on randomly orientated electrospun scaffolds of poly(L-lactide) (P(L)LA) and poly(lactide-co-glycolide) (PLGA) is investigated in this study. The scaffolds were surface treated with different concentrations of KOH to partially hydrolyze the surface and therefore change the surface tension. Hydrophilicity did not significantly influence the number of primary and secondary branches; however, it had a considerable effect on neurite extension. For scaffolds with surface tensions of 40-47 dyn cm(-1) there was a significantly greater overall neurite length for both the primary and secondary branches compared with more hydrophilic scaffolds.
