Project description:To determine how aging impacts gene expression in hematopoietic stem cells (HSCs), human CD34+ cells from bone marrow (34BM) and mobilized stem cell products (34P38NPBSC) were examined using microarray-based expression profiling. Differential expression changes were confirmed by microarray comparisons of younger and older expanded T-cell populations. Experiment Overall Design: We compared gene expression profiles between younger and older human CD34+ cells from bone marrow (34BM) and CD34+CD38- cells from mobilized stem cell products(34P38NPBSC). We also examined gene expression changes associated with aging in human expanded T-cells. For 34BM and T-cells, biotin-labeling of total RNA (5 µg) was performed as per standard Affymetrix protocol. For the 34P38NPBSC arrays, the single-stranded linear amplification protocol was used to process total RNA (100 nanograms) for the microarrays. Both protocols are described in detail in PMID14706461.

Project description:Mobilized-peripheral blood hematopoietic stem cells (HSCs) have been used for transplantation, immunotherapy, and cardiovascular regenerative medicine. Agents used for HPC mobilization include G-CSF and the CXCR4 inhibitor AMD3100. The HSCs cells mobilized by each agent may contain different subtypes and have different functions. To characterize mobilized HSCs used for clinical applications, microRNA (miRNA) profiling and gene expression profiling were used to compare AMD3100-mobilized CD133+ cells from 4 subjects, AMD3100 plus G-CSF-mobilized CD133+ cells from 4 subjects and G-CSF-mobilized CD34+ cells from 5 subjects. The HSCs were compared to peripheral blood leukocytes (PBLs) from 7 subjects.

Project description:A variety of somatic cells can be reprogrammed to induced pluripotent stem cells (iPSCs), but the small number of CD34+ hematopoietic stem cells (HSCs) present in non-mobilized peripheral blood (PB) would be a convenient and desirable starting target. We report here a simple method for targeting derivation of iPSC from non-mobilized PB CD34+ HSCs using immunobead purification and 2-4 day culture to achieve enrichment of CD34+ HSCs to 80±9%, followed by reprogramming transduction with loxP-flanked polycistronic (Oct4, Klf4, Sox2, and c-Myc) STEMCCA-loxP lentivector at an MOI of 2. Our yield was 4.7±2.2 iPSC colonies (n=12) per 20 mL non-mobilized peripheral blood, where most colonies had single copy STEMCCA-loxP that was easily excised by transient transfection expression of Cre. Resultant iPSC clones expressed pluripotent cell markers, had genomic methylation pattern closely matching embryonic stem cells, and generated teratomas containing tissues of all three germ lineages in immunodeficient mice. Furthermore, we conclude that these iPSC are derived from the non-mobilized CD34+ HSCs enriched from PB rather than from any lymphocyte or monocyte contaminants because they lacked somatic rearrangements typical of T or B lymphocytes, and because we demonstrated that purified CD14+ monocytes do not yield iPSC colonies under these reprogramming conditions.
