Abstract

Morphogens keep it simple Concentration gradients of certain molecules termed 'morphogens' are known to control tissue development during embryogenesis. Yu et al. have addressed the little understood question of how such gradients form. They use an advanced and highly precise technology for imaging molecules in vivo (fluorescence correlation spectroscopy) to show that freely diffusing Fgf8 morphogen gradients in living zebrafish embryos arise from a simple source–sink mechanism.
