In cultured chicken embryo neural tube segments, treatment with the anticonvulsant VPA not only decreased the number of migrating NC cells, but the treatment also changed the type of NC cell migration from individually migrating cells to migration as an epithelial sheet.
By quantifying the migration of more than 1800 individually marked fish, we showed that actual migration patterns followed predictions with a remarkable accuracy, suggesting that migration patterns have evolved in response to seasonally fluctuating trade-offs between predator avoidance and foraging gains.
Our data similarly suggest that fish in the Victoria and Daly rivers move rapidly into fresh water, although the precise timing of this migration appears individually variable.
The Role of Physical Cues in Collective Cell Invasion – This project will examine how the physical forces exerted upon cancer cells when they are confined within a tumor can affect the migration of these cells, both collectively and individually.
To analyze their respective role in the migration of immature DCs, we silenced them individually using shRNA-encoded lentivirus.
Tumor cells may migrate in bulk as clusters, strands, or sheets (collective migration) or individually.
To test for asymmetry in gene flow, we estimated full models, θ (4 N e μ or N f μ, composite measure of effective population size and mutation rate), and all pairwise migration parameters individually from the data and compared them to a restricted island model for which θ was averaged and pairwise migration parameters were symmetrical between populations.
I've never had an exhibition of individually framed photos.
On the basis of resightings of individually marked birds throughout the year between 2005 and 2012, we show that summer, autumn and winter survival were very high and independent of migration distance, whereas mortality during spring migration was much higher (18%) for the birds that wintered in Mauritania, compared with those flying only as far as France (5%) or Iberia (6%).
