Morpheus Unbound: Reimagining the Morphogen Gradient

The theory that the spatial organization of cell fate is orchestrated by gradients of diffusing molecules was a major contribution to 20 th century developmental biology. Although the existence of morphogens is no longer in doubt, studies on the formation and function of their gradients have yielded...

description The theory that the spatial organization of cell fate is orchestrated by gradients of diffusing molecules was a major contribution to 20 th century developmental biology. Although the existence of morphogens is no longer in doubt, studies on the formation and function of their gradients have yielded far more puzzles than answers. On close inspection, every morphogen gradient seems to use a rich array of regulatory mechanisms, suggesting that the tasks carried out by such systems are far more extensive than previously thought.
