“…By tracing movements of several hundreds of the outer ectodermal cells belonging to artificially stretched explants of embryonic ectoderm, we could distinguish two sharply separated modes of cell movements: One of them having a characteristic rate of about 10-12 μm/min was oriented stretch direction while the other one containing randomly oriented movements with the rates non-exceeding 2-5 μm/ min (Fig. 3.10j, i) (Troshina et al 2011). Noteworthy, the latter value was greater in the stretched rather than non-stretched samples, permitting to exclude its artifact origin.…”

Morphogenesis in living tissues is the paramount example of a time- and space-dependent orchestration of living matter where shape and order emerge from undifferentiated initial conditions. The genes encode the protein expression that eventually drives the emergence of the phenotype, while energy supply and cell-to-cell communication mechanisms are necessary to such a process. The overall control of the system likely exploits the laws of chemistry and physics through robust and universal processes. Even if the identification of the communication mechanisms is a question of fundamental nature, a long-standing investigation settled in the realm of chemical factors only (also known as morphogens) faces a number of apparently unsolvable questions. In this paper, we investigate at what extent mechanical forces, alone or through their biological feedbacks, can direct some basic aspects of morphogenesis in development biology. In this branch of mechano-biology, we discuss the typical rheological regimes of soft living matter and the related forces, providing a survey on how local mechanical feedbacks can control global size or even gene expression. We finally highlight the pivotal role of nonlinear mechanics to explain the emergence of complex shapes in living matter
