Project description:Purpose: The goal of this study was to establish the first detailed cell atlas of the regenerating caudal fin of zebrafish larvae. Intact and regenerating caudal fin were used for single-cell RNA-sequencing with the aim to provide the first integrated model of epimorphic regeneration in zebrafish larvae and demonstrate the diversity of the cells required for blastema formation. Methods: 150 of regenerating caudal fin (cut) and intact caudal fine (uncut) samples were dissociated and loaded into the 10x Genomics Chromium Platform, and sequenced using Illumina NovaSeq 6000. Conclusion: Our study constitutes a resource of the gene expression profile in intact and regenerating caudal fin of zebrafish larvae. We report the application of single-molecule-based sequencing technology for high-throughput profiling of both intact (uncut) and regenerating caudal fin samples (cut) at 24hpA. We confirmed the presence of macrophage subsets, previously described by our group to govern zebrafish fin regeneration, and identified a novel blastemal cell population.

Project description:Teleost fish have the remarkable ability to regenerate their body parts including heart, spinal cord, and the caudal fin, while many higher vertebrates including us humans have only a limited ability. To facilitate molecular and genetic approaches for regeneration, we previously established an assay using the fin fold of early stage larvae, which regenerate their caudal fin folds as in adult regeneration. Here, we performed transcriptional profiling of regenerating larval fin folds and identified genes with differential expression during regeneration. Gene expression profiling of zebrafish larval fin-fold regeneration was performed by comparing amputated fin fold and uncut control. Keywords: Stress response, injury response. Two time points, 18-24 hours post amputation (hpa) and 48 hpa, of regenerating fin fold were analyzed. We performed one replicate per each time point. For microarray expression profiling, total RNA was extracted from regenerating and uncut caudal fin folds of AB strain larvae. Tail tissues of 16-24 hpa, 48 hpa, and uncut siblings of the respective stages including 3-5 posterior somite segments were collected on ice. Total RNA was extracted by using TRIzol reagent (Invitrogen, Carlsbad, California, United States) according to the manufacturerâs instruction. The quantity and quality of total RNA were assessed by absorbance at 260 nm and 280 nm and by gel electrophoresis. Approx. 9 μg of total RNA was recovered from ~250 tail tissues at 16-24 hpa or uncut control tissues; and approx. 5 μg, from ~130 tail tissues at 48 hpa or uncut control tissues. Probes for microarray analysis were labeled with cy3 (amputated fin fold at 16-24 hpa and uncut control at 48 hpa) or cy5 (uncut control at 16-24 hpa and amputated fin fold at 48 hpa), and used for hybridization.

Project description:Adult zebrafish can completely regenerate their caudal fin following amputation. This complex process is initiated by the formation of an epithelial would cap over the amputation site by 12 hours post amputation (hpa). Once the cap is formed, mesenchymal cells proliferate and migrate from sites distal to the wound plane and accumulate under the epithelial cap forming the blastemal structure within 48 hpa. Blastemal cells proliferate and differentiate, replacing the amputated tissues, which are populated with angiogenic vessels and innervating nerves during the regenerative outgrowth phase which is completed around 14 days post amputation (dpa). Regenerative outgrowth does not occur in TCDD-exposed zebrafish. To identify the molecular pathways that are perturbed by TCDD exposure, male zebrafish were i.p. injected with 50 ng/g TCDD or vehicle and caudal fins were amputated. Regenerating fin tissue was collected at 1, 3 and 5 dpa for mRNA abundance analysis. Microarray analysis and quantitative real time PCR revealed that wound healing and regeneration alone altered the expression of nearly 900 genes by at least two fold between 1 and 5 dpa. TCDD altered the abundance of 370 genes at least two fold. Among these, several known aryl hydrocarbon responsive genes were identified in addition to several genes involved in extracellular matrix composition and metabolism. The profile of misexpressed genes is suggestive of impaired cellular differentiation and extracellular matrix composition potentially regulated by Sox9b. Experiment Overall Design: Regenerating fins were isolated at 1, 3 and 5 days post amputation. Three replicates were collected at each time point. 10 fins were pooled to comprise one replicate. Fish were dosed at 0 days post amputation with vehicle control alone or 50 ng/g TCDD.

Project description:Adult zebrafish are able to regenerate many organs such as their caudal fin in only few days post amputation. To explore the landscape and dynamic of the genes involed in regeneration, we performed a global transcriptomic analysis using RNA-seq during zebrafish caudal fin regeneration.

Project description:Previous studies of zebrafish caudal fin regeneration have shown that multiple genetic programs are moduled through regulatory factors. MicroRNAs are short highly conserved non-coding genes that suppress expression of target genes and thereby control multiple genetic programs. Given their important regulatory roles and evolutionary conservation, we hypothesize that microRNAs define a conserved genetic regulatory circuit important for appendage regeneration. We characterized microRNA expression during zebrafish caudal fin regeneration using small RNA sequencing. The stages of caudal fin regeneration were assayed for mRNA expression using mRNA sequencing. Small RNA and mRNA gene expression profiling during 0 and 4 days post amputation.
