    Promotion of trophoblast stem cell proliferation by FGF4 (1998)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1998-12-16
    Description: The trophoblast cell lineage is essential for the survival of the mammalian embryo in utero. This lineage is specified before implantation into the uterus and is restricted to form the fetal portion of the placenta. A culture of mouse blastocysts or early postimplantation trophoblasts in the presence of fibroblast growth factor 4 (FGF4) permitted the isolation of permanent trophoblast stem cell lines. These cell lines differentiated to other trophoblast subtypes in vitro in the absence of FGF4 and exclusively contributed to the trophoblast lineage in vivo in chimeras.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tanaka, S -- Kunath, T -- Hadjantonakis, A K -- Nagy, A -- Rossant, J -- New York, N.Y. -- Science. 1998 Dec 11;282(5396):2072-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Samuel Lunenfeld Research Institute, Mount Sinai Hospital, Toronto, Ontario M5G 1X5, Canada.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9851926" target="_blank"〉PubMed〈/a〉

    Regulation of a transcription factor network required for differentiation and metabolism (1998)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1998-07-31
    Description: Hepatocyte nuclear factors (HNFs) are a heterogeneous class of evolutionarily conserved transcription factors that are required for cellular differentiation and metabolism. Mutations in HNF-1alphaand HNF-4alpha genes impair insulin secretion and cause type 2 diabetes. Regulation of HNF-4/HNF-1 expression by HNF-3alpha and HNF-3beta was studied in embryoid bodies in which one or both HNF-3alpha or HNF-3beta alleles were inactivated. HNF-3beta positively regulated the expression of HNF-4alpha/HNF-1alpha and their downstream targets, implicating a role in diabetes. HNF-3beta was also necessary for expression of HNF-3alpha. In contrast, HNF-3alpha acts as a negative regulator of HNF-4alpha/HNF-1alpha demonstrating that HNF-3alpha and HNF-3beta have antagonistic transcriptional regulatory functions in vivo. HNF-3alpha does not appear to act as a classic biochemical repressor but rather exerts its negative effect by competing for HNF-3 binding sites with the more efficient activator HNF-3beta. In addition, the HNF-3alpha/HNF-3beta ratio is modulated by the presence of insulin, providing evidence that the HNF network may have important roles in mediating the action of insulin.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Duncan, S A -- Navas, M A -- Dufort, D -- Rossant, J -- Stoffel, M -- New York, N.Y. -- Science. 1998 Jul 31;281(5377):692-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratories of Molecular Cell Biology and Metabolic Diseases, Rockefeller University, New York, NY 10021, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9685261" target="_blank"〉PubMed〈/a〉

    Cardiac malformation in neonatal mice lacking connexin43 (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1995-03-24
    Description: Gap junctions are made up of connexin proteins, which comprise a multigene family in mammals. Targeted mutagenesis of connexin43 (Cx43), one of the most prevalent connexin proteins, showed that its absence was compatible with survival of mouse embryos to term, even though mutant cell lines showed reduced dye coupling in vitro. However, mutant embryos died at birth, as a result of a failure in pulmonary gas exchange caused by a swelling and blockage of the right ventricular outflow tract from the heart. This finding suggests that Cx43 plays an essential role in heart development but that there is functional compensation among connexins in other parts of the developing fetus.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Reaume, A G -- de Sousa, P A -- Kulkarni, S -- Langille, B L -- Zhu, D -- Davies, T C -- Juneja, S C -- Kidder, G M -- Rossant, J -- New York, N.Y. -- Science. 1995 Mar 24;267(5205):1831-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Samuel Lunenfeld Research Institute, Mount Sinai Hospital, Toronto, Ontario, Canada.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7892609" target="_blank"〉PubMed〈/a〉

    Hallmarks of pluripotency (2015)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2015-09-25
    Description: Stem cells self-renew and generate specialized progeny through differentiation, but vary in the range of cells and tissues they generate, a property called developmental potency. Pluripotent stem cells produce all cells of an organism, while multipotent or unipotent stem cells regenerate only specific lineages or tissues. Defining stem-cell potency relies upon functional assays and diagnostic transcriptional, epigenetic and metabolic states. Here we describe functional and molecular hallmarks of pluripotent stem cells, propose a checklist for their evaluation, and illustrate how forensic genomics can validate their provenance.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉De Los Angeles, Alejandro -- Ferrari, Francesco -- Xi, Ruibin -- Fujiwara, Yuko -- Benvenisty, Nissim -- Deng, Hongkui -- Hochedlinger, Konrad -- Jaenisch, Rudolf -- Lee, Soohyun -- Leitch, Harry G -- Lensch, M William -- Lujan, Ernesto -- Pei, Duanqing -- Rossant, Janet -- Wernig, Marius -- Park, Peter J -- Daley, George Q -- Howard Hughes Medical Institute/ -- England -- Nature. 2015 Sep 24;525(7570):469-78. doi: 10.1038/nature15515.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Stem Cell Transplantation Program, Division of Pediatric Hematology Oncology, Children's Hospital Boston, and Dana-Farber Cancer Institute; Department of Biological Chemistry and Molecular Pharmacology, Harvard Medical School, Boston, Massachusetts 02115, USA. ; Harvard Stem Cell Institute, Cambridge, Massachusetts 02138, USA. ; Howard Hughes Medical Institute, Boston, Massachusetts 02115, USA. ; Department of Biomedical Informatics, Harvard Medical School, Boston, Massachusetts 02115, USA. ; School of Mathematical Sciences and Center for Statistical Science, Peking University, Beijing 100871, China. ; Stem Cell Unit, Department of Genetics, Institute of Life Sciences, The Hebrew University, Jerusalem 91904, Israel. ; College of Life Sciences and Peking-Tsinghua Center for Life Sciences, Peking University, Beijing 100871, China. ; Massachusetts General Hospital Cancer Center and Center for Regenerative Medicine, Boston, Massachusetts 02114, USA. ; Whitehead Institute for Biomedical Research, Cambridge, Massachusetts 02142, USA. ; Medical Research Council Clinical Sciences Centre, Imperial College London, London W12 0NN, United Kingdom. ; Institute for Stem Cell Biology and Regenerative Medicine, Stanford University, Stanford, California 94305, USA. ; South China Institute for Stem Cell Biology and Regenerative Medicine, Guangzhou Institutes of Biomedicine and Health, Chinese Academy of Sciences, Guangzhou 510530, China. ; The Hospital for Sick Children Research Institute, Toronto, Ontario ON M5G 0A4, Canada.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/26399828" target="_blank"〉PubMed〈/a〉
