... of the morphogens in the positional information model ( Kondo and Miura, 2010 ). Roughly speaking, the positional information model can be said to be the one in which the interaction between the factors in the reaction-diffusion equation is omitted. Conversely, adding the interaction between morphogens to the usual...

...Shari Carmon; Felix Jonas; Naama Barkai; Eyal D. Schejter; Ben-Zion Shilo ABSTRACT Morphogen gradients are known to subdivide a naive cell field into distinct zones of gene expression. Here, we examine whether morphogens can also induce a graded response within such domains. To this end, we explore...

One mechanism by which morphogens are proposed to traverse extracellular space is by traveling along specialized filopodia called...

Here, we measured the signaling dynamics of the morphogen Dpp, one of several Drosophila factors controlling morphogenetic growth...
