Characterization of PLGA based composite nerve guidance conduits: Effect of F127 content on modulus over time in simulated physiological conditions

PLGA/pluronic F127 based nerve guidance conduits (NGCs) for peripheral nerve regeneration offer excellent potential for clinical use. To date, little emphasis has been directed towards the effect of pluronic F127 on their subsequent mechanical properties as a function of degradation time or the physiological environment. This report was designed to redress the balance. This study synthesised 5 groups of 20 wt% PLGA NGCs with varied additions of pluronic F127 (range 0-5 wt%) to obtain Young's Moduli (E) in the range of 7-107 MPa, depending on degradation conditions and pluronic F127 content.
