ScRNAseq for bone marrow cells from Cebpαcre/+ R26EYFP/+ SbdsF/F (neutropenia) mice vs Cebpαcre/+ R26EYFP/+ Sbds+/+ (Ctrl) mice

ABSTRACT: To delineate the potential molecular mechanisms underlying the communication between neutrophils and NK cells, we performed scRNAseq of the neutropenic bone marrow (12 months after transplantation of Cebpacre/+ Sbds +/+ or F/F cells). To this end, bone marrow cells were subsorted into HSC+MPP (LKS CD48-), HPC1 (LKS CD48+CD150-), B and T cells (B220+, CD3+), NK cells (NK1.1+ NKp46+) and a myeloid ‘rest’ fraction (B220-,CD3-,NKp46- and NK1.1-) and sorted fractions pooled together to obtain robust representation of all bone marrow cell types in the scRNAseq data

Gene expression level in normal HSCs (LKS+ cells) from different stages of AML

Project description:To investigate the molecular basis for the reversible suppression of HSCs by leukemia, we sorted the CD45.1+LKS+ population from control or leukemic mice at day 7 and day 14 for gene expression profiling analysis. CD45.1+LKS+ cells were sorted from leukemia and control groups at different time points. Microarray was performed at CapitalBio in Beijing. Total RNA was extracted using a Qiagen RNeasy Mini kit. We used the GeneChip Two-Cycle cDNA Synthesis Kit (Affymetrix) for cRNA amplification and labeling. RNA quality was confirmed using an Agilent 2100 bioanalyzer (Agilent Technologies). The amplified cRNA was labeled and hybridized to the Affymetrix Mouse Genome Array 430 2.0 (Affymetrix). Raw data were normalized using Microarray Analysis Software v5.0 (Affymetrix).

Bulk RNA sequencing of endothelial-derived and non-endothelial-derived BMSCs and OLCs of VE-Cadherin-Cre;LoxP-tdTomato mice

Project description:We performed lineage tracing experiments using VE-Cadherin-Cre;LoxP-tdTomato mice. In these mice, endothelial cells (ECs) and their progeny are permanently marked by tdTomato fluorescence. We found that a substantial subset of stromal cells is derived from ECs, as indicated by their tdTomato expression. These findings support the notion that endothelial to mesenchymal transition (EndoMT) contributes to hematopoietic bone marrow niche formation in mice. Here we sought to determine the transcriptomic differences between endothelial-derived (tdTomato-positive) and non-endothelial-derived (tdTomato-negative) bone marrow stromal cells (BMSCs) and osteo/chondrolineage progenitor cells (OLCs). Murine niche populations were obtained from collagenased bone fraction of VE-Cadherin-Cre;LoxP-tdTomato mice at 3 weeks (n=2) or 11 weeks (n=2) of age. BMSCs (CD45-TER119-CD31-CD144-SCA-1+ CD51+ cells) and OLCs (CD45-TER119-CD31-CD144-Sca1-CD51+ cells) were FACS-purified and sequenced.

B-myb is Essential Regulator of Hematopoietic Stem Cell and Myeloid Progenitor Cell Development

Project description:The B-myb (MYBL2) gene is a member of the MYB family of transcription factors and is involved in cell cycle regulation, DNA replication and maintenance of genomic integrity. However, its function during adult development and hematopoiesis is unknown. We show here that conditional inactivation of B-myb in vivo results in depletion of the HSC pool, leading to profound reductions in mature lymphoid, erythroid and myeloid cells. This defect is autonomous to the bone marrow and is first evident in the HSCs, which accumulate in the S and G2/M phases. B-myb inactivation also causes defects in the myeloid progenitor compartment and results in an accumulation of GMPs. Microarray studies indicate that B-myb null LKS+ cells differentially express genes that direct myeloid lineage development and commitment, suggesting that B-myb is a key player in controlling cell fate. Collectively, these studies demonstrate that B-myb is essential for HSC and progenitor maintenance and survival during hematopoiesis. Total RNA was isolated from FACS purified LKS+ cells isolated from pIpC-treated control and B-myb floxed-MxCre mice. Each sample is derived from a pool of 3-5 mice. 2 samples were analyzed for each genotype.

Single cell RNA-sequencing of murine endothelial and stromal populations at embryonic day 17 (E17)

Project description:The origin of bone marrow stromal cells (BMSCs) is not completely understood. We have identified a rare population of cells with a transcriptional profile consistent with endothelial to mesenchymal transition (Endo-MT) in human fetal development. Therefore, we hypothesized that Endo-MT contributes to bone marrow niche formation in mammals. Here, we sought to determine whether Endo-MT cells could be identified in murine bone marrow during embryonic development. We isolated bone marrow and collagenased bone fraction from long bones of 9 fetuses at embryonic day 17 (E17) and FACS purified endothelial cells and BMSCs for single cell RNA sequencing.

The Apcmin mouse has altered hematopoietic stem cell function and provides a model for MPD/MDS

Project description:Apc, a negative regulator of the canonical Wnt signaling pathway, is a bona-fide tumor suppressor whose loss of function results in intestinal polyposis. APC is located in a commonly deleted region on human chromosome 5q, associated with myelodysplastic syndrome (MDS) suggesting that haploinsufficiency of APC contributes to the MDS phenotype. Analysis of the hematopoietic system of mice with the Apcmin allele that results in a premature stop codon and loss of function, showed no abnormality in steady state hematopoiesis. Bone marrow derived from Apcmin mice showed enhanced repopulation potential, indicating of a cell intrinsic gain of function in the long-term hematopoietic stem cell (HSC) population. However, Apcmin bone marrow was unable to repopulate secondary recipients due to loss of the quiescent HSC population. Apcmin mice developed a myelodysplastic/ myeloproliferative phenotype. Our data indicate that Wnt activation through haploinsufficiency of Apc causes insidious loss of HSC function that is only evident in serial transplantation strategies. These data provide a cautionary note for HSC expansion strategies through Wnt pathway activation, provide evidence that cell extrinsic factors can contribute to the development of myeloid disease and indicate that loss of function of APC may contribute to the phenotype observed in patients with MDS and del(5q). LKS+ cells were isolated from Apcmin or WT mice using high-speed multiparameter flow cytometry. At least 2x104 cells per mouse were isolated with confirmed purity in excess of 90%. The cells were treated with RLT lysis buffer (Qiagen) containing beta-mercaptoethanol to stabilize RNA. RNA was extracted using Qiagen RNeasy Micro Kit according to manufacturers instruction. The RNA was amplified using a linear amplification protocol (Nugen Ovation V2 amplification system). cDNA was fragmented and biotinylated before hybridization onto Affymetrix mouse genome 430 2.0 Array chips

Physiological Jak2V617F expression causes a lethal myeloproliferative neoplasm with differential effects on hematopoietic stem and progenitor cells

Project description:We report a Jak2V617F knock-in mouse myeloproliferative neoplasm (MPN) model resembling human polycythemia vera (PV). The MPN is serially transplantable and we demonstrate that the hematopoietic stem cell (HSC) compartment has the unique capacity for disease initiation but does not have a selective competitive advantage over wild type HSCs. In contrast, myeloid progenitor populations are expanded and skewed towards the erythroid lineage, but cannot transplant the disease. Treatment with a JAK2 kinase inhibitor ameliorated the MPN phenotype, but did not eliminate the disease-initiating population. These findings provide insights into the consequences of JAK2 activation on HSC differentiation and function and have the potential to inform therapeutic approaches to JAK2V617F positive MPN. LKS cells were isolated from wild type (n=4) and JAK2V617F mutant mice (n=4). RNA was extracted using Qiagen RNeasy Micro Kit according to manufacturers instruction and amplified using NUGEN amplification kit. cDNA was fragmented and biotinylated before hybridization onto Affymetrix Mouse Expression Array 430 2.0.

Multi-tissue Single-Cell Analysis Deconstructs the Complexities of Mouse NK-ILC1 Programs

Project description:Natural killer (NK) cells and type 1 innate lymphoid cells (ILC1s) are a heterogenous group of T-bet+ innate cells that produce IFN-γ and are broadly defined as lineage–NK1.1+NKp46+ cells in mice. ILC1s definition primarily stems from studies on liver-resident and small intestinal populations. However, ILC1s in many anatomical sites, including visceral adipose tissue, salivary glands, and uterus, exhibit non-uniform programs that do not adequately overlap with those of liver or gut ILC1s or NK cells. Here, we performed single-cell RNA sequencing on murine NK1.1+NKp46+ cells from blood, spleen, lymph nodes, liver, salivary gland, uterus, visceral adipose tissue, small intestines, and several solid tumors. By including cells from an array of niches we defined tissue-specific ILC1 subsets. Moreover, we found a significant heterogeneity of circulating NK cells, due to a spectrum of proliferating, effector and migration programs, which was reduced in tumor-bearing mice, demonstrating repertoire reshaping in response to diseased conditions.
