Description
Recent advances in single-cell transcriptomic profiling have provided unprecedented access to investigate cell heterogeneity during tissue and organ development. Here, we utilized massively parallel single-cell RNA sequencing to define cell heterogeneity within the zebrafish kidney marrow, constructing a comprehensive molecular atlas of definitive hematopoiesis and functionally-distinct renal cells found in adult zebrafish. Because our method analyzed blood and kidney cells in an unbiased manner, our approach was useful in characterizing immune cell deficiencies within prkdcD3612fs, il2rgaY91fs and double homozygous mutant fish, identifying blood cell losses in T, B, and natural killer cells within specific genetic mutants. Our analysis also uncovered novel cell types including two classes of natural killer immune cells, classically-defined and erythroid-primed hematopoietic stem and progenitor cells, mucin secreting kidney cells, and kidney stem/progenitor cells. In total, our work provides the first comprehensive single cell transcriptomic analysis of kidney and marrow cells in the adult zebrafish. Overall design: The goal of our study is to establish the transcriptional profiles of hematopoietic and kidney cell lineages residing in the zebrafish whole kidney marrow. Firstly, we performed single-cell RNA sequencing by a modified Smart-seq2 protocol on sorted single cells from fluorescent transgenic zebrafish lines, which label distinct blood cell types (n = 246 cells total). Secondly, we utilized droplet-based single-cell RNA sequencing (inDrop) to investigate unmarked, comprehensive hematopoietic lineage structure within wild-type, casper-strain zebrafish (N=3 animals, n=3,782 cells total). From this, we identified ten distinct hematopoietic groups of blood and immune identities. Thirdly, we confirmed blood lineage interpretations by comparing hematopoietic lineages within wild-type fish with mutant zebrafish with known immunodeficiencies, including prkdc(D3612fs) (N=3 animals, n=3,201 cells), il2rga(Y91fs) (N=2 animals, n=2,068 cells) and prkdc(D3612fs), il2rga(Y91fs) double compound mutant fish (N=2 animals, n=2,276 cells). Lastly, we identified seven structural and functional cell lineages of kidney identities in the whole kidney marrow (n=1,699 kidney cells).

Description
Purpose: We performed a time-course single-cell RNA-seq of the somatic cells of the XX mouse gonads to study the cell population heterogeneity and the genetic program during their differentiation. Methods: We collected gonads from NR5A1-eGFP transgenic embryos at six embryonic stages: E10.5, E11.5, E12.5, E13.5, E16.5 and P6. Methods: Cells were capture with the C1 autoprep system and cDNA sequenced with Illumina HiSeq 2000. Results: One cell population was detected at E10.5 and give rise to both Granulosa and steroidogenic precursor cells. A precursor cell population remains undifferentiated at P6 and are likely to be theca cell precursors. Conclusion: Our study is, to date, the most granular transcriptomic study of the developing mouse ovary and provide a more complete model of somatic cell differentiation during female sex determination. Overall design: 663 cells were collected in total. 71 cells at E10.5, 106 cells at E11.5, 164 cells at E12.5, 106 cells at E13.5, 95 cells at E16.5, and 121 at P6. We performed two independent captures for each embryonic stage to reach a reasonable number of cells except for E10.5 where we capture enough cells in one experiment.

Description
Our study revealed that hypoxia inducible factor 2 alpha, Hif2 alpha, is a downstream target of estrogen signaling in mouse uterine stroma at the time of implantation. Further, conditional deletion of Hif2 alpha in mouse uterus leads to infertility due to impaired epithelial remodeling at the time of implantation.

Description
The Arabidopsis thaliana transcription factor LATERAL ORGAN BOUNDARIES (LOB) is expressed in the boundary between the shoot apical meristem and initiating lateral organs. To identify genes regulated by LOB activity, we used an inducible 35S:LOB-GR line. This analysis identified genes that are differentially expressed in response to ectopic LOB activity.

We evaluated gene expression changes in murine leukemia caused by retroviral overexpression of MLL-AF9. We compared wild-type (WT) leukemia cells with mutant leukemia cells after cre-mediated inactivation of homozygous conditional alleles for Ezh2 or Eed, both of which are components of the Polycomb Repressive Complex2.

Description
The undifferentiated spermatogonial population of mouse testis is known to be functionally heterogeneous and contain both stem cells and committed progenitor cells. However, gene expression patterns marking these distinct cell fractions are poorly defined. We found that a subset of undifferentiated spermatogonia were marked by expression of a PDX1-GFP transgene but properties of these cells were unclear. Undifferentiated cells were therefore isolated from adult testes and separated according to expression of PDX1-GFP+ for gene expression analysis by RNA-seq. Our goal was to identify differentially expressed genes from PDX1-GFP+ vs PDX1-GFP- with that of known markers of stem and committed progenitor cells. Overall design: 4 independent sets of PDX1-GFP-positive and PDX1-GFP-negative undifferentiated spermatogonia were isolated by flow sorting from adult mouse testes.
