Project description:The goal of this study is to find skate pectoral fin motor neuron markers. Total RNA was extracted from manually sorted pectoral fin MNs, which were retrogradely labeled and tail spinal cord cells. By comparing RNA expression profiles of pectoral fin MNs and tail spinal cord neurons, we could identity general MN, MN columnar, and subset MN pool markers for fin MNs.

Project description:To identify gender specific differences in gene expression during fin rgeneration, pectoral fins were amputated from both male and female adult fish. Fins were allowed to recover for 4 days in standard tank condtions then tissue was collected for RNA isolation and microarray analysis Pooled samples from male and females, injured and uninjured in biological trilicate.

Project description:Previous studies of vertebrate appendage 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 Polypterus senegalus (bichir) pectoral fin regeneration using small RNA sequencing. The same samples were assayed for mRNA expression using mRNA sequencing. Small RNA and mRNA gene expression profiling during 0, 3, 7 and 14 days post amputation.

Project description:This study investigated the cell composition and lineage relationships of FACS (fluorescence activated cell sorting)-enriched epidermal, bone forming (osteoblast) and (non-osteoblast) blastemal fin regenerate cells by single cell (sc) RNA sequencing. The repetitive cell harvesting in four-week intervals revealed a constant gene regulation over four successive regeneration rounds in the early outgrowth stage. In addition, the sc RNA dataset uncovered a potential lineage relationship between distal blastema cells and osteoblasts during fin regeneration. These findings, together with the identification of novel fin regenerate markers, advance our understanding of complex tissue regeneration in zebrafish.

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.
