Proteomics analysis of zebrafish spinal cord regeneration

Label-free mass spectrometry-based quantitative proteomics was applied to a larval zebrafish spinal cord injury model, which allows axon regeneration and functional recovery within two days (days post lesion; dpl) after a spinal cord transection in 3 day-old larvae (dpf). Proteomic profiling of the lesion site was performed at 1 dpl and 2 dpl as well as corresponding age-matched unlesioned control tissue (4 dpf as control for 1 dpl; 5 dpf as control for 2 dpl).
