Pattern formation by a moving morphogen source.
During Drosophila melanogaster oogenesis, the follicular epithelium that envelops the germline cyst gives rise to an elaborate eggshell, which houses the future embryo and mediates its interaction with the environment. A prominent feature of the eggshell is a pair of dorsal appendages, which are needed for embryo respiration. Morphogenesis of this structure depends on broad, a zinc-finger trans...

متن کاملAggregation of a Distributed Source in Morphogen Gradient Formation.
In the development of a biological entity, ligands (such as Decapentaplegic (Dpp) along the anterior-posterior axis of the Drosophila wing imaginal disc) are synthesized at a localized source and transported away from the source for binding with cell surface receptors to form concentration gradients of ligand-receptor complexes for cell signaling. Generally speaking, activities such as diffusio...
متن کاملMorphogen gradient formation.
How morphogen gradients are formed in target tissues is a key question for understanding the mechanisms of morphological patterning. Here, we review different mechanisms of morphogen gradient formation from theoretical and experimental points of view. First, a simple, comprehensive overview of the underlying biophysical principles of several mechanisms of gradient formation is provided. We then...
متن کاملFormation of a Morphogen Gradient: Acceleration by Degradation
I is known that several classes of signaling molecules stimulate complex concentration-dependent responses that are critical for growth, development, and tissue formation in multicellular organisms. 4,11 In recent years there have been many quantitative studies that revealed important features and details of morphogen gradients in different biological systems. 10 However, fundamental mechanisms...
