Aligned electrospun PLLA fiber scaffolds implanted into complete transection model of SCI in adult rats promote axonal regeneration across lesion site. A, D, G) PLLA films implanted into SCI transection lesion did not allow for axonal extension into lesion site over the course of 4 weeks. B, E, H) Random fiber conduits promoted marginal axonal extension, but significantly less than aligned fiber conduits in C, F, and I. 4 weeks after implantation of aligned fiber conduits, all animals exhibited axonal regeneration from the rostral spinal cord of at least 1.5 mm.
