Characterizing the mechanical properties of tissues is key for understanding fundamental biological processes such as morphogenesis or tumor progression. In particular, intercellular adhesion forces, mediated by transmembrane proteins like cadherins, are expected to control topology and viscoelastic behavior under stress. order understand influence in tissues, we use biomimetic emulsions which ...

The giant ciliated protozoan Stentor coeruleus is re-emerging as a model organism for morphogenesis and patterning in unicellular organisms. A new study provides evidence that cytokinesis and morphogenesis are mechanistically linked through the Mob1 protein.

Preinfection development in Colletotrichum spp. exhibits three morphologies (conidia, germ tubes, and appressoria) and is directed by a complex interplay of environmental signals. Germ tube morphogenesis for Colletotrichum trifolii and the related fungus Colletotrichum gloeosporioides f. sp. aeschynomene was shown to be partially dependent on a balance between self-germination inhibitors and en...

The morphogenetic role of the acid mucopolysaccharide (glycosaminoglycan) at the epithelial surface of mouse embryo submandibular glands has been studied by comparing the in vitro morphogenesis of epithelia from which the mucopolysaccharide was removed with that of those that retained the mucopolysaccharide . Epithelia isolated free of mesenchyme by procedures which retain the bulk of surface m...
