Direct generation of induced pluripotent stem cells from human non-mobilized blood

ABSTRACT: The use of induced pluripotent stem cells (iPSCs) is an exciting frontier in the study and treatment of human diseases through the generation of specific cell types. Here we show the derivation of iPSCs from human non-mobilized peripheral blood (PB) and bone marrow (BM) mononuclear cells (MNCs) by retroviral transduction of OCT3/4, SOX2, KLF4 and c-MYC. The PB- and BM-derived iPSCs were indistinguishable from human embryonic stem cells (hESCs) with respect to morphology, expression of surface antigens and pluripotency-associated transcription factors, global gene expression profiles and differentiation potential in vitro and in vivo. Infected PB and BM MNCs gave rise to iPSCs in the presence of several cytokines, although transduction efficiencies were not high. We found that 5×105 PB MNCs, which corresponds to less than 1 ml of PB, was enough for the generation of several iPSC colonies. Generation of iPSCs from MNCs of non-mobilized PB, with its relative efficiency and ease of harvesting, could enable the therapeutic use of patient-specific pluripotent stem cells.

Gene expression profiling of mobilized vs. Bone marrow (BM) resident hematopoietic stem and progenitor cells (LSK)

Project description:Expression prolile of CWHM-823+tGro-b mobilized (3 mg/kg + 2.5 mg/kg, s.c. injection, timepoint 30 min) HSPC was compared to that of AMD3100 (5 mg/kg, 1 hr after s.c. injection) or G-CSF (100 ug/kg/injection, q12h, 5 days) mobilized as well as BM resident HSPC. Accordingly, the cells were isolated from the BM of untreated or from the peripheral blood (PB) of differentially mobilized mice.

Characterization of transcriptomic changes induced by a gene therapy cell culture protocol to single human bone marrow and mobilized peripheral blood hematopoietic stem and progenitor cells [BM_MPB]

Project description:Here we present the single cell transcriptomes of human adult mobilized peripheral blood (mPB) and bone marrow (BM) hematopoietic stem and progenitor cell (HSPC) subsets,: long-term haematopoietic stem cells (LT-HSCs), short-term HSCs (ST-HSCs) and CD34+ cells before (0 h) and after 62 hours (62 h) of culture in a conditions mimicking gene therapy protocols. The culture protocol includes two hits of lentiviral transduction (lentiviral vector contains a GFP construct) and media as previously published . The objectives of this study are to investigate the effects of lentiviral transduction and cell culture in gene therapy protocol conditions on human mPB and BM haematopoietic stem and progenitor cell (HSPC) subsets. In the present study we report that 62 h of culture in gene therapy media significantly alters the transcriptome of BM and mPB subsets. In contrast, lentiviral transduction alone has a minimal effect on the transcriptome of all tested subsets. T=transduced GFP+; NT=non transduced; GFP-= transduced GFP-

Generation of induced pluripotent stem cells by efficient reprogramming of adult bone marrow cells

Project description:Reprogramming of somatic cells provides potential for the generation of specific cell types, which could be a key step in the study and treatment of human diseases. In vitro reprogramming of somatic cells into a pluripotent embryonic stem (ES) cell–like state has been reported by retroviral transduction of murine fibroblasts using four embryonic transcription factors or through cell fusion of somatic and pluripotent stem cells. The generation of reprogrammed pluripotent cells using a somatic cell donor source such as bone marrow (BM) or peripheral blood is of particular therapeutic interest because of the relative ease of harvesting these cell types. Here we show that mouse adult BM mononuclear cells（BM MNCs）are competent as donor cells and can be reprogrammed into pluripotent ES cell-like cells. We isolated BM MNCs and embryonic fibroblasts (MEFs) from Oct4-EGFP transgenic mice, fused them with ES cells and infected them with retroviruses expressing Oct4, Sox2, Klf4, and c-Myc. Fused BM cells formed more ES-like colonies than did MEFs. Infected BM cells gave rise to iPS cells, although transduction efficiencies were not high. It was more efficient to pick up iPS colonies as compared with MEFs. BM-derived iPS (BM iPS) cells expressed embryonic stem cell markers, formed teratomas, and contributed to chimera mice with germline development. Clonal analysis revealed that BM iPS clones had diversity, although some clones were found to be genetically identical with different phenotypes. Here we demonstrate, for the first time, the induction of pluripotent cells directly from hematopoietic tissue.

Transgene-free iPSCs generated from small volume peripheral blood nonmobilized CD34+ cells

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.

Comparison of monocytes from G-CSF mobilized and normal peripheral blood

Project description:A prospective randomized trial has shown that there is a survival advantage for allogeneic transplant patients receiving Granulocyte Colony Stimulating Factor (G-CSF) stimulated peripheral blood mononuclear cells (GPBMC) versus bone marrow (BM) as a source of stem cells. The biological basis for this advantage is not clear, and may be attributable to qualitative as well as quantitative differences in the CD34 cells, T-cells and/or the monocytes transplanted. To begin to address this issue, gene expression patterns in monocytes isolated from G-CSF mobilized peripheral blood were compared those from normal, non-mobilized peripheral blood to identify functional pathways that may distinguish these two populations.
