    Separation and specificity of action of four morphogens from hydra (1979)
    Springer
    Development genes and evolution 186 (1979), S. 139-149 
    Details
    ISSN: 1432-041X
    Schlagwort(e): Hydra ; Morphogenetic substances ; Regeneration ; Budding
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Biologie
    Notizen: Summary A procedure is presented by which four previously described morphogenetic substances can be purified from hydra: an activator and an inhibitor of head formation and an activator and an inhibitor of foot formation. We show that all four substances act specifically. At low concentrations, the head factors only influence head and not foot formation, and the foot factors only influence foot and not head formation.

    Properties of the foot inhibitor from hydra (1980)
    Springer
    Development genes and evolution 188 (1980), S. 133-139

    Notizen: 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.

    The head and the foot inhibitor from hydra are not dowex artefacts (1984)
    Springer
    Development genes and evolution 193 (1984), S. 117-118 
    Details
    ISSN: 1432-041X
    Schlagwort(e): Hydra ; Regeneration ; Head inhibitor ; Foot inhibitor

    Thema: Biologie
    Notizen: Summary In a recent publication in this journal (Berking 1983) it was claimed (1) that the head inhibitor we isolated from hydra is a Dowex artefact, (2) that a separate foot inhibitor does not exist in hydra and (3) that the only inhibitor that has so far been isolated from hydra is one which inhibits head and foot regeneration equally well. These statements are incorrect and require a response. In the following, I would like to summarise our evidence that the inhibitors isolated from hydra, including Berking's inhibitor, have different specificities for head and foot regeneration. In addition, I would like to show that none of our substances are Dowex artefacts.
