PMID: 25101261
Front Chem. 2014 Jul 18;2:52. doi: 10.3389/fchem.2014.00052. eCollection 2014.

We developed a microfibrous poly(L-lactic acid) (PLLA) nerve conduit with a three-layered structure to simultaneously enhance nerve regeneration and prevent adhesion of surrounding tissue. The inner layer was composed of PLLA microfiber containing 25% elastin-laminin mimetic protein (AG73-(VPGIG)30) that...
