    • Bicoid 

      Resnik, Jack (Arizona State University. School of Life Sciences. Center for Biology and Society. Embryo Project Encyclopedia., 2012-08-13)
      Bicoid is the protein product of a maternal-effect gene unique to flies of the genus Drosophila . In 1988 Christiane Nüsslein-Volhard identified bicoid as the first known morphogen . A morphogen is a molecule that ...
    • Christiane Nusslein-Volhard (1942- ) 

      Resnik, Jack; May, Catherine (Arizona State University. School of Life Sciences. Center for Biology and Society. Embryo Project Encyclopedia., 2014-06-11)
      Christiane Nusslein-Volhard studied how genes control embryonic development in flies and in fish in Europe during the twentieth and twenty-first centuries. In the 1970s, Nusslein-Volhard focused her career on studying the ...
    • "Gene Regulation for Higher Cells: A Theory" (1969), by Roy J. Britten and Eric H. Davidson 

      Wolter, Justin (Arizona State University. School of Life Sciences. Center for Biology and Society. Embryo Project Encyclopedia., 2013-09-10)
      In 1969, Roy J. Britten and Eric H. Davidson published Gene Regulation for Higher Cells: A Theory, in Science. A Theory proposes a minimal model of gene regulation, in which various types of genes interact to control ...
    • Mesenchyme 

      MacCord, Kate (Arizona State University. School of Life Sciences. Center for Biology and Society. Embryo Project Encyclopedia., 2012-11-05)
      Mesenchyme is a type of animal tissue comprised of loose cells embedded in a mesh of proteins and fluid, called the extracellular matrix. The loose, fluid nature of mesenchyme allows its cells to migrate easily and play a ...
    • The Notch Signaling Pathway in Embryogenesis 

      Wolter, Justin (Arizona State University. School of Life Sciences. Center for Biology and Society. Embryo Project Encyclopedia., 2013-03-18)
      The Notch signaling pathway is a mechanism in animals by which adjacent cells communicate with each other, conveying spatial information and genetic instructions for the animal's development. All multicellular animals ...
    • "On the Permanent Life of Tissues outside of the Organism" (1912), by Alexis Carrel 

      Jiang, Lijing (Arizona State University. School of Life Sciences. Center for Biology and Society. Embryo Project Encyclopedia., 2013-07-10)
      'On the Permanent Life of Tissues outside of the Organism' reports Alexis Carrel's 1912 experiments on the maintenance of tissue in culture media. At the time, Carrel was a French surgeon and biologist working at the ...
    • The Source-Sink Model 

      Resnik, Jack (Arizona State University. School of Life Sciences. Center for Biology and Society. Embryo Project Encyclopedia., 2012-08-13)
      The source-sink model, first proposed by biologist Francis Crick in 1970, is a theoretical system for how morphogens distribute themselves across small fields of early embryonic cells. A morphogen is a substance that ...
