    Epithelial cells in nerve-free hydra produce morphogenetic substances (1980)
    [s.l.] : Nature Publishing Group
    Nature 283 (1980), S. 589-591

    Notes: [Auszug] In a preliminary investigation we have shown that severely nerve-depleted hydra, which consist almost exclusively of epithelial cells, contain normal concentrations of morphogenetic substances7. To exclude the possibility that the few remaining nerve cells overproduce these substances, we have ...

    Properties of the foot inhibitor from hydra (1980)
    Springer
    Development genes and evolution 188 (1980), S. 133-139 
    Details
    ISSN: 1432-041X
    Keywords: Hydra ; Morphogenetic substances ; Regeneration ; Pattern formation ; Sea anemones

    Topics: Biology
    Notes: Summary A substance was isolated from crude extracts of hydra that inhibits foot regeneration. This substance, the foot inhibitor, has a molecular weight of ≦500 daltons. It is a hydrophilic molecule, slightly basic in character and it has no peptide bonds. The pruified substance acts specifically and at concentrations lower than 10−7 M. At this low concentration only foot and not head regeneration is inhibited. Hydra are sensitive to purified foot inhibitor between the second and eight hour after initiation of foot regeneration by cutting. In normal animals the foot inhibitor is most likely produced by nerve cells. A substance with similar biological and physico-chemical properties is found in other coelenterates.
