diffusible

Large colonies will be observed along with a brown diffusible pigment within 2-4 days.

This diffusible factor was later shown to be Sonic hedgehog.

"If this gas is so highly diffusible..." Stone gave a slight smile.

Another central idea is that some gene products function as switches whereas others act as diffusible signals.

Plasmodesmata usually only allow the passage of small diffusible molecules, such as various metabolites.

Thus was born the notion of the morphogen, the diffusible conductor of cell fates.

He supposes that, in each abdominal segment, there is a gradient of some diffusible substance, from high at the front to low at the back.

Nitric oxide is a small highly diffusible gas and a ubiquitous bioactive molecule.

Calcium participates in an intracellular signalling system by acting as a diffusible second messenger to the initial stimuli.

These discoveries offer further evidence for the induction of fungal genes by diffusible elicitors present in the soil.

This result demonstrated that mitotic entry was controlled by a diffusible cytoplasmic factor and not by a "nuclear clock."

These signals, called guidance cues, can be fixed in place or diffusible; they can attract or repel axons.

Complex food substances that are taken by animals and humans must be broken down into simple, soluble, and diffusible substances before they can be absorbed.

Human shugoshin is diffusible and mediates formation of kinetochore-microtubules during bipolar spindle assembly.

The species also produces a diffusible yellow-green or red-violet pigment which fluoresces bluish-white under UV light.

Kellaway (1933), stated that P. textilis venom possessed a strong, highly diffusible coagulation factor.

Nodes that are depicted as lying along vertical lines are associated with the cell/environment interfaces, while the others are free-floating and diffusible.

Therefore, gene therapy could be a single treatment appealing, viral vectors used in the therapy are diffusible and capable to do transduction of the striatum.

Digit 2 is specified by a long-range diffusible form of Shh and Digit 1 does not require Shh.

Nodal and Wnt activity is antagonized in the endoderm which results in diffusible signals from Cerberus.

This gene codes for a protein (or microRNA or other diffusible molecule) that will be used in the regulation of another target gene.

In contrast, trans-regulatory elements are diffusible factors, usually proteins, that may modify the expression of genes distant from the gene that was originally transcribed to create them.

The N-terminal peptide, also known as diffusible survival evasion peptide, promotes neural cell survival under conditions of severe oxidative stress.

To conduct such a screen, isolates of many different microorganisms are cultured and then tested for production of diffusible products that inhibit the growth of test organisms.

The alternative view is that calcium is the diffusible messenger that enhances its own release through the process of CICR (Fig. 4).
