title: BMP signalling: visualisation of the Sog protein gradient.
abstract: Extracellular inhibitors are commonly used in development to modulate the activities of signalling molecules. Direct visualisation in the Drosophila embryo of Sog, a Dpp/Scw inhibitor, has now revealed a graded distribution established by degradation and endocytosis.
