Project description:Clinical application of induced pluripotent stem (iPS) cells is limited by low efficiency of iPS derivation, and protocols that permanently modify the genome to effect cellular reprogramming. Moreover, safe and effective means of directing the fate of patient-specific iPS cells towards clinically useful cell types are lacking. Here we describe a simple, non-mutagenic strategy for reprogramming cell fate based on administration of synthetic mRNA modified to overcome innate anti-viral responses. We show that this approach can reprogram multiple human cell types to pluripotency with efficiencies that greatly surpass established protocols. We further show that the same technology can be used to efficiently direct the differentiation of RNA-induced pluripotent stem (RiPS) cells into terminally differentiated myogenic cells. Our method represents a safe, efficient strategy for somatic cell reprogramming and directing cell fates that has broad applicability for basic research, disease modeling and regenerative medicine. We isolated RNA from human RNA derived iPS cells, viral derived iPS cells, different human fibroblasts and human embryonic stem cells for hybridization to the Affymetrix gene expression microarrays.

Project 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. This SuperSeries is composed of the following subset Series:; GSE15175: Human induced pluripotent stem cells free of exogenous DNA are derived with episomal vectors (fig 1.c); GSE15176: Human induced pluripotent stem cells free of exogenous DNA are derived with episomal vectors (fig 4.a) Experiment Overall Design: Total 21 samples were analyzed to confirm the similarity of human iPS cells derived with episomal vectors with human ES cells, and a dissimilarity with fibroblasts. Experiment Overall Design: Refer to individual Series

Project description:It has been shown that DNA demethylation has a pivotal role in the generation of induced pluripotent stem (iPS) cells. However, the underlying mechanism is still unclear. Previous reports indicated that activation-induced cytidine deaminase (Aid) is involved in DNA demethylation in several developmental processes and cell fusion-mediated reprogramming. Based on the reports, we hypothesized that Aid may be involved in DNA demethylation during the iPS cell generation. In this study, we examined the function of Aid in iPS cell generation using Aid knockout (Aid-/-) mice expressing a GFP reporter under the control of a pluripotent stem cell marker, Nanog. By the introduction of Oct3/4, Sox2, Klf4 and c-Myc, Nanog-GFP positive iPS cells could be generated from the fibroblasts and primary B cells of Aid-/- mice. The Aid-/- iPS cells showed normal proliferation and gave rise to chimeras, indicating their capacity for self-renewal and pluripotency. The comprehensive DNA methylation analysis by MBD-sequening demonstrated that there were only a few differences between Aid+/+ and Aid-/- iPS cells.
