Transcription profiling of IPS cells derived from peripheral blood cells: Reprogramming of T Cells from Human Peripheral Blood

ABSTRACT: Human induced pluripotent stem (iPS) cells derived from somatic cells of patients hold great promise for modelling human diseases. Dermal fibroblasts are frequently used for reprogramming, but require an invasive skin biopsy and a prolonged period of expansion in cell culture prior to use. Here, we report the derivation of iPS cells from multiple human blood sources including peripheral blood mononuclear cells (PBMCs) harvested by routine venipuncture. Peripheral blood-derived human iPS lines are comparable to human embryonic stem (ES) cells with respect to morphology, expression of surface antigens, activation of endogenous pluripotency genes, DNA methylation and differentiation potential. Analysis of Immunoglobulin and T-cell receptor gene rearrangement revealed that some of the PBMC iPS cells were derived from T-cells, documenting derivation of iPS cells from terminally differentiated cell types. Importantly, peripheral blood cells can be isolated with minimal risk to the donor and can be obtained in sufficient numbers to enable reprogramming without the need for prolonged expansion in culture. Reprogramming from blood cells thus represents a fast, safe and efficient way of generating patient-specific iPS cells. We isolated RNA from multiple human blood sources including peripheral blood mononuclear iPS cells, multiple somatic cells and iPS cells and human embryonic cells and hybridized them to Affymetrix gene expression microarrays.

Project description:Induced pluripotent stem (iPS) cells have been generated from mouse and human somatic cells by ectopic expression of the transcription factors OCT4, SOX2, KLF4, c-MYC as well as NANOG and LIN28. Here we report generation of induced pluripotent stem cells from human umbilical cord blood derived unrestricted somatic stem cells (USSC) using retroviral expression of the transcription factors OCT4, SOX2, KLF4 and C-MYC and evaluation of their molecular signature and differentiation potential in comparison to human embryonic stem cells. The reprogrammed cells (HUiPS) were analysed morphologically, by qRT-PCR, global miRNA and epigenetic profiling and gene expression microarrays, as well as in their in vitro and in vivo differentiation potential by embryoid body formation and teratoma assay. The cord blood iPS cells are highly similar to human embryonic stem cells morphologically, at their molecular signature as well as in their in vitro and in vivo differentiation potential. Human cord blood derived unrestricted somatic stem cells offer an attractive source of cells for the generation of induced pluripotent stem cells. Our findings open novel perspectives to generate HLA matched pluripotent stem cell banks based on existing cord blood banks. Besides its obvious relevance of such a second generation cord blood iPS bank for pharmacological and toxicological testing, its application for autologous or allogenic regenerative cell transplantation appears feasible. For transcriptome profiling, 400 ng of total DNA-free RNA was used as input for labelled cRNA synthesis (Illumina TotalPrep RNA Amplification Kit - Ambion) following the manufacturer's instructions (IVT: 10h). Quality-checked cRNA samples were hybridized as biological or technical duplicates for 18 h onto HumanRef-8 v3 expression BeadChips (Illumina), washed, stained, and scanned following guidelines and using materials / instrumentation supplied / suggested by the manufacturer. Six sample types were analyzed, each one of them in duplicate.
