Hdac3 is essential for DNA replication and differentiation of hematopoietic stem and progenitor cells

Project description:Background: To define changes in gene expression from stem cells and early progenitor cells lacking histone deacetylase 3 (Hdac3), we purified bone marrow Lineage Negative, Sca1/cKit positive and Flt3 negative cells from wild type and Vav-Cre/Hdac3Flox/- mice. These lineage-specific knock out mice lack Hdac3 throughout the hematopoietic system. To ensure that only cells lacking Hdac3 were measured, we used a Lox-STOP-Lox-ROSA26-GFP transgene such that any cell containing active Cre also expresses GFP. Methods: Bone marrow cells were harvested from 10-30 mice and the lineage negative fraction was separated using the Lineage Cell Depletion Kit and MACS columns (Miltenyi Biotec). The lineage negative fraction was then stained with antibodies for flow cytometry and the GFP positive fraction of the LSK/Flt3 cells were sorted on a Becton Dickinson FACSAria. Total RNA was isolated from the sorted bone marrow cells using a PerfectPure RNA extraction kit (5 Prime). LSK/Flt3- cells pooled from 2 groups of 5 null mice were compared to LSK/Flt3- or LSK/Flt3+ cells pooled from 30 wild type mice. The expression of individual genes was verified using reverse transcriptase (RT) PCR. Conclusion: Hematopoietic stem and early progenitor cells fail to express gene that are typically turned on early during lymphoid development.

RNA-seq study on mouse bone marrow HSPC cells isolated from Arid2 conditional knockout and control mice.

Project description:We isolated lineage negative, cKit+, Sca1+ hematopoietic stem and progenitor cells from mouse bone marrow from Arid2fl/fl:MxCre+ (knockout) and MxCre+ (control) mice. Mice were injected with pIpC 6 weeks prior to isolation of LSK cells. Total RNA was isolated followed by mRNA selection. cDNA libraries were generated and NextGen Sequencing was performed.

Expression data of Hematopoietic progenitor and stem cells after 18h of culture with or without extracellular vesicles secreted by AFT stromal cells

Project description:Hematopoietic progenitor and stem cells from bone marrow have been sorted by FACS (LSK, Lineage -, Sca1 + and cKit +) and co-culture during 18h without cytokines with or without extracellular vesicles (EV) secreted by AFT stromal cells. We used microarray to detail the modification of gene expression level of LSK cells after contact with AFT Evs

Next Generation Sequencing of p53 KO and Utx/p53 DKO Hematopoietic Stem Cells Transcriptomes

Project description:Hematopoitic stem cells from Utx/p53 DKO mice showed increased self-renewal potential and predisposition of differentiation to myeloid lineage compared with those from p53 KO mice. To figure out what mechanism leads to the increased self-renewal, we compared the transcriptional profiles using RNA-sequencing of FACS sorted LSK (Lin-Ckit+Sca1+) cells, which contains the hematopoietic stem cells.

scRNA-Seq analysis of lineage negative compartments of miR-221/222-proficient and deficient mice.

Project description:To study the effect of miR-221/222-deficiency on early hematopoietic lineage differentiation pathways on sorted multipotent progenitor (MPP), common lymphoid progenitor (CLP), lineage-ckit+Sca1- and lineage-ckit-Sca1- populations of miRNA-proficient and deficient 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.

Single cell RNA Seq to study the effects of Palbociclib in the mouse LSK cell compartment

Project description:To understand how Palbociclib (a CDK4/6 inhibitor) treatment changes the transcriptome of hematopoietic stem and progenitor cells, wildtype cells were isolated from mice and treated for 24h with either PBS (control) or Palbociclib. After 24h of culture, the cell suspensions were collected and sorted for lineage-negative, Sca1-positive, cKit-positive (LSK) cells which were subjected to library prep for single cell RNA sequencing.

Gene expression changes during hematopoietic cell differentiation

Project description:Gene expression analyses of hematopoietic stem cells (HSCs), progenitor cells (HPCs), and differentiated cell. Gene expressions of long-term HSCs (CD34-ckit+Sca1+Lineage-), short term HSCs (CD34+ckit+Sca1+Lineage-), Progenitor cells (ckit+Sca1- Lineage-), and differentiated cels (Lineage+) were examined by microarray. Results provide insight into the mechanism of hematopoietic cell differentiation. Long-term HSCs (CD34-ckit+Sca1+Lineage-), Short term-HSCs (CD34+ckit+Sca1+Lineage-), Progenitor cells (ckit+Sca1- Lineage-, and Lineage+), and differentiated cell (Lineage+) were sorted from mouse bone marraw and were examined by microarray. Results provide insight into the mechanism of hematopoietic cell differentiation.
