Project description:In pluripotential reprogramming, a pluripotent state is established within somatic cells. In this study, we have generated induced pluripotent stem (iPS) cells from bi-maternal (uniparental) parthenogenetic neural stem cells (pNSCs) by transduction with four (Oct4, Klf4, Sox2, and c-Myc) or two (Oct4 and Klf4) transcription factors. The parthenogenetic iPS (piPS) cells directly reprogrammed from pNSCs were able to generate germline-competent himeras, and hierarchical clustering analysis showed that piPS cells were clustered more closer to parthenogenetic ES cells than normal female ES cells. Interestingly, piPS cells showed loss of parthenogenetic-specific imprinting patterns of donor cells. Microarray data also showed that the maternally imprinted genes, which were not expressed in pNSCs, were upregulated in piPS cells, indicating that pluripotential reprogramming lead to induce loss of imprinting as well as re-establishment of various features of pluripotent cells in parthenogenetic somatic cells. 5 samples were analyzed by microarray, each one them in duplicate. fNSC: Mouse female NSC (Neural Stem Cell) pNSC: Mouse parthenogenetic NSC (Neural Stem Cell) piPS-2F: Mouse parthenogenetic induced pluripotent cells derived from NSC overexpressing Oct4 and Klf4 pESC-B: Mouse parthenogenetic ESC (Embryonic Stem Cell) SSEA-1 sorted fESC: Mouse female ESC (Embryonic Stem Cell) OG2

Project description:Induced pluripotent stem (iPS) cells give rise to neural stem cells, which are applicable for therapeutic transplantation in treatment of neural diseases. However, generation of neural stem cells from iPS cells requires a careful selection of safe iPS clones. We sought to determine whether direct induction of neural stem cells from partially reprogrammed somatic cells is able to generate safer cells rapidly. We have successfully established direct induction system from fibroblast to neural stem cells. To characterize these directly induced neural stem cells, Gene expression profiles were compared with iPS cell or ES cell-derived neurosphere. We used affymetrix microarrays to compare the global gene expression of neurospheres prepared several method.

The mouse strain used in this study except ES/iPS cells was C57BL/6.

A two-chip study using total RNA recovered from one neural progenitor cell line derived from iPS cells generated from skin fibroblasts (GZF1C7NSCP3) and one neural progenitor cell line derived from iPS cells generated from umbilical cord mesenchymal cells (VMC2C7NSCP3). No replicates were made. Each chip measures the expression level of 45,033 genes from the two samples with fourteen 60-mer probe pairs (PM/MM) per gene, with three-fold technical redundancy.
