    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: 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: 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〉

    Description: Lineage-specific regulatory elements can be used to direct expression of a variety of genes to specific tissues in transgenic mice. If the hybrid constructs contain a gene encoding a cytotoxic gene product, then genetic ablation of a specific cell lineage can be achieved. We have generated six transgenic mice by introducing into fertilized eggs the mouse gamma 2-crystallin promoter fused to the coding region of the diphtheria toxin A-chain gene. Three of these mice and all the transgenic offspring analyzed were microphthalmic. The lenses of these mice displayed considerable heterogeneity: some were almost normal morphologically but reduced in size, whereas others were grossly aberrant and deficient in nuclear fiber cells. These studies indicate that programmed ablation of specific cell types can be stably transmitted through the germ line.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Breitman, M L -- Clapoff, S -- Rossant, J -- Tsui, L C -- Glode, L M -- Maxwell, I H -- Bernstein, A -- CA 42354/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1987 Dec 11;238(4833):1563-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Mount Sinai Hospital Research Institute, Toronto, Ontario, Canada.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3685993" target="_blank"〉PubMed〈/a〉

    Description: Transgenic mice carrying the gamma 2-crystallin promoter fused to the coding region of the bacterial lacZ gene were generated. The offspring of three founder mice expressed high levels of the enzyme solely in the central nuclear fiber cells of the lens as measured by an in situ assay for the detection of beta-galactosidase activity. These results suggest that gamma 2-crystallin sequences between -759 to +45 contain essential information required for appropriate tissue-specific and temporal regulation of the mouse gamma 2-crystallin gene. In a broader context, this study also demonstrates the utility of beta-galactosidase hybrid gene constructs for monitoring the activity of gene regulatory elements in transgenic mice.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Goring, D R -- Rossant, J -- Clapoff, S -- Breitman, M L -- Tsui, L C -- New York, N.Y. -- Science. 1987 Jan 23;235(4787):456-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3099390" target="_blank"〉PubMed〈/a〉

    Notes: [Auszug] Haploid blastocysts can now be routinely obtained after parthenogenetic activation of unfertilised eggs (for review, see refs 1-3). When transferred to ectopic sites such embryos give rise in a small proportion of cases to 'growths' composed of many types of differentiated tissues, some of which ...

    Notes: [Auszug] In mice, there is evidence suggesting that the development of head and trunk structures is organized by distinctly separated cell populations. The head organizer is located in the anterior visceral endoderm (AVE) and the trunk organizer in the node and anterior primitive streak. In ...
