    Christoforos Bouzanis (forthcoming). Ontogenesis Versus Morphogenesis Towards an Anti-Realist Model of the Constitution of Society. Human Studies:1-31.
    This article firstly criticizes Margaret Archer’s Morphogenetic Approach for being indecisive about the realist notion of emergence it proposes as well as for her inadequate account of structural conditioning. It is argued that critical realists’ conceptualizations of emergence cannot but lead to inconsistencies about the adequate placement of agents as parts of emergent entities. The inconsistencies to which these conceptualizations lead necessitate an anti-realist model of the constitution of societies which takes into account that social structures are existentially dependent upon (...)

    Takashi Miura (2013). Modeling Lung Branching Morphogenesis. Biological Theory 8 (3):265-273.
    Biological forms are very complex, and mechanisms of pattern formation are not well understood. Although developmental biology deals with the mechanistic explanation of patterns, currently we do not know how to understand the mechanisms of pattern formation from huge amounts of molecular information. In this article, I present one useful tool, mathematical modeling, to obtain a mechanistic understanding of biological pattern formation, and show an actual example in lung branching morphogenesis. In this example, mathematical modeling plays an indispensable role (...)

    This paper is devoted to computer modelling of the development and regeneration of multicellular biological structures. Some species are able to regenerate parts of their body after amputation damage, but the global rules governing cooperative cell behaviour during morphogenesis are not known. Here, we consider a simplified model organism, which consists of tissues formed around special cells that can be interpreted as stem cells. We assume that stem cells communicate with each other by a set of signals, and that (...)

    Michel Ferré & Hervé Guyader (1990). Plant Morphogenesis: A Geometrical Model for the Ramification. Acta Biotheoretica 38 (3-4).
    A geometrical model is proposed that describes the emergence of a primordium at the shoot apex in Dicotyledons. It is based on recent fundamental results on plant morphogenesis, viz.: – the emergence is preceded by the reorganization of the microtubules of the cortical cytoskeleton, leading to a new orientation of the synthesis of the cell wall microfibrils; – the resulting global stress is related to the general orientation of the cell growth.

    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 (...)

    Michel Ferre & Herve Guyader (1984). The Geometry of Leaf Morphogenesis: A Theoretical Proposition. Acta Biotheoretica 33 (2).
    Plant morphogenesis exhibits numerous bifurcations with particular angle values such as 41°, 53°, which, in lower plants, can be measured in the thallus, and, in higher plants, in the ribs of the leaves. An interpretation of these angles is attempted. Since they characterize the functioning of a morphogenetic field, a formalism was constructed suitable for the study of living systems. The mathematical tool devised here, named the Arithmetical Relator, combines Geometry and Arithmetic, and assumes that a general system results (...)

    Loïc Forest & Jacques Demongeot (2008). A General Formalism for Tissue Morphogenesis Based on Cellular Dynamics and Control System Interactions. Acta Biotheoretica 56 (1):51-74.
    Morphogenesis is a key process in developmental biology. An important issue is the understanding of the generation of shape and cellular organisation in tissues. Despite of their great diversity, morphogenetic processes share common features. This work is an attempt to describe this diversity using the same formalism based on a cellular description. Tissue is seen as a multi-cellular system whose behaviour is the result of all constitutive cells dynamics. Morphogenesis is then considered as a spatiotemporal organization of cells (...)

    Patterns resulting from the sole interplay between reaction and diffusion are probably involved in certain stages of morphogenesis in biological systems, as initially proposed by Alan Turing. Self-organization phenomena of this type can only develop in nonlinear systems (i.e. involving positive and negative feedback loops) maintained far from equilibrium. We present Turing patterns experimentally observed in a chemical system. An oscillating chemical reaction, the CIMA reaction, is operated in an open spatial reactor designed in order to obtain a pure (...)

    One can use mathematics not as an instrument or measure, or a replacement for God, but as a poetic articulation, or perhaps as a stammered experimental approach to cultural dynamics. I choose to start with the simplest symbolic substances that respect the lifeworld’s continuous dynamism, temporality, boundless morphogenesis, superposability, continuity, density and value, and yet are independent of measure, metric, counting, finitude, formal logic, syntax, grammar, digitality and computability – in short, free of the formal structures that would put (...)

    The highly ordered neuronal projections from the retina to the tectum mesencephali (optic tectum) in several vertebrate groups have been intensively studied. Several hypotheses so far have been proposed, suggesting mechanisms to explain the topographical and biochemical specificity of the retinotectal projections during ontogeny. In the present paper we compare the main hypotheses of retinotectal development with respect to the nature of specificity envisaged, the activity-dependence versus inheritance criterium and the strategy of argument, in casu the descriptive versus interferential type (...)

    This contribution illuminates the meaning of the systematic confrontation with nature in the artistic and art-theoretical thought of Paul Klee. Klee’s specific interest lay in the analysis of the morphological and structural principles of plants as well as in the study of the processes of growth and form in nature. A central element of this confrontation—which also manifested itself in nuanced ways in Klee’s teaching at the Bauhaus and in his artistic creations—is the reduction of the manifold natural world of (...)

    A theoretical model is presented for pattern formation in an epithelium. The epithelial model consists of a thin, incompressible, viscoelastic membrane on an elastic foundation (substrate), with the component cells assumed to have active contractile properties similar to those of smooth muscle. The analysis includes the effects of large strains and material nonlinearity, and the governing equations were solved using finite differences. Deformation patterns form when the cells activate while lying on the descending limb of their total (active + passive) (...)

    Regeneration in arthropods and amphibians follows an analogous principle making comparisons between the two phyla possible.Larval arthropods and amphibians possess powers of epimorphic regeneration which wane for many species of these phyla with the completion of metamorphosis or the cessation of moulting. In those species which retain, post-maturationally, the ability to form a regenerative blastema, larval characteristics are carried into the adult and reproductive stages of these organisms. These include many species of: urodeles, ametabolous insects, crustaceans, myriapods and arachnids. The (...)

    Data from experiments on Erica × darleyensis and from related observations (Viémont and Beaujard, 1983) are taken for a critical analysis of the proposed model of morphogenetic phenomena. The criteria for judging the coherence of the constructions proposed in plant morphology are based on mathematical constructions deduced from Petri nets, especially elementary nets.
