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:Proper control of inflammatory responses is essential for embryonic development, but the underlying mechanism is poorly understood. Here, we show that under physiological conditions, inactivation of ISG15, an inflammation amplifier, is associated with the interaction of Beclin 1 (Becn1), via its ECD domain, with STAT3 in the major fetal hematopoietic organ of mice. Conditional loss of Becn1 caused sequential dysfunction and exhaustion of fetal liver hematopoietic stem cells, leading to lethal inflammatory cell-biased hematopoiesis in the fetus. Molecularly, the absence of Becn1 resulted in the release of STAT3 from Becn1 tethering and subsequent phosphorylation and translocation to the nucleus, which in turn directly activated the transcription of ISG15 in fetal liver hematopoietic cells, coupled with increased ISGylation and production of inflammatory cytokines, whereas inactivating STAT3 reduced ISG15 transcription and inflammation but improved hematopoiesis potential, and further silencing ISG15 mitigated the above collapse in the Becn1 null hematopoietic lineage. The Becn1-STAT3-ISG15 axis remains functional in Atg5/7-disrupted fetal hematopoietic organs. These results suggest that Becn1, in an autophagy-independent manner, secures hematopoiesis and survival of the fetus by directly inhibiting STAT3-ISG15 activation to prevent cytokine storms. Our findings highlight a previously undocumented role of Becn1 in governing ISG15 to safeguard the fetus.

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.
