In vivo haematopoietic cell production by bone marrow-derived hemogenic endothelium

ABSTRACT: By tracing the VE-cadherin expression in the newborn bone marrow hematopoietic LSK (lineage minus/Sca-positive/Kit-positive) cells, we demonstrated that the late foetal/newborn BM hemogenic endothelial cells produce a small cohort of hematopoietic stem and progenitor cells (HSPCs) capable of circulating and colonizing the secondary haematopoietic organs. Phenotypic and functional analyses disclosed that BM endothelium-derived HSPCs are mainly Multipotent Progenitors (MPPs) and a few Hematopoietic Stem Cells. We used microarrays to detail the global programme of gene expression underlying the endothelial origin of LSK cells in the newborn bone marrow.

Expression data from Bone marrow and Fetal liver Lineage-c-Kit+Sca-1+ (LSK) cells

Project description:Loss of polycomb-group gene Ezh2 causes activation of fetal gene signature in adult mouse bone marrow (BM) hematopoietic stem and progenitor cells (HSPCs). Ezh2 directly represses fetal-specific let-7 target genes, including Lin28, thereby cooperates with let-7 microRNAs in silencing fetal gene signature in BM HSPCs. We purified Lineage-Sca-1+c-Kit+ (LSK) HSPCs from E14.5 FL and adult BM and subjected them to microarray analysis.

The enzyme paraoxonase-2 modulates hematopoiesis through redox signaling

Project description:Long-term hematopoietic stem cells (LT-HSCs) reside in bone marrow (BM) niches with low levels of oxygen and reactive oxygen species (ROS). ROS enhancement results in differentiation of LT-HSCs. Redox disturbances are involved in BM failure and leukemia. Paraoxonase-2 (PON2) has been shown to be important for ROS control. However, the role of PON2 in the hematopoietic system has not been addressed. Analysis of young mice with inactivated Pon2 gene (Pon2-/- mice; 3 months) revealed changes in quantity of hematopoietic stem and progenitor cells (HSPCs), which indicate changes in cell differentiation. Experiments with aged PON2-/- mice (>9 months) showed alterations of the HSPC compartment indicating changed self-renewal ability of HSCs and myeloid skewing. Reciprocal BM transplantation reveals cell intrinsic as well as extrinsic phenotypes. We observed markedly enhanced superoxide levels in BM as well as slightly enhanced total ROS level in short term (ST)-HSCs and multipotent progenitor cells (MPPs) of young mice. In aged mice, total ROS level was slightly increased in all 3 fractions of the Lin-, Sca1+, ckit+ (LSK) population. No changes in the amount of DNA double-strand breaks in LSK cells and decreased apoptosis rates in LT-HSCs of young as well as LT- and ST-HSCs of aged PON2-/- mice were seen, indicating a strong compensation mechanism. Changes of gene expression in PON2-/- LT-HSCs identified by RNA sequencing strengthened our conclusions. Additionally, competitive and serial bone marrow transplantation experiments exposed advantages of PON2-/- BMCs in multi-lineage reconstitution. Collectively, these analyses propose PON2 as crucial redox control enzyme in HSCs.

The effect of periodontitis - induced trained immunity on the epigenomic profile of mouse bone marrow LSK and GMP cells

Project description:Peripheral inflammation affects hematopoietic stem and progenitor cells (HSPCs) in the bone marrow and induce myeloid lineage skewing of the progenitor cells. In this study, we performed single cell ATAC-sequencing in LSK (Lin—Sca-1+cKit+ ) and GMP (Lin—c-Kit+Sca1—CD16/32+CD34+) cells to determine the impact of ligature-induced periodontitis (LIP) on the epigenomic profile of these BM cells.

Project description:To better understand molecular phenotypes of Gabbr1 null mutant hematopoietic stem and progenitor cells (HSPCs), we sorted and pooled ~12,000 HSPCs (LSK population) from WT or Gabbr1 null P15 bone marrow for bulk RNA-seq analysis.

The effect of periodontitis - induced trained immunity on the transcriptomic profile of mouse LSK cells [RNA-seq]

Project description:Hematopoietic stem and progenitor cells (HSPCs) in the bone marrow can sense peripheral inflammation and adapt through expansion and skewing toward the myeloid lineage. In this study, we performed RNA sequencing in LSK (Lin—Sca-1+cKit+ ) cells to determine the impact of ligature-induced periodontitis on the transcriptomic profile of HSPCs in mice bone marrow.

Small Nucleolar RNAs in the Dlk1-Gtl2 Imprinting Locus Maintains LT-HSC Self-renewal by Regulation of rRNA Modification and Translation [ncRNA-Seq]

Project description:Small nucleolar RNA (snoRNA) are non-coding RNAs, which participate in the chemical modification of ribosomal RNAs (rRNAs) and small nuclear RNAs. However, the roles of snoRNA in homeostasis of hematopoietic stem cells(HSCs) have not been studied. We isolated four hematopoietic stem and progenitor cells (HSPCs) (LT-HSCs, IT-HSCs, ST-HSCs, and MPPs) from the bone marrow (BM) of C57BL/6 mice and performed small RNA-seq. We found SnoRNAs belonging to SNORD113-114 cluster were specifically enriched in LT-HSCs, and their expression decreased dramatically with HSC differentiation. Here, we used a modified small RNA-seq method to examine snoRNA profiles of hematopoietic progenitor and mature cells in WT mice.

RNA-seq profiling of HSC, MPPs and HPC-1s from Phf6-deleted and Phf6-intact mice

Project description:The study profiled the effect of Phf6 deletion on gene expression in hematopoietic stem cells (HSCs), multipotent progenitor cells (MPPs) and hematopoietic progenitor cells (HPC-1). Phf6lox/Y;Tie2-creTg/+ mice were prepared on a C57BL/6 background so that Phf6 deletion could be selectively mediated by Tie2-cre. Cell populations were sorted from bone marrow samples using standard surface markers (Lin–SCA1+cKIT+(LSK) CD150+ CD48– for HSCs, Lin–SCA1+cKIT+(LSK) CD150– CD48– for MPPs and Lin–SCA1+cKIT+(LSK) CD150- CD48+ for HPC-1 cells). Phf6 intact and Phf6-delected cells of all three types were profiled by paired-end RNA-seq using an Illumina NextSeq 500 sequencer. RNA-seq libraries were prepared from the HPC-1 samples used a standard Illumina TruSeq library protocol whereas the libraries for the HSC and MPP samples used a SMART-seq ultra low input kit for cDNA synthesis and amplification. Statistical analysis of the TruSeq and SMART-seq samples was undertaken separately.

Project description:Small nucleolar RNA (snoRNA) are non-coding RNAs, which participate in the cleavage and chemical modification of ribosomal RNAs (rRNAs) and small nuclear RNAs. However, the roles of snoRNA in homeostasis of hematopoietic stem cells(HSCs) have not been studied. We isolated four hematopoietic stem and progenitor cells (HSPCs) (LT-HSCs, IT-HSCs, ST-HSCs, and MPPs) from the bone marrow (BM) of C57BL/6 mice and performed small RNA-seq. We found SnoRNAs belonging to SNORD113-114 cluster were specifically enriched in LT-HSCs, and their expression decreased dramatically with HSC differentiation. To explore function of snoRNAs in SNORD113-114 cluster in HSCs, we established maternally KO mice by CRISPR-Cas9 technology. Here, we used RNA-seq to examine polysome RNA profiles in KO mice.
