Project description:Among urochordates (tunicates)âthe closest living relatives of vertebratesâCiona intestinalis is increasingly being used as a model organism in the field of developmental biology. Ciona intestinalis is the seventh animal which genome published; the ~120-Mbp euchromatin region is estimated to contain ~16,000 protein-coding genes. In addition, analyses of more than one million ESTs have provided the foundation for gene models and associated transcriptomes. The fertilized Ciona intestinalis egg develops into a tadpole larva with a simplified chordate body plan, and then it metamorphose into adult sea squirt of sessile filter feeder. One of interests in the field of developmental biology is to understand what kind of genes are expressed in the body and how spatially and/or temporally coordinated expression of genes is controlled. In this study, we investigated the entire gene expression of 11 organs of adult Ciona; the neural complex, branchial sac, esophagus, stomach, endostyle, intestine, body-wall muscle, heart, blood cells, ovary, and testis. Our data would provides basic information of transcriptome in each organ and help to understand gene expression control of organ specific genes. Gene expressions in 11 organs of adult Ciona intestinalis; blood cells, branchial sac, digestive grand, endostyle, esophagus, heart, body-wall muscle, neural complex, ovary, stomach and testis. Three independent experiments were performed at each tissue using different individuals for each experiment.

Project description:The tadpole-type larva of Ciona has emerged as an intriguing model system for the study of neurodevelopment. The Ciona intestinalis connectome has been recently mapped, revealing the smallest central nervous system (CNS) known in any chordate, with only 177 neurons. This minimal CNS is highly reminiscent of larger CNS of vertebrates, sharing many conserved developmental processes, anatomical compartments, neuron subtypes, and even specific neural circuits. Thus, the Ciona tadpole offers a unique opportunity to understand the development and wiring of a chordate CNS at single-cell resolution. Here we report the use of single-cell RNAseq to profile the transcriptomes of single cells isolated by fluorescence-activated cell sorting (FACS) from the whole brain of Ciona robusta (formerly intestinalis Type A) larvae. We have also compared these profiles to bulk RNAseq data from specific subsets of brain cells isolated by FACS using cell type-specific reporter plasmid expression. Taken together, these datasets have begun to reveal the compartment- and cell-specific gene expression patterns that define the organization of the Ciona larval brain.

Project description:We report the comprehensive sequencing of small RNA libraries created from different developmental stages (larva and gastrula) of the basal chordate, Ciona intestinalis. These libraries were used for the identification of microRNAs in this organism. Sequencing of small RNA libraries from 2 stages of Ciona intestinalis.

Project description:We applied single cell RNA seq with 10x genomics platform to study the cell identity change in Ciona late tailbud embryos. By comparing single cell data from Pax3/7>Foxc amd control embryos, we found ectopic expression of FoxC in BTN cells transformed into PSC cells, which suggest common shared origin of BTNs and PSCs.

Project description:Ciona develops according to a stereotyped or invariant lineage. This allowed us to collect precisely defined replicates of all eight blastomeres of the right half of the embryo at the 16-cell stage of Ciona. We manually dissected each embryo, collecting and identifying each cell before library preparation and single-cell RNA-seq to give us a data set of 8 blastomeres x 4 embryos (32 cells). We sequenced these on MiSeq and HiSeq 2500. A fifth embryo was only sequenced on MiSeq and excluded from subsequent analysis.

Project description:Ciona intestinalis is an invertebrate animal model system that is well characterized and has many advantages for the study of cardiovascular biology. The regulatory mechanisms of cardiac myocyte proliferation in Ciona are intriguing since Ciona are capable of regeneration throughout their lifespan. To identify important regeneration factors in Ciona, microarray analysis was conducted on RNA from adult Ciona hearts with normal or damaged myocardium using custom Affymetrix GeneChips. After a 24- or 48-hour recovery period, total RNA was isolated from damaged and control hearts. Initial results indicate significant changes in gene expression in hearts damaged by ligation in comparison to cryoinjured or control hearts. Ligation injury shows differential expression of 223 genes as compared to control (fold change >2, p<0.01, Student’s t-test) with limited false discovery (5.8%). Among these 223 genes, 117 have known human orthologs of which 68 were up-regulated and 49 were down-regulated. Notably, FGF 9/16/20 and Ras were significantly upregulated in injured hearts. Histological analyses of injured myocardium were conducted in parallel to the microarray study. Taken together, these studies will coordinate differences in gene expression to cellular changes in the regenerative myocardium of Ciona, which will help to elucidate the regulatory mechanisms of cardiac myocyte proliferation across chordates.
