How do tubes — gut or neural tube — form from flat sheets of polarized cells? The prevalent view is that it is a two-step process: first cells wedge to bend the sheet, then cells intercalate and extend the initial invagination into a tube. We computationally challenged this model by asking if one mechanism (either cell wedging or intercalation) may suffice for the entire sheet-to-tube transition. Using a physical model with epithelial cells represented by polarized point particles, we show that…

The notochord’s mechanical properties are associated with polarity establishment and transformation, which bridge signaling regulation and tissue mechanical properties that enable the coordinated organogenesis during embryo development.
Self-assembly, buckling and density-invariant growth of three-dimensional vascular networks
- BiologyJournal of the Royal Society Interface
- 2019
This model demonstrates convergent extension in the self-assembling process of blood vessels in three dimensions through a set of simple rules that align intercellular apical–basal and planar cell polarity and suggests that the mechanism behind the vascular density-maintaining growth of these islets could be the result of growth-induced buckling.

It is envisioned that more detailed high-resolution quantitative data at both cell and tissue levels will be required to properly model mechanisms of vertebrate neural plate internalization with the hope to prevent human neural tube defects.

It is shown that in addition to apical constriction, radially oriented directional intercalation of cells plays a major contribution to early stages of invagination of the salivary gland tube in the Drosophila embryo.

The theoretical tool suggests experimentally testable predictions pointing to the strength of polar adhesion, restricted directions of cell polarities, and the rate of cell proliferation to be major determinants of morphological diversity and stability.

It is found that the ventral furrow can form through stochastic self-organisation and that previous experimental observations can be readily explained in the model by considering forces that arise when cells execute contractions while being coupled to each other in a mechanically coherent epithelium.
