Elucidating key aspects of zebrafish lymphocyte development and exploring the breadth of effector functions would provide valuable insight into the evolution of adaptive immunity. We performed single cell RNA sequencing on 70 000 cells from the zebrafish marrow and thymus to establish a gene expression map of zebrafish immune cell development. We uncovered rich cellular diversity in the juvenile and adult zebrafish thymus elucidated B and T cell developmental trajectories and transcriptionally characterized subsets of hematopoietic stem and progenitor cells and early thymic progenitors. Our analysis permitted the identification of two dendritic like cell populations and provided evidence in support of the existence of a pre B cell state. Our results provide critical insights into the landscape of zebrafish immunology and offer a foundation for cellular and genetic studies. Overall design: To analyze the composition of the zebrafish primary hematopoietic organs and to characterize immune cell subpopulations a total of 7 adult zebrafish 3 mpf 5 mpf and 21 juvenile zebrafish 4 wpf were studied. More specifically kidney marrows only were dissected from 3 adult GESTALT zebrafish paired kidney marrows and thymi were dissected from 2 adult GESTALT zebrafish and thymi only were dissected from 2 adult Tglck:eGFP zebrafish. Thymi only were dissected and pooled from 21 juvenile Tglck:eGFP zebrafish. No other pooling as performed. All tissues were subjected to mechanical dissociation filtering and cell sorting on a BD FACSAriaII. Live cells from whole thymi and two fractions of live cells from whole kidney marrow sorted based on FSC and SSC characteristics lymphoid and progenitor fraction; granulocyte fraction were collected in preparation for 10x single cell RNA sequencing. A single 10x lane was used for each adult sample whereas 4 lanes were used for the juvenile thymi to obtain 4 technical replicates.		pubmed:35938989		Juvenile Thymus 3	GSM5732081		tissue:sorted live thymus cells\|cell type:sorted live thymus cells\|strain:Tglck:eGFP\|developmental stage:Juvenile\|age:4 wpf bleed:no\|dissection buffer:0.5% BSA in HBSS no Ca2+ or Mg2+\|dissection temperature:room temperature	Juvenile Thymus 3	The libraries were sequenced on NovaSeq platforms. BCL files were analyzed with the Cell Ranger pipeline version 3.1.0. The demultiplexed FASTQ data was aligned to zebrafish Ensembl GRCz11 reference and generated the single cell count matrix.

Live cells were sorted 85 um nozzle on a BD FACSAriaII into 300 μL of 0.5% BSA in DPBS and kept on ice following the sort. Between 50 000 and 100 000 cells were sorted per sample assessed by Trypan blue staining and then pelleted by centrifugation at 400g x 5 minutes and resuspended to a final concentration of 1000 cells/uL. Transcriptome profiling was performed using the Chromium Next GEM Single Cell 3’ v3.1 Reagent Kits 10x Genomics Inc.. A targeted recovery of 6 000 cells was set for loading the Chromium Controller in all assays and steps were performed as described in the Chromium Next GEM Single Cell 3’ Reagent Kits v3.1 User Guide Rev D.
