Single-cell RNA sequencing of murine tumor-susceptible germ cells

ABSTRACT: In response to signals from the embryonic testis, germ cell intrinsic factor NANOS2 coordinates a sex-specific transcriptional program necessary for differentiation of pluripotent-like primordial germ cells toward a unipotent spermatogonial stem cell fate. Emerging evidence indicates that genetic risk factors contribute to testicular germ cell tumor initiation by disrupting sex-specific differentiation. Here, using a mouse model of spontaneous testicular teratomas, we report that a subpopulation of germ cells failing to express NANOS2 is enriched for developmental phenotypes required for tumorigenesis. We demonstrate that only in the absence of NANOS2 do germ cells have a transcriptional profile enriched for Myc signaling and primed pluripotency and transform into embryonal carcinoma cells. We conclude that NANOS2 is the nexus through which many genetic risk factors exert their influence on tumor susceptibility. We propose that NODAL signaling, which is present in the developing testis, drives germ cell transformation in the absence of sex specification.

Induction of Pluripotency in Adult Unipotent Germline Stem Cells

Project description:Mouse and human stem cells with features similar to those of embryonic stem cells have been derived from testicular cells. Although pluripotent stem cells have been obtained from defined germline stem cells (GSCs) of mouse neonatal testis, only multipotent stem cells have been obtained so far from defined cells of mouse adult testis. In this study we describe a robust and reproducible protocol for obtaining germline-derived pluripotent stem (gPS) cells from adult unipotent GSCs. Pluripotency of gPS cells was confirmed by in vitro and in vivo differentiation, including germ cell contribution and transmission. As determined by clonal analyses gPS cells indeed originate from unipotent GSCs. We propose that the conversion process requires a GSC culture microenvironment that depends on the initial number of plated GSCs and the length of culture time. Nine samples were analyzed. GSC1: Mouse Germ Stem Cells, line 1 (1 replicate), GSC2: Mouse Germ Stem Cells, line 2 (1 replicate), GSC3: Mouse Germ Stem Cells, line 3 (1 replicate), GSC4: Mouse Germ Stem Cells, line 4 (1 replicate) gPS1: Mouse clonal germ Pluripotent Stem cells, line 1, GFP-sorted (1 replicate), gPS2: Mouse clonal germ Pluripotent Stem cells, line 2, GFP-sorted (1 replicate), gPS3: Mouse clonal germ Pluripotent Stem cells, line 3, GFP-sorted (1 replicate) ESC: Mouse Embryonic Stem Cells (duplicate)

Gene expression of mouse embryonic gonad [Nanos2_Stra8]

Project description:To examine whether the meiosis was solo factor responsible for the disruption of the male gonocyte differenitiation in the Nanos2-/- male germ cells, we deleted Stra8 function from Nanos2-null background and performed expression microarray analysis of the Nanos2+/-/Stra8+/- , Nanos2-/-/Stra8+/-, and Nanos2-/-/Stra8-/- male emnbryonic gonads at E14.5. Biological duplicates were examined at each stage, genotype, and sex for each experiment.

Gene expression of mouse embryonic gonad

Project description:To elucidate the function of NANOS2 to regulate the transcriptome in embryonic male germ cells, we performed expression microarray analysis of the embyornic gonads of the Nanos2+/-, Nanos2-/- male and wild type female from E12.5 to E15.5. The Nanos2+/- and Nanos2-/- female gonads at E15.5 were analyzed as a negative control. Biological duplicates were examined at each stage, genotype, and sex for each experiment.

An RNA-interacting protein network regulates pluripotency in mammalian primordial germ cells (Dazl testis RNA-IP)

Project description:Primordial germ cells (PGCs) are the embryonic precursors to egg and sperm. When removed from the embryonic gonad, PGCs can give rise to embryonic germ cell lines (EGs), pluripotent stem cells that display most of the characteristics of embryonic stem cells (ESCs) including the ability to form teratomas and to contribute to chimera formation. In mice, EG cells can be derived between E8.5 up to E12.5 of embryonic development, at which point the PGCs undergo sexual differentiation and in the male transition into unipotent gonocytes. Dazl, a germ cell-specific RNA-binding protein, is specifically expressed in developing PGCs and is required for proper germ cell development. Dazl knockout mice are infertile, but the molecular mechanisms underlying this phenotype are still unknown. Here we demonstrate that Dazl localizes in granular structures in mammalian PGCs but not in ESCs. We demonstrate Dazl plays a central role in a large mRNA/protein interactive network that includes members of Fragile-X family RNA-binding proteins. We demonstrate that Dazl and Fxr1 play a central role in these granules and directly regulate the translation of specific core pluripotency factors, including Sox2 and Suz12. RNA species interacting specifically with Dazl in juvenile testicular germ cells were identified by RNA-IP microarray analysis. This dataset contains data from native RNA-IPs from P14 Dazl-GFP transgenic mouse testes. Native RNA-IP (anti-V5 and anti-PABP1) experiments from juvenile testicular germ cells expressing Dazl-GFP-V5. Input Total RNA and mock IP with normal mouse IgG were used as controls. Control and IP-enriched RNA samples were analyzed by Agilent Mouse Whole Genome 4X44K one-color microarrays. Two replicates for each condition were done.

aCGH from mouse gPAK testicular teratocarcinomas

Project description:Testicular germ cell tumors are among the most responsive solid cancers to conventional chemotherapy. To elucidate the underlying mechanisms, we developed a mouse testicular germ cell tumor model in which germ cell-specific oncogenic Kras activation and tumor suppressor Pten inactivation was driven by CRE-mediated recombination. The resulting mice rapidly developed malignant, metastatic testicular cancers composed of both teratoma and embryonal carcinoma, the latter of which exhibited stem cell characteristics, including expression of the pluripotency factor OCT4. As part of our analysis of mouse gPAK testicular tumors, as well as comparison to benign 129-Dnd1Ter/Ter testicular teratomas, we used NimbleGen Mouse CGH 3x720k Whole-Genome Tiling Arrays to assess copy number variations in this novel genetically engineered mouse model of malignant, metastatic testicular cancer.

Project description:Transcriptional profiling of E14.5 XY germ cells (marked with Oct4-EGFP transgene) from two strain backgrounds (C57BL/6J and 129S1/SvImJ) that differ in their susceptibility to testicular teratomas. Two condition experiment. For each sample, Oct4-EGFP+ germ cells from all XY embyos within a litter were pooled. For the C57BL/6J background, n=3 pooled biological replicates were profiled, and n=2 replicates were obtained and profiled for 129S1/SvImJ.
