If they proliferate down here, as I expect, commuters on the Staten Island ferry some morning will get close enough to a seal to notice water dripping off his whiskers, and — if he makes his alternative head-last drop-down into deeper water, as against a dive — watch the seal's nostrils, the final part of him, magically squeeze shut a quarter-second before he's gone.
In myoblast cell cultures Pax7 is similarly not expressed in differentiated myotubes, but is maintained in the smaller accompanying population of undifferentiated cells that stops proliferating, down regulates MyoD and returns to a non-proliferating state reminiscent of the quiescent satellite cell [10].
Antimicrobial conductive silver paint was applied to the underside of the cap to prevent microorganisms from proliferating down the sides of the vessel and contaminating the lungs (hence, the only proliferative pathway available was along the external surfaces of the ETT).
There is mounting evidence that the differentiation of stem cell descendants requires a lowering of their capacity to proliferate through down-regulation of growth related processes (Chia et al., 2008; Knoblich, 2010).
Northern blot analysis of miR-221/222 expression in QMb-ts cells confirmed that these miRNAs are highly expressed in proliferating myoblasts, down-regulated in differentiated myotubes and that their regulation is opposite to that of miR-133 (Fig. 2).
Investors have so far paid little attention to intangibles, but as write-downs proliferate they are likely to become increasingly wary of industries with a high ratio of goodwill to assets, such as health care, consumer goods and telecoms.In this section The ties that bind An Italian lifeline Looking Good?
As the notochord is being laid down, cells proliferate from each side of the primitive streak, forming the mesoderm, which spreads out laterally and, as a result of migration and multiplication of cells, soon comes to occupy most of the space between the ectoderm and the endoderm on each side of the notochord.
In other compositions the rings proliferate endlessly, tumbling down the canvas in disco pink and kinky Bentley black, round and bold as nightclub lights.
"As Linux has proliferated up and down the product supply chain, so has the complexity of managing compliance," said Jim Zemlin, executive director of The Linux Foundation.
Because of his leadership role, his negativity trickled down, proliferating an attitude that seriously damaged productivity.
As intervertebral space narrowed down, proliferating chordoblasts and denser packet chordocytes were revealed through toluidine blue staining and PCNA antibody binding, respectively.
