Mechanical Ablation of Larval Zebrafish Spinal Cord.

Abstract

Unlike mammals, adult and larval zebrafish exhibit robust regeneration following traumatic spinal cord injury. This remarkable regenerative capacity, combined with exquisite imaging capabilities and an abundance of powerful genetic techniques, has established the zebrafish as an important vertebrate model for the study of neural regeneration. Here, we describe a protocol for the complete mechanical ablation of the larval zebrafish spinal cord. With practice, this protocol can be used to reproducibly injure upward of 100 samples per hour, facilitating the high-throughput screening of factors involved in spinal cord regeneration and repair.
