Project description:The male germ cell differentiation is a subtle and complex regulation processes, currently its regulatory mechanism is not fully understood. In our experiment, we performed the first comprehensive genome wide analyses of the crucial genes in three kinds of crucial cells (ESCs, PGCs and SSCs) associated with the male germ cells differentiation. We identified thousands of differentially expressed genes (DEGs) in this process andwe choosed 173 candidate genes involved in the differentiation and metabolic processes, like GAL9, AMH, PLK1, PSMD7 and so on. Further exploration found that the candidate genes express patterns were the same between in vitro induction experiments and transcriptome results. Our results clues to the mechanistic basis of male germ cell differentiation and provides an important reference for future studies. Gene expression in chicken germ stem cells was measured at different stages of development. Three independent experiments were performed at each stage (ESCs, PGCs and SSCs).

Project description:We report the transcriptomes of 10 different chicken (Gallus gallus) cell/tissue types. The goal of this project was to determine similarities and differences between different cell/tissue types, with respect to protein coding genes, lncRNA, isoform counts, and differential gene expression. We provide raw data and bigWig files for UCSC visualization. The findings described here will be useful towards a complete annotation of chicken tissue and cellular transcriptomes.

Project description:A minor population of M cells within the follicle-associated epithelium (FAE) of intestinal Peyer’s patches (PP) serves as a major portal for entry of exogenous antigens. Characterization of the mammalian M cells, including identification of M-cell surface molecules used for bacterial uptake, has been hampered by their relative rarity. In contrast, M cells constitute virtually all of the FAE cells in the avian bursa of Fabricius. We therefore performed comparative gene expression profiling of chicken and murine FAE to identify commonly expressed genes by M cells in both species. The comprehensive transcriptome analysis revealed that 28 genes were commonly up-regulated in FAE from both species. In situ hybridization (ISH) revealed that annexin A10 (Anxa10) mRNA was scattered in FAE, and co-localized with Ulex europaeus agglutinin-1(UEA-1) that binds to M cells. Whole-mount immunostaining also revealed that cellular prion protein (PrPC) was expressed on the luminal side of the apical plasma membrane of M cells, and co-localized with grycoprotein2 (GP2) that recognizes only M cells in murine PP. Taken together, we found new M-cell-specific molecules by using comprehensive transcriptome analysis. These molecules conserved in M cells from both species might play critical roles in M-cell function and/or differentiation.

Project description:The existence of conventional dendritic cells (cDCs) has not yet been demonstrated outside mammals. In this paper, we identified bona fide cDCs in chicken spleen. Comparative profiling of global and of immune response gene expression, morphology, and T cell activation properties show that cDCs and macrophages (MPs) exist as distinct mononuclear phagocytes in chicken, resembling their human and mouse cell counterparts. Using computational analysis, core gene expression signatures for cDCs, MPs, T and B cells across chicken, human and mouse were established, which will facilitate the identification of these subsets in other vertebrates. Overall this study, by extending the newly uncovered cDC and MP paradigm to chicken, suggests that the generation of these two phagocyte lineages occurred before the reptile to mammal and bird transition in evolution. It opens avenues for the design of new vaccines and neutraceuticals that are mandatory for the sustained supply of poultry products in the expanding human population.

Project description:In poultry, in vitro derived primordial germ cells (PGCs) represent an important tool for management of genetic resources. However, several studies have highlighted sexual differences exhibited by PGCs through in vitro steps, which may compromise their reproductive capacities. To understand this phenomenon, we compared the proteome of pregonadal chicken male (ZZ) and female (ZW) PGCs expanded in vitro by quantitative proteomic analysis using a GeLC-MS/MS strategy. The proteins found to be differentially abundant in chicken male and female PGCs indicated their early sexual identity. Many of the proteins up-accumulated in male PGCs were encoded by genes strongly enriched in the sexual chromosome Z. This suggests that the known lack of dosage compensation of the transcription of Z-linked genes between sexes persists at protein level in PGCs, and that this may be a key factor of their autonomous sex differentiation. Male and female PGCs up-accumulated protein sets were associated with differential biological processes, and contained proteins biologically relevant for male and female germ cell development respectively. This study presents first evidence on early predetermined sex specific cell fate of chicken PGCs that will help to understand their sexual physiological specificities and enable more precise sex-specific adaptation of in vitro culture conditions.
