Project description:Local renin antiotensin systems have been identified for many extra-renal sites. Bone marrow has been proposed as one such site, although the nature of the renin-expressing cell type(s) has not been established. Affymetrix microarrays were used to characterize the expression profile of renin-expressing GFP positive cells. Green fluorescent protein positive cells were sorted from whole bone marrow collected from adult transgenic mice. Bone marrow from several mice was collected and pooled on the day of a FACS sort. A portion of this was reserved for RNA extraction while the remainder was sorted. RNA was prepared with Trizol. Bone marrow collection and sorting was performed 3 times so that microarrays could be run in triplicate.

The model of bone marrow hematopoietic cells metabolism is derived from the community-driven global reconstruction of human metabolism (version 2.02, MODEL1109130000
).
This model is described in the article:
A community-driven global reconstruction of human metabolism.

Abstract:
Multiple models of human metabolism have been reconstructed, but each represents only a subset of our knowledge. Here we describe Recon 2, a community-driven,
consensus 'metabolic reconstruction', which is the most comprehensive representation of human metabolism that is applicable to computational modeling. Compared
with its predecessors, the reconstruction has improved topological and functional features, including ~2x more reactions and ~1.7x more unique metabolites. Using
Recon 2 we predicted changes in metabolite biomarkers for 49 inborn errors of metabolism with 77% accuracy when compared to experimental data. Mapping metabolomic
data and drug information onto Recon 2 demonstrates its potential for integrating and analyzing diverse data types. Using protein expression data, we automatically
generated a compendium of 65 cell type-specific models, providing a basis for manual curation or investigation of cell-specific metabolic properties. Recon 2 will
facilitate many future biomedical studies and is freely available at http://humanmetabolism.org/.

Project description:We have identified a population of adipocytes in fat tissue that arise from bone marrow-derived progenitor cells. We used microarrays to compare the global gene expression patterns of the bone marrow progenitor-derived adipocytes as well as conventional white and brown adipocytes to evaluate the relationship between these adipocyte subpopulations. Gonadal fat tissue (for white adipocytes) and intrascapular fat tissue (for brown adipocytes) was digested with collagenase and adipocytes were recovered by centrifugation/flotation. Bone marrow derived adipocytes were isolated from the adipocyte fraction of gonadal fat tissue from mice receiving bone marrow tranplants from donors expressing either green fluorescent protein (GFP) or beta-galactosidase (LacZ) by flow cytometry.
Project description:Purpose: The goals of this study are to compare the transcriptome profile of mouse hematopoietic stem/progenitor cells (HSPC) from the bone marrow overexpressing the innate immune adaptor protein TIRAP to control vector expressing HSPC using RNA-Seq. Methods: mRNA profiles of wild-type (WT) mice bone marrow overexpressing TIRAP or control vectors were generated by deep sequencing, in triplicate, using the Illumina platform. RNA-Seq data were aligned using JAGuaR (v2.0.3), using the mm10 reference. Expression quantification was performed with Sailfish (v0.6.2), using RefSeq gene models. The differential expression analysis between TIRAP expressing bone marrow and control was performed using DESeq2 (v1.10.1). Results: Using an optimized data analysis workflow, we mapped approximately 92% sequenced reads on average per sample to the mouse genome (build mm10).
Project description:Mass spectrometry results from TurboID experiments using constructs expressing TurboID only, NPM1wt-Turbo ID (N- and C-terminal fusions) and NPMc-Turbo ID fusions (N- and C-terminal fusions) transduced in primary mouse hematopoietic stem/progenitor cells from lineage-depleted mouse bone marrow.
Project description:Using a stromal cell free system, we described the gene expression and two genome wide epigenetic profiles of a unique population of undifferentiated bone marrow cells selectively driven towards the T cell differentiation pathway Undifferentiated bone marrow cells, transduced with NUP98-HOXB4 fusion protein, in vitro expanded with IL6 and SCF represents the hematopoietic stem cells (HSC); when grown in the presence of DLL4 (Notch1 ligand) and IL7, they are directed towards the T cell lineage (ProT); these in vitro generated ProT cells injected in a Rag2-/- mouse give rise to mature double positive T cells (DP). 2 replica for each population
