Context:   Collinet and Lecuit (2021) pose a question: what forces or mechanisms at the cellular level manage four very general classes of tissue deformation, namely tissue folding and invagination, tissue flow and extension, tissue hollowing, and, finally, tissue branching?
Full context:   The problem of morphogenesis – Cell actions during an embryo formation, including shape changes, cell contact remodeling, cell migration, cell division, and cell extrusion, need control over cell mechanics. This complex dynamical process is associated with protrusive, contractile, and adhesive forces and hydrostatic pressure, as well as material properties of cells that dictate how cells respond to active stresses. Precise coordination of all cells is a necessary condition. Moreover, such a complex dynamical process likely requires clear parameters of the final biological structure – the complete developmental program with a template for accomplishing it. Collinet and Lecuit (2021) pose a question: what forces or mechanisms at the cellular level manage four very general classes of tissue deformation, namely tissue folding and invagination, tissue flow and extension, tissue hollowing, and, finally, tissue branching? They challenge the nativists' notion that shape is fully encoded and determined by genes: how are cell mechanics and associated cell behaviors robustly organized in space and time during tissue morphogenesis? They argue that not only gene expression and the resulting biochemical cues but also mechanics and geometry act as sources of morphogenetic information to ultimately define the time and length scales of the cell behaviors driving morphogenesis. Thus, it is not only the interaction of gene activity with events and experiences in the environment that contributes to the formation of tissues in morphogenesis. Because the nervous system structures operate over everything that makes us human, the formation of neural tissues in a certain way is essential for shaping cognitive functions. According to research professor Igor Val Danilov, such a complex process of shaping the determined structure of the nervous system requires a complete developmental program with a template for accomplishing the final biological structure of the nervous system. Indeed, because even processes of the cell coupling for shaping a nervous system during embryonal development challenge the naturalistic approach, how the nervous system grasps perception and shapes intentionality (independently, i.e., without any template) seems even more complicated.
