Project description: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).

Proteomic profiling was performed of the lesion site at 1 dpl in control animals and animals with pdgfrb+ cell-specific overexpression of either zebrafish chondoradherin (chad; chad-mCherry fusion), fibromodulin a (fmoda; fmoda-mCherry fusion), lumican (lum; lum-mCherry fusion) or prolargin (prelp; prelp-mCherry fusion).

Project description:To analyse lesion-induced gene regulation in macrophage and microglia at single cell resolution, we performed single cell RNAseq on FACS-isolated mpeg1.1:GFP cells from the spinal cord at 24 hours post-lesion (hpl) after spinal injury at 3 days post-fertilisation (dpf), compared to age-matched uninjured animals.

Project description:The study was designed to identify genes regulated after spinal transection that might contribute to regenerative growth of neurons projecting from the NMLF in Zebrafish. Zebrafish were injured by surgical transection of the spinal cord at 1 mm caudal to the brainstem-spinal cord junction (Injured). Animals receiving sham surgery (identical surgical procedures without transection) served as control (Control). The nucleus of the medial longitudinal fascicle (NMLF) was laser capture microdissected from approximately 30 frozen sections. RNA was prepared, amplified, and run on Affymetrix Zebrafish arrays. Zebrafish were used because they recover swimming function after spinal transection in about 6 weeks. The NMLF has been identified as a prominent group of neurons that descend through the site of injury in the spinal cord and that regenerate after injury. Times were selected to distinguish early events from those in the timeframe of regenerative growth.

Project description:Adult zebrafish have the ability to recover from spinal cord injury and exhibit re-growth of descending axons from the brainstem to the spinal cord. We performed gene expression analysis using microarray to find damage-induced genes after spinal cord injury, which shows that Sox11b mRNA is up-regulated at 11 days after injury. However, the functional relevance of Sox11b for regeneration is not known. Here, we report that the up-regulation of Sox11b mRNA after spinal cord injury is mainly localized in ependymal cells lining the central canal and in newly differentiating neuronal precursors or immature neurons. Using an in vivo morpholino-based gene knockout approach, we demonstrate that Sox11b is essential for locomotor recovery after spinal cord injury. In the injured spinal cord, expression of the neural stem cell associated gene, Nestin, and the proneural gene Ascl1a (Mash1a), which are involved in the self-renewal and cell fate specification of endogenous neural stem cells, respectively, is regulated by Sox11b. Our data indicate that Sox11b promotes neuronal determination of endogenous stem cells and regenerative neurogenesis after spinal cord injury in the adult zebrafish. Enhancing Sox11b expression to promote proliferation and neurogenic determination of endogenous neural stem cells after injury may be a promising strategy in restorative therapy after spinal cord injury in mammals. Spinal cord injury or control sham injury was performed on adult zebrafish. After 4, 12, or 264 hrs, a 5 mm segment of spinal cord was dissected and processed (as a pool from 5 animals) in three replicate groups for each time point and treatment.
