Construction the larval and adult zebrafish cell atlas at single cell resolution

Project description:Single-cell mRNA sequencing (scRNA-seq) technologies are reshaping the current cell-type classification system. In previous studies, we built the mouse cell atlas (MCA) and human cell landscape (HCL) to catalog all cell types by collecting scRNA-seq data. However, systematically study for zebrafish (Danio rerio) and fruit fly (Drosophila melanogaster) are still lacking. Here, we construct the zebrafish and Drosophila cell atlas with Microwell-seq protocols, which provides valuable resources for characterization of diverse cell populations of zebrafish and Drosophila, and studying difference between vertebrates and Invertebrates at single cell level.

Single cell transcriptome atlas of the Drosophila larval brain

Single cell transcriptome atlas of the Drosophila larval brain

Project description:The cellular composition of the brain and how it is affected by starvation, remains largely unknown. Here we introduce a single-cell transcriptome atlas of the entire Drosophila melanogaster first instar larval brain. We first assigned cell type identity based on the expression of previously characterized marker genes, allowing us to distinguish five major groups: neural progenitors cells, differentiated neurons, glial cells, undifferentiated neurons as well as non-neural cells corresponding to organs and structures located adjacent to the brain. All major classes were further subdivided into multiple subtypes based on cluster analysis, revealing critical biological features of various cell types. Moreover, we included two different feeding conditions: normal fed versus starved. After starvation, the transcriptional profile of several cell clusters were altered, while the overall composition of the brain remains unaffected. Intriguingly, different cell clusters show very distinct responses to starvation, suggesting the presence of cell-specific programs for nutrition availability. Establishing a single-cell transcriptome atlas of the larval brain provides a powerful tool to explore cell diversity, assess genetic profiles of neurogenic, neuronal and glial cell types. The analysis of neurotransmitters, neuropeptides and their respective receptors may further open the doors for functional studies.

A scRNAseq atlas of larval Drosophila ventral cord - a resource for studying motor systems function and development

Project description:Drosophila larval ventral nerve cord (VNC) shares many similarities with the spinal cord of vertebrates and has emerged as a major model for understanding the development and function of motor systems. We use high quality single cell RNA sequencing to create a comprehensive atlas of larval VNC cell types. Our atlas provides a high-resolution characterization of larval VNC capturing primary neurons, glia and the functional landscape that coordinates larval behavior. At the same time, this atlas offers unique insights into neurogenesis and into the strategies and signaling networks utilized for generation of the adult VNC.

An atlas of neural crest lineages along the posterior developing zebrafish at single-cell resolution

Project description:Neural crest cells (NCCs) are vertebrate stem cells that give rise to various cell types throughout the developing body in early life. Here, we utilized single-cell transcriptomic analyses to delineate NCC-derivatives along the posterior developing vertebrate, zebrafish, during the late embryonic to early larval stage, a period when NCCs are actively differentiating into distinct cellular lineages. We identified several major NCC/NCC-derived cell-types including mesenchyme, neural crest, neural, neuronal, glial, and pigment, from which we resolved over three dozen cellular subtypes. We dissected gene expression signatures of pigment progenitors delineating into chromatophore lineages, mesenchyme subtypes, and enteric NCCs transforming into enteric neurons. Global analysis of NCC derivatives revealed they were demarcated by combinatorial hox gene codes, with distinct profiles within neuronal cells. From these analyses, we present a comprehensive cell-type atlas that can be utilized as a valuable resource for further mechanistic and evolutionary investigations of NCC differentiation.
