Project description:We performed cellular indexing of transcriptomes and epitopes by sequencing (CITE-seq) of the LSK compartment of TdT-reporter and TdT-fate mapping mice, in order to elucidate the heterogeneity and developmental trajectories within the MPP (lymphoid-primed multipotent progenitor) and HSC (hematopoietic stem cell) compartments.
Project description:We found that iron chelation restored functional defects in aged HSC, including engraftment potential and platelet bias. To gain molecular insights into iron-dependent mechanism for sustaining HSC identity during aging, we performed Cellular Indexing of Transcriptomes and Epitopes by Sequencing (CITE-seq) with lineage (Lin)− Sca-1+ cKit+ (LSK) cells isolated from aged mice after long-term regimens with iron chelator Deferoxamine or vehicle control.
Project description:Comparison of Mpl-/- mouse LSK cells, either treated with control (GFP) or Mpl lentivirus. Lineage negative bone marrow cells were isolated and transduced and transplanted into Mpl-/- recipient mice. After transplantation and follow up mice were sacrificed and LSK (lineage negative, Sca-1 positive, cKit positive) cells were isolated by FACS. RNA was isolated using RNeasy Micro Kit (Qiagen GmbH, Hilden, Germany) and RNA was amplified for microarray hybridization using the Nugen Ovation system (Nugen Technologies, AC Bemmel, Netherlands). The resulting material was hybridized to Affymetrix Mouse 430 2.0 arrays. RMA normalization and summarization was performed in R 2.10 using Bioconductor packages. The aim was to show the normalization of Mpl associated gene expression. 3 control (GFP transduced) samples of Mpl -/- mouse LSK cells and 3 treatment (Mpl transduced) samples of Mpl -/- mouse LSK cells.
Project description:We performed RNA sequencing analyses of adult mouse bone marrow lineage-negative, Sca-1-positive, and c-kit-positive (LSK) hematopoietic stem/progenitor cell population. Especially, we investigated gene expression profiling of LSK cells before and after haloperidol treatment.
Project description:To investigate heterogeneity of CD24 osteolineage cells at the single-cell level, we performed CITE-seq analysis with the CD24 antibody on bone and marrow mesenchymal cells from mouse femurs and tibias

Project description:We performed scRNA-seq and CITE-seq of CD45+ cells extracted from the steady state mouse heart, and at 5 days after myocardial infarction with or without depletion of CCR2+ cells
Project description:We found PAD4, which is one of the transcriptional co-regulator by histone modification, was highly expressed in lineage-, Sca-1+, c-kit+ (termed as LSK) cells of mouse bone marrow. To find the target genes which are regulated by PAD4 in LSK cells, we analyzed gene expression in PAD4-deficient mouse as compared with wild-type mouse.
