Outline of Final Research Achievements |
We have formulated a mechanical model of Drosophila wing margin shape by modelling the margin as a string-like object with bending stiffness. Further, assuming the wing blade as a homogeneous visco-elastic material, we have extended the model by assigning constant tension to the wing blade. Extending the model to a wider variety of insect wing margin shapes, we have inferred the bending stiffness of such margins and constructed a simple hybrid model of wing margin and blade by using the cell vertex model (with Dr. Sugimura). As a cell-based model to realise viscoelastic dynamics of a tissue/organ-sized object, we have constructed the bubbly vertex model. Based on its implication, we have studied mouse olfactory system and its patterning dynamics (with Dr. Togashi et al.). Also, we have quantified the deformation of mouse tooth germ organogenesis (with Dr. Tsuji et al.). We have submitted four papers to academic journals, three of which had been published by the end of the period.
