Fig. 7From: Preparation of bilayer tissue-engineered polyurethane/poly-L-lactic acid nerve conduits and their in vitro characterization for use in peripheral nerve regenerationThe porosity of the PLA, PU, PU/MWCNT, and PLA/PU/MWCNT nanofibrous scaffolds. The PLA conduit to the PU, PU/MWCNT, and PLA/PU/MWCNT conduits, it was shown to have more porosity, but without statistical significance (P > 0.05). Data are presented as mean SD, n = 3Back to article page
