Algal Morphogenesis: How Volvox Turns Itself Inside-Out
The coordinated movements of epithelial tissues play vital roles in a variety of processes, from embryonic development to wound healing. The multicellular green alga Volvox carteri is a useful model organism for studying one such movement: epithelial bending [2]. During embryogenesis, the immature spheroid Volvox undergoes a process known as inversion whereby it turns itself completely inside o...
متن کاملDynamics of a Volvox embryo turning itself inside out.
Deformations of cell sheets are ubiquitous in early animal development, often arising from a complex and poorly understood interplay of cell shape changes, division, and migration. Here, we explore perhaps the simplest example of cell sheet folding: the "inversion" process of the algal genus Volvox, during which spherical embryos turn themselves inside out through a process hypothesized to aris...
متن کاملDevelopment: Hippo Signalling Turns the Embryo Inside Out
Lineage decisions in development are thought to be primarily due to differential activation of transcription factors. However, cell position and subcellular organization of signalling also play a role. New studies of the Hippo pathway in the early mouse embryo show how.

Notation: In the sequel K is a field and Σn is the group of permutation over n elements. If A is an operad, then the K-vector space of n-ary operations is denoted as usual by A(n). Recall that if A is regular, then A(n) := An⊗KΣn, where An is the K-vector space of n-ary operations without permutations of the entries. We adopt Sweedler notation for binary cooperation ∆ on a K-vector space V and ...
