The Drosophila fly brings to light the role of morphogens in limb growth

Posted by on July 5th, 2017

• Scientists at IRB Barcelona clarify the function of the genes that drive wing development in the fruit fly Drosophila melanogaster. • Published in the journal eLife, this study unveils that the Dpp morphogen is necessary for wing growth but that its gradient does not govern this process. • Understanding the development of limbs in[…]

Spatial range of a morphogen gradient

Posted by on November 23rd, 2011

Estimating the range of a morphogen gradient Morphogen gradient, defined as a concentration field of a chemical factor that acts as a dose-dependent regulator of cell differentiation, is an established concept in developmental biology. However, morphogen gradients in real systems are difficult to measure and mechanisms by which they control patterns of cell fates are[…]
