How can cells use information from neighboring cells to improve the spatial precision of morphogen patterns? 🤔
We show that cells can gain positional information by "talking" to their neighbors - how much depends critically on spatial correlations of the patterns.

pN force coupling via talin is ancient, conserved from amoebae to humans; signaling came later.

Talin force coupling underlies eukaryotic cell-substrate adhesion - Nature Communications
Talin is a well-known regulator of cell adhesion and intracellular force transmission in animals. Here, the authors demonstrate that talin’s mechanical function is evolutionarily conserved and already established in unicellular eukaryotes.
