Project description:The recent interest in the role of bone marrow derived endothelial progenitor cells in the benefits of estrogen on cardiovascular health brought us to evaluate if estrogen could affect cardiac repair more broadly by regulating biological processes involved in the functional organization of the bone marrow stem cell niche. To assess such possibility, we evaluated gene expression profiles of bone marrow c-kit+ stem cells and CD44+ stromal cells, derived from primary whole bone marrow cultured system, after exposure to a physiological concentration of 17?-estradiol (17?E). Keywords: estrogen treatment response 6 samples per cell type (c-kit+ stem cells or CD44+ stromal cells) were analysed. Of these, triplicates of 17?E treated and corresponding control non-treated cells are included.

To assess such possibility, we evaluated gene expression profiles of bone marrow c-kit+ stem cells and CD44+ stromal cells, derived from primary whole bone marrow cultured system, after exposure to a physiological concentration of 17β-estradiol (17βE).

Project description:A transcriptome study in mouse hematopoietic stem cells was performed using a sensitive SAGE method, in an attempt to detect medium and low abundant transcripts expressed in these cells. Among a total of 31,380 unique transcript, 17,326 (55%) known genes were detected, 14,054 (45%) low-copy transcripts that have no matches to currently known genes. 3,899 (23%) were alternatively spliced transcripts of the known genes and 3,754 (22%) represent anti-sense transcripts from known genes. Mouse hematopoietic stem cells were purified from bone marrow cells using negative and positive selection with a Magnetic-Activated Cell Sorter (MACS). total RNA and mRNA were purified from the purified cells using Trizol reagent and magnetic oligo dT beads. Double strand cDNAs were synthesized using a cDNA synthesis kit and anchored oligo dT primers. After NlaIII digestion, 3’ cDNAs were isolated and amplified through 16-cycle PCR. SAGE tags were released from the 3’ cDNA after linker ligation. Ditags were formed, concatemerized and cloned into a pZERO vector. Sequencing reactions were performed with the ET sequencing terminator kit. Sequences were collected using a Megabase 1000 sequencer. SAGE tag sequences were extracted using SAGE 2000 software.
Project description:Subcutanesouly tumors from both Bmal1+/+ and Bmal1-/- mice were used to isolated stromal vascular fractions (SVF). Tumor cells with GFP+ signals were exclusive. Remain GFP- cells were collected to do RNAseq.

Project description:We used the resolving power of single-cell transcriptional profiling to molecularly characterize the mouse adipose stem and progenitor cell-enriched, subcutaneous adipose stromal vascular fraction. We molecularly assessed CD45- CD31- SVF cells using the 10x Genomics Chromium (10x) platform.
Project description:Genome wide expression profiling to determine the overlap of Affymetrix-signals with SOLID sequencing RNA was extracted using the Qiagen RNeasy kit following the manufacturers guidelines, arrays were prepared and hybridized following the Affymetrix protocol.
