Project description:To investigate heterogeneity of senescence at the single-cell level, we performed scRNA-seq analysis on bone and marrow mesenchymal cells from aged mice
Project description:To study the effect of stress on macrophages due to Toxoplasma, we stimulated murine bone marrow-derived macrophages (BMDMs) with IFN-γ (no-stimulate control) and infected them with the apicomplexan parasite Toxoplasma gondii. scRNA-Seq (10X Chromium genomics ) was performed to understand the changes in the immune cells and study the impact of the parasite.
Project description:The malaria parasite Plasmodium replicates and differentiates in red blood cells of its host. The erythropoietic niches (spleen and bone marrow) are important but poorly understood reservoirs of asexual replication and sexual development. We aimed to understand how the parasite adapts to its host organ and a host cell level. For this, we performed single-cell RNA-seq (scRNA-seq) analysis on host and parasite cells derived from spleen, blood and bone marrow. Organs were harvested from two infected and one uninfected mice and parasite cells were enriched to about 50% by flow sorting (infected samples only). To identify host cells by surface expression (CITE-seq), cells were stained with barcoded antibodies targeting CD44 and CD71. Droplet-based scRNA-seq of these samples was performed using 10X genomics technology and cDNA was sequenced on Illumina.
Project description:We enriched endothelial cells and other bone marrow cells in both fetal and adult stage to investigate Wnt signaling interaction using targeted scRNA-seq analysis. This analysis facilitate identification of sources of Wnt ligands and detection of Wnt receptor expression in bone marrow. The comparison of fetal and adult stage reveals differences of Wnt signaling in fetal and adult BM.
Project description:Macrophages are cells of the innate immune system fundamental to support normal haematopoiesis, fight infection, anti-cancer immunity and tumour progression. However, the function of macrophages in myeloid leukaemias remain largely unknown, due to difficulties in isolating non-transformed cells from the malignant ones. Here we use a state-of-the-art chimeric mouse of chronic myeloid leukaemia (CML) to study in the impact of the dysregulated bone marrow (BM) microenvironment on bystander macrophages. Utilising single cell RNA sequencing (scRNA seq) of Philadelphia chromosome (Ph) negative macrophages and secretome proteomics of murine c-kit+ stem/progenitor cells we have uncovered that macrophages exposed to a CML environment are altered transcriptionally and have reduced phagocytic function
