Project description:Gene expression is highly dynamic during fetal development and determines tissue specification and function. In humans, the transcriptional profile of different organs during development has not been systematically studied. However, understanding how a particular tissue acquires its tissue identity will give insight into the development and maturation of tissues from a developmental biology perspective. Next-generation sequencing (DeepSAGE) dataset of 111 RNA samples representing 21 different human fetal organs and the maternal endometrium at three timepoints (gestational ages) during first and second trimester development (W9, W16-18, W22)

Project description:We profiled hematopoietic, lymphoid and peripheral fetal organs to systematically assess the heterogeneity of immune cell populations across human tissues during development. Single-cell suspensions were obtained from fresh tissue. Cells were either DAPI-CD45+ or DAPI-CD45- FACS-isolated cells, or unsorted.

Project description:Single-cell mRNA sequencing (mRNA-seq) technologies are reshaping the current cell-type classification system. In previous studies, we built a comprehensive mouse cell atlas to catalog all cell types by collecting scRNA-seq data in the fetal and adult stages. Howerver, systematically study for organism-level dynamic changes of cellular states across mouse life span are still lacking. Here, We made an updated version of mouse cell atlas (MCA) by adding scRNA-seq data covering 14 major mouse organs during different mouse development period. We revealed aging related regulatory networks and pathways that have not been well characterized previously. We found that the expressions of immune-related genes, such as antigen-presenting genes and immunoglobulin genes, appeared in non-immune cell types in aging process. We also focused on the expression of lung epithelial immunoglobulin genes and revealed their related transcriptional regulation mechanisms. The updated MCA resource provides a valuable resource for studying mammalian development, maturation and aging.

Project description:Adult endothelial cells (ECs) are known to possess organ-specific gene expression, morphology and function, but whether organ-specific EC gene expression is present during human development is not known. Here, we used bulk RNA-sequencing (RNA-seq) to interrogate the developing human intestine, lung, and kidney in order to identify organ-enriched EC-gene signatures. FACS was used to isolate EC (CD31+CD144+, n=13) and non-EC (CD31-CD144-, n=16) populations from these three organs, profiling at least 4 biological replicates for each organ system. The biological specimens profiled were between 11-20 gestational weeks. We also sequenced cultured human umbilical vein endothelial cells (HUVECs) via bulk RNAseq. Computational approaches were used to identify organ-specific EC-enriched gene signatures across human fetal lung, intestine, and kidney ECs.

Project description:Fetal and adult hematopoietic stem and progenitor cells (HSPCs) are characterized by distinct redox homeostasis that may influence their differential cellular behaviour in normal and malignant haematopoiesis. In this work, we have applied a quantitative mass spectrometry-based redox proteomic approach to comprehensively describe reversible cysteine modifications in primary mouse fetal and adult HSPCs. We defined the redox state of 4455 cysteines in fetal and adult HSPCs and demonstrated a higher susceptibility to oxidation of protein thiols in fetal HSPCs. Our data identified ontogenically active redox switches in proteins with a pronounced role in metabolism and protein homeostasis. Additional redox proteomic analysis identified redox switches acting in mitochondrial respiration as well as protein homeostasis to be triggered during onset of MLL-ENL leukemogenesis in fetal HSPCs. Our data has demonstrated that redox signalling contributes to the regulation of fundamental processes of developmental hematopoiesis and has pinpointed potential targetable redox-sensitive proteins in in utero-initiated MLL-rearranged leukaemia. An H9 human embryonic stem cells cell line was applied to validate data from the primary cells.

Project description:Due to its small and sequenced genome, short generation time, efficient transformation and increasing genetic resources, Brachypodium distachyon is an emerging model for grasses. Despite this, data capturing gene expression patterns across different organs and developmental stages is missing. We have generated a comprehensive gene expression atlas for Brachypodium, capturing 9 different organs and developmental stages
