Tissue-Specific Transcriptional Profiling of Epigenetic Asymmetry in Porcine Parthenogenetic Fetuses1

ABSTRACT: Using two complementary approaches, analysis of imprinting of candidate genes by pyrosequencing and expression profiling of parthenogenetic fetuses, we carried a comprehensive survey of genomic imprinting in swine. In the case of imprinted genes where transcription of one of the two parental alleles is silenced, uniparental embryos like parthenotes can be used to measure transcript dosage effects. Using Affymetrix Porcine GeneChip microarrays, four tissues of day 30 fetuses were profiled: brain, fibroblast, liver, and placenta. Keywords: Transcriptional profiling of epigenetic asymmetry in porcine day 30 parthenogenetic and biparental fetal tissues

Expression analysis in parthenogenetic cells through different potency stages

Project description:Parthenogenetic stem cells were derived from parthenotes, then differentiated to mesenchymal stem cells. These were further reprogrammed to induced pluripotent stem cells, which were finally differentiated to secondary mesenchymal stem cells. Transcriptional analysis was performed at all 4 states of potency to indetify changes in expression stability of partehnogenetic cells. 4 samples for each stage of potency were analyzed, controls were biparental embryonic stem cells and their mesenchymal derivate, as well as biparental induced pluripotent stem cells

Generation of parthenogenetic iPS cells from parthenogenetic neural stem cell

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.

Parthenogenetic stem cells for tissue-engineered heart repair

Project description:Uniparental parthenotes are considered an unwanted byproduct of in vitro fertilization. In utero parthenote development is severely compromised by defective organogenesis and in particular by defective cardiogenesis. Although developmentally compromised, apparently pluripotent stem cells can be derived from parthenogenetic blastocysts. Here we hypothesized that nonembryonic parthenogenetic stem cells (PSCs) can be directed toward the cardiac lineage and applied to tissue-engineered heart repair. We first confirmed similar fundamental properties in murine PSCs and embryonic stem cells (ESCs), despite notable differences in genetic (allelic variability) and epigenetic (differential imprinting) characteristics. Haploidentity of major histocompatibility complexes (MHCs) in PSCs is particularly attractive for allogeneic cell-based therapies. Accordingly, we confirmed acceptance of PSCs in MHC-matched allotransplantation. Cardiomyocyte derivation from PSCs and ESCs was equally effective. The use of cardiomyocyte-restricted GFP enabled cell sorting and documentation of advanced structural and functional maturation in vitro and in vivo. This included seamless electrical integration of PSC-derived cardiomyocytes into recipient myocardium. Finally, we enriched cardiomyocytes to facilitate engineering of force-generating myocardium and demonstrated the utility of this technique in enhancing regional myocardial function after myocardial infarction. Collectively, our data demonstrate pluripotency, with unrestricted cardiogenicity in PSCs, and introduce this unique cell type as an attractive source for tissue-engineered heart repair. 8 samples in total. Parthenogenetic stem cells (PSC): - PSC_1 - PSC_2 - PSC_3 Embryoid body (EB) assays of parthenogenetic stem cells: - EB_PSC_1 - EB_PSC_2 Embryonic stem cells (ESC): - ESC_1 - ESC_2 - ESC_3
