  1. Determination, Regulation, and Positional Information in Insect Development.Willem J. Ouweneel - 1972 - Acta Biotheoretica 21 (1-2):115-131.
    Some aspects of insect development were reconsidered in relation toWolpert's concept of “positional information”, which was briefly summarized. His distinction between positional information and “polarity potential” was shown to be unnecessary. The question was discussed whether transdetermination inDrosophila imaginai discs is a re-specification or a re-interpretation of positional information. In the first case transdetermination would depend on spatial relationships in the blastema, whereas in the second case it would not. As to the so-called “prepattern mutants”, it was emphasized that in (...)

  • Cell Sociology: A Way of Reconsidering the Current Concepts of Morphogenesis.Rosine Chandebois - 1976 - Acta Biotheoretica 25 (2-3):71-102.
    Research in the field of planarian regeneration on the one hand, and a general survey of embryology on the other, throw doubt upon the reality of supra-cellular controls, which are still at the basis of all modern concepts of morphogenesis. The necessity of referring to such controls, which have never been convincingly demonstrated, is probably due to the fact that two aspects of cell behaviour have been underestimated: 1) the capacity of cells to change their individualities for a time independently (...)

  • The “Organization Centre”.P. D. Nieuwkoop - 1967 - Acta Biotheoretica 17 (4):178-194.
    Experimental evidence strongly supports the view that the subdivision of organ anlagen into smaller structural units is an autonomous process. Dalcq &Pasteels' hypothesis which says that the boundaries between the different areas into which a morphogenetic field differentiates are determined by “Threshold values” in the “potential” of the field in question, is inconsistent with our present knowledge of biochemical reaction systems. Threshold values may only be used indescribing the spatial differentiation of a morphogenetic field. It is suggested that the latter (...)
