Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
Human induced pluripotent stem (iPS) cells have previously been derived from somatic cells using viral vectors that integrate transgenes into the genome. Genomic integration, however, can allow persistent leaky expression of the transgenes and can create insertional mutations, thus limiting the utility of these cells for both research and clinical applications. Here, we describe the derivation of human iPS cells free of vector and transgene sequences using non-integrating oriP/EBNA1-based episomal vectors. The resulting iPS cells are similar to human embryonic stem (ES) cells in both proliferative and developmental potential. These results demonstrate that reprogramming of human somatic cells does not require genomic integration or the continued presence of exogenous reprogramming factors, and removes one important obstacle to the clinical applications of these cells.

Description
Recently, we identified mesenchymoangioblast (MAB), as a clonal mesodermal precursor for mesenchymal and endothelial cells. Here we show, that MABs have the capacity to produce mesenchymal progenitors, which can be differentiated into pericytes or smooth muscles cells under the influence of PDGF-BB or TGFß plus sphingosylphosphorylcholine (SPC), respectively. Based on these studies we established the hierarchy of vasculogenic progenitors that provides the platform for interrogation of molecular mechanisms regulating vasculogenic cell specification and diversification from primitive posterior mesoderm. Overall design: Vasculogenic cells generated under specific culture conditions. Primary cells were used as control.

Description
Hemogenic endothelium (HE) is the source of HSCs in the developing embryo. In this study we have identified the hemogenic endothelial progenitors and their precursors originating from differentiated H1 cells on OP9 stromal cells. Overall design: RNA-seq of hemogenic endothelial progenitors and their precursors originating from differentiated H1 cells on OP9 stromal cells.

Description
Analysis of lin-CD34+CD45+ (iCD34+) cell population from two normal bone marrow-derived (BM1K and BM9) iPSCs and two CML (CML15 and CML17) iPSCs . CML iCD34+ cells have characteristics similar to primary CML leukemia stem cell in patients. Results provide insight into molecular profile characterized CML iCD34 and mechanism of its maintenance and drug resistance. Overall design: iCD34+ cell samples obtained from two control BM1K and BM9 iPSCs (both for the same normal donor) and CML15 and CML17 iPSCs (both from the same patient in chronic phase of CML). Each group was treated with DMSO (control) or 5 µM imatinib. The complete phenotype for iCD34+ cells: lin-CD34+CD45+CD90+CD117+CD45RA-. This population also inclyde Rhodaminelow and ALDKhigh cells.

Description
The deposit microarray data were generated in a study that comprehensively integrated gene expression profiles and metabolic responses of Caco-2 cells that incubated with either E. coli K-12 or O157:H7. The aim of this study is to examine the impact of colonic bacteria on the global gene expression regulation and metabolite levels of the host, and investigate the molecular mechanics of the E. coli/host interaction.
