FGF morphogen gradient self-generates a recipient tissue-specific contour by feedback-regulating its cytoneme-mediated dispersion.

Diffusivity, extracellular interactions of Nodal ligands with the receptors and inhibitors, and selective ligand destruction collectively shape the Nodal morphogen gradient.

A kinetic model of morphogen interpretation is more suitable than classic threshold or ratchet models to understand how a signal gradient generates different target gene expression patterns.

Statistical analysis of morphogen gradients indicates that non-linear morphogen decay does not lead to significantly increased patterning precision, and in fact, the opposite is observed far from the source.

Photoreceptors diversify their target field at long range through a graded signal.

Distinct metabolic states coupled with differing morphogen levels regulate HC morphology along the tonotopic axis of the developing chick auditory organ.

The morphogen profiles that pattern the fruit fly attain desired levels of spatial precision in a cost-effective manner.

Direct interaction between Hedgehog-sending and Hedgehog-receiving cytonemes is a fundamental mechanism for morphogen transfer and gradient establishment.

Theoretical and experimental evidence that Hh signaling dynamics balances robust positioning and sharpness of different target genes in the Drosophila wing disc.

The body axis of insects is divided into different fates using a self-regulatory and threshold-free mechanism.
