Project description:To characterize early human hematopoiesis on a single-cell level we developed an approach termed index-omics, which combines flow-cytometric, single-cell transcriptomic and single-cell lineage fate data. Healthy human bone marrow was labeled with a panel of up to 11 FACS surface markers commonly used to identify human hematopoietic stem and progenitor cells (HSPCs). Lin-CD34+38+ progenitors and Lin-CD34+CD38- stem cell enriched HSPCs were individually sorted, their surface marker fluorescence intensities recorded, and subjected to single-cell RNAseq or single-cell ex vivo cultures.
Project description:In this study, we report a patient with a novel homozygous variant in HYOU1 (NM_001130991.3:c.1331C>A, p.Pro444His), who was born to related parents and presented with combined immunodeficiency, failure to thrive, and hypoglycemia. We undertook a multiomics analysis combining transcriptomics, proteomics, and single cell RNA sequencing analyses, demonstrating a drastic reduction in B cell count and hypogranulation of neutrophils in conformity with the findings of immunophenotyping. Additionally, we showed that despite the HYOU1 transcript being expressed and stable, the patient has HYOU1 deficiency at the protein level. Moreover, single cell RNA sequencing of bone marrow revealed that the B cell differentiation process is prematurely arrested at pre-pro B cell stage. The present dataset corresponds to the bulk RNAseq performed on bone marrow, human dermal fibroblasts (HDF) and PBMCs of the patient and healthy controls.

Moreover, single cell RNA sequencing of bone marrow revealed that the B cell differentiation process is prematurely arrested at pre-pro B cell stage. The present dataset corresponds to the single-cell RNAseq performed on unsorted cells obtained from peripheral blood and bone marrow samples of the patient and healthy controls (three biological replicates for the patient and four controls)
Project description:Single cell RNA-seq analyiss of FACS enriched OT-I CD8+ T cells following co-culture with SIINFEKL-pulsed bone marrow-derived DCs and bone marrow-derived myeloid-derived suppressor cells (T cell:DC:MDSC = 1:0.2:2)
Project description:Single-cell multiomics data collected from bone marrow mononuclear cells of 12 healthy human donors. Half the samples were measured using the 10X Multiome Gene Expression and Chromatin Accessability kit and half were measured using the 10X 3' Single-Cell Gene Expression kit with Feature Barcoding in combination with the BioLegend TotalSeq B Universal Human Panel v1.0. The dataset was generated to support Multimodal Single-Cell Data Integration Challenge at NeurIPS 2021. Samples were prepared using a standard protocol at four sites. The resulting data was then annotated to identify cell types and remove doublets. The dataset was designed with a nested batch layout such that some donor samples were measured at multiple sites with some donors measured at a single site. In the competition, participants were tasked with challenges including modality prediction, matching profiles from different modalities, and learning a joint embedding from multiple modalities.
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.
Project description:We have employed a single cell sequencing approach using 10x Genomics scRNAseq to study murine bone marrow contribution to cancer-induced bone pain. bone marrow are the mediator of sensory neurons and pain signaling. These findings establish a tumor-bearing reference dataset.
