Three-dimensional imaging of the unsectioned adult spinal cord to assess axon regeneration and glial responses after injury

Abstract
Ali Erturk and colleagues present a novel tetrahydrofuran-based histological tissue clearing procedure that renders fixed and unsectioned adult CNS tissue (spinal cord and brainstem) transparent and, as such, fully amenable to a range of different optical imaging techniques. This three-dimensional imaging method can be used for studying axon regeneration and glial reactions.
