How morphogen gradients yield precise patterning is an important question in #DevelopmentalBiology. New study investigates the impact of cell size in this context.

Impact of cell size on morphogen gradient precision
Tissue patterning during embryonic development is remarkably precise. We numerically determine the impact of the cell diameter, gradient length, and the morphogen source on the variability of morphogen gradients and show that the positional error increases with the gradient length relative to the size of the morphogen source, and with the square root of the cell diameter and the readout position. We provide theoretical explanations for these relationships, and show that they enable high patterning precision over developmental time for readouts that scale with expanding tissue domains, as observed in the
Drosophila
wing disc. Our analysis suggests that epithelial tissues generally achieve higher patterning precision with small cross-sectional cell areas. An extensive survey of measured apical cell areas shows that they are indeed small in developing tissues that are patterned by morphogen gradients. Enhanced precision may thus have led to the emergence of pseudostratification in epithelia, a phenomenon for which the evolutionary benefit had so far remained elusive.
Not only @ETH & @EPFL get hit hard with exploding student numbers, 🇨🇭federal budget woes, and limited access to 🇪🇺 @ERC_Research grants & networks.

W/ the spirit of St Jordi🐉, I read my favorite book (only 3 chaps, though).
"Scaling: Why is Animal Size so Important?" taught me animal size dictates many parameters, including time. Rather than real clock time, using physiological time helps understand animals comprehensively

Our paper is out! Xenopus embryos follow
#kleiber’s power law between metabolic rate and body mass. But triploids embryos which are made of fewer larger cells have a lower metabolic rate than diploids. 1/3
