Schematic representation of implantation of the braided scaffolds into the injured spinal cord. Braided scaffolds were fabricated by interweaving eight PGA microfibres (10 µm in diameter) and have a hollow tubular structure (approximately 120–140 µm in diameter). Spinal cord injury (SCI) was made by bilateral transection of the dorsal spinal cord at the tenth thoracic level. Immediately after SCI, animals were implanted with two braided scaffolds (2 mm long) bridging the injured area (dorsal column). |
