ERG promotes the maintenance of hematopoietic stem cells by restricting their differentiation

ABSTRACT: To investigate the role of the transcription factor ERG in hematopoiesis we generated Erg heterozygous knockout and conditional Erg knockout mice. We found that several hematopoietic cell types were decreased in these mice. To define Erg downstream target genes in hematopoietic stem cells, we sorted Lineage-, Sca-1+, c-kit+, CD150+, CD48- cells from Erg +/- mice for gene expression analysis. To define Erg downstream target genes in hematopoietic progenitors, we sorted multipotent progenitors (Lineage-, Sca-1+, c-kit+, CD150-) from Erg -/- mice for gene expression analysis.

We generated Erg heterozygous knockout mice and provide 3 replicates for wild type (Erg +/+) populations of stem cells (HSC) and 3 replicates for Erg +/- mices. We also generated a conditional Erg knockout mice. We provide 3 replicates for Erg fl/fl and 3 replicates for Erg (-/-) mice.

Fate mapping reveals two pathways of native thrombopoiesis (bulk RNA sequencing)

Project description:Bulk transcriptomes of Megakaryocyte progenitor cells isolated from bone marrow of WT mice; the following cell types were sorted: CD48high Megakaryocyte Progenitor (MkP): lineage- Sca-1- c-kit+ CD41+ CD150+ CD48hi; CD48-/low Megakaryocyte Progenitor (MkP): lineage- Sca-1- c-kit+ CD41+ CD150+ CD48lo

Gene expression data of Lsd1fl/fl and Lsd1fl/fl Mx1Cre CD150+ CD48- lin- c-Kit+ Sca-1+ LT-HSCs

Project description:We discovered that mice that lack Lsd1 in hematopoietic cells were exhibited increased frequencies of CD150+ CD48- lin- c-Kit+ Sca-1+ LT-HSCs, but completely lacked the lin- c-Kit+ Sca-1- myeloid progenitor compartment. To determine the genes altered by Lsd1-loss, CD150+ CD48- lin- c-Kit+ Sca-1+ LT-HSCs from Lsd1fl/fl and Lsd1fl/fl Mx1Cre mice were FACS-purified to be analyzed by gene expression profiling.

Gene expression signatures in Ythdf3-/- and WT hematopoietic stem cells

Project description:Analysis of Ythdf3-/- and WT hematopoietic stem cell (lineage-, c-kit+ Sca-1+ CD150+, CD34-). The hematopoietic stem cell (HSC) were purified from the bone marrow of WT and Ythdf3-/- mice.

Gene expression profiles of Jam2+ and Jam2- hematopoietic stem cells

Project description:Hematopoietic stem cells (HSCs: CD150+ CD48- c-kit+ Sca-I+ Lineage- cells) with or without cell surface expression of Jam2 were freshly sorted from C57BL/6 SJL mice. Total RNA was isolated from both, Jam2+ and Jam2- HSCs, using RNeasy Micro Kit (Qiagen) in accordance with the manufacturer's protocol. After the quality/quantity determination, RNA was subjected to expression analyses using Affymetrix GeneChip® Array / Mouse Gene 2.0 ST type.

scRNA-seq of mouse hematopoietic stem cells after 4 hours of LPS/PBS treatment in vivo.

Project description:To understand whether hematopoietic stem cells (HSCs) take part in emergency granulopoiesis, WT C57BL6 mice were treated intraperitoneally with 35 ug of LPS (lipopolysacharide) to induce emergency granulopoiesis or PBS control. Mice were sacrificed 4 hours after the treatment andHSCs (Lin-c-Kit+Sca-1+CD48-CD150+) were sorted and subjected to scRNA-seq.
