morphogens

As Lawrence so eloquently described, individual cells recognize their positional coordinates through the activities of complex proteins called morphogens that form highly specified concentration gradients across the embryo.

The problem is that there is absolutely no reason to think that's how those patterns actually form; no one has identified even a single pair of Turing morphogens, despite decades of searching.

We introduce morphogens -- diffusible signal molecules -- and adhesive proteins (both molecular components of our DPMs) or we knock these molecules down.

The Origin of Form Was Abrupt Not Gradual 2008

I read and thought and discussed, and finally decided as a postdoctoral project to score for mutations affecting the informational content of the egg cell, with the aim of using them to isolate and identify morphogens in injection assays, in which the rescue of a mutant phenotype was indicative of the presence of an activity lacking in the mutant embryo, possibly the gene product.

A principal mechanism by which spatial complexity is increased is based on concentration gradients of morphogens, molecules that elicit different responses at different concentrations.

Activins are members of the important transforming growth factor beta TGF-beta family of "morphogens," i.e. developmental factors that direct and control the differentiation and eventual fate of early precursor cells.

During development, the body uses differing concentrations of morphogens, similar to activin, to direct precursors to become the various mature cells discussed above.

The mechanism that determines the ultimate size of a plant organ remains an active area of research, and insight is likely to be gained through future application of these strategies to mutants affecting organ size such as wing disk development, morphogens and mechanics play a role in controlling organ size

Retinoic acid (RA) is one of the most important morphogens involved in striatal neurogenesis, and regulates Nolz1 expression in different systems.
