Host: Alfonso Martinez Arias

Extracellular signals pattern tissues by instructing cells to acquire specific fates during embryogenesis. The spatial range of signals must adjust to the size of the embryo, because small and large embryos give rise to proportionately patterned adults, but it has remained unclear how this is achieved during early vertebrate development. I will present our recent quantitative experiments and mathematical modeling of scale-invariant patterning, revealing a novel mechanism that controls the spatial range of patterning signals in differently sized vertebrate embryos.
