    Description: The embryonic role of endothelial cells and nascent vessels in promoting organogenesis, prior to vascular function, is unclear. We find that early endothelial cells in mouse embryos surround newly specified hepatic endoderm and delimit the mesenchymal domain into which the liver bud grows. In flk-1 mutant embryos, which lack endothelial cells, hepatic specification occurs, but liver morphogenesis fails prior to mesenchyme invasion. We developed an embryo tissue explant system that permits liver bud vasculogenesis and show that in the absence of endothelial cells, or when the latter are inhibited, there is a selective defect in hepatic outgrowth. We conclude that vasculogenic endothelial cells and nascent vessels are critical for the earliest stages of organogenesis, prior to blood vessel function.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Matsumoto, K -- Yoshitomi, H -- Rossant, J -- Zaret, K S -- CA06297/CA/NCI NIH HHS/ -- GM36477/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2001 Oct 19;294(5542):559-63.

    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〉

    Description: The two mouse genes, En-1 and En-2, that are homologs of the Drosophila segmentation gene engrailed, show overlapping spatially restricted patterns of expression in the neural tube during embryogenesis, suggestive of a role in regional specification. Mice homozygous for a targeted mutation that deletes the homeobox were viable and showed no obvious defects in embryonic development. This may be due to functional redundancy of En-2 and the related En-1 gene product during embryogenesis. Consistent with this hypothesis, the mutant mice showed abnormal foliation in the adult cerebellum, where En-2, and not En-1, is normally expressed.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Joyner, A L -- Herrup, K -- Auerbach, B A -- Davis, C A -- Rossant, J -- HD25334/HD/NICHD NIH HHS/ -- NS18381/NS/NINDS NIH HHS/ -- NS20591/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1991 Mar 8;251(4998):1239-43.〈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/1672471" target="_blank"〉PubMed〈/a〉

    Description: A strategy was devised for identifying regions of the mouse genome that are transcriptionally active in a temporally and spatially restricted manner during development. The approach is based on the introduction into embryonic stem cells of two types of lacZ reporter constructs that can be activated by flanking mouse genomic sequences. Embryonic stem cells containing the lacZ constructs were used to produce chimaeric mice. Developmental regulation of lacZ expression occurred at a high frequency. Molecular cloning of the flanking endogenous genes and introduction of these potential insertional mutations into the mouse germ line should provide an efficient means of identifying and mutating novel genes important for the control of mammalian development.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gossler, A -- Joyner, A L -- Rossant, J -- Skarnes, W C -- New York, N.Y. -- Science. 1989 Apr 28;244(4903):463-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Mount Sinai Hospital Research Institute, Division of Molecular and Developmental Biology, Toronto, Canada.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2497519" target="_blank"〉PubMed〈/a〉

    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〉

    Description: Activated CD8+ T cells play a critical role in host defense against viruses, intracellular microbes, and tumors. It is not clear if a key regulatory transcription factor unites the effector functions of CD8+ T cells. We now show that Eomesodermin (Eomes), a paralogue of T-bet, is induced in effector CD8+ T cells in vitro and in vivo. Ectopic expression of Eomes was sufficient to invoke attributes of effector CD8+ T cells, including interferon-gamma (IFN-gamma), perforin, and granzyme B. Loss-of-function analysis suggests Eomes may also be necessary for full effector differentiation of CD8+ T cells. We suggest that Eomesodermin is likely to complement the actions of T-bet and act as a key regulatory gene in the development of cell-mediated immunity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pearce, Erika L -- Mullen, Alan C -- Martins, Gislaine A -- Krawczyk, Connie M -- Hutchins, Anne S -- Zediak, Valerie P -- Banica, Monica -- DiCioccio, Catherine B -- Gross, Darrick A -- Mao, Chai-An -- Shen, Hao -- Cereb, Nezih -- Yang, Soo Y -- Lindsten, Tullia -- Rossant, Janet -- Hunter, Christopher A -- Reiner, Steven L -- AI-042370/AI/NIAID NIH HHS/ -- GM-07229/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2003 Nov 7;302(5647):1041-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Abramson Family Cancer Research Institute, and Department of Medicine, University of Pennsylvania, Philadelphia, PA 19104, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/14605368" target="_blank"〉PubMed〈/a〉
