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:Genetically matched human iPSCs from different origins were generated using bone marrow stromal cells and dermal fibroblasts of the same donor, and the global gene expression profile were analyzed. Comparison of gene expressions among 14 iPS clones, 4 and 4 were derived from bone marrow stromal cells(BM), 2 and 4 were from dermal skin fibroblasts(SF) of donor90 and 91, respectively.
Project description:The bone marrow microenvironment is a complex mixture of cells that function in concert to regulate hematopoiesis. Cellular components include fixed nonhematopoietic stromal elements (MSC) as well as monocytes and resident macrophages, which are derived from the hematopoietic stem cells. Clinical studies have shown healing effects, direct or indirect, from the injection of MSC int Keywords: Cell type comparison Canine bone marrow stromal cells were immortalized by transduction with a replication-defective recombinant retrovirus containing the human papilloma virus E6/E7 genes (pLXSN-16 E6E7), as described for human stromal cell lines in Roecklein and Torok-Storb (Blood 85:997-1005, 1995). Transduced clones were selected with 50 ug/ml G418 and resistant clones were isolated, grown to confluency and characterized for morphology, cytokine production and cell surface molecule expression. These cells are intended for clinical research in the canine transplantation model, as a complement for existing human stromal cell lines, for mitigation of graft-versus-host disease and radiation effects.
Project description:To describe the protein profile in hippocampus, colon and ileum tissue’ changing after the old faeces transplants, we adopted a quantitative label free proteomics approach.
