PGA microfibres of braided scaffolds in the injured spinal cord were visible on X-ray phase-contrast CT with a synchrotron radiation source. High-magnification images of the X-ray phase-contrast CT (a) and histological section (b) in the sagittal plane 28 days after scaffold implantation into injured spinal cord. Arrowheads indicate PGA microfibres that were clearly visible using the X-ray phase-contrast imaging. Scale bar = 50 µm. |
