In such cases, the positive feedback loop that normally stabilizes the front in one aspect of the migrating cell is not present, affecting cell polarity and the features of migration in the direction of the chemokine source.
We also use detailed migration histories to examine whether fertility differs by features of migration.
It is argued that the pre-existing conceptions of citizenship and the specific features of migration interact to shape the trajectories of emigrant quasi-citizenship.
Far from being a novel development, "counterstream migration" is a prominent feature of migration in general, said Charles F. Longino, Jr., a gerontologist who in 1984 first documented the phenomenon of retirees moving from Florida to New York, using 1980 census data.
But Amanda Peck, a spokeswoman for University Settlement, which has been serving newcomers to the Lower East Side since 1886, said that while family separations are a feature of migration in many ethnic groups, the satellite-baby phenomenon seems rare outside the Chinese community.
Many of the features of the migration closely resemble diffusion-induced grain-boundary migration but some important differences are identified.
However, other features of this migration wave are likely to be shared by other immigrant-receiving countries.
This study allowed us to identify the principal features of the migration of doctors between Britain and France.
Several new features of RIN migration in the zebrafish have been captured in our time-lapse movies (Fig. 10).
Nonetheless, this observation further supports the utility of the CIA assay for studying features of cell migration and invasion that other assays do not cover.
One of the main features of tangential migration of interneurons is the discontinuous translocation of their nucleus toward the centrosome, a process termed nucleokinesis (Bellion et al., 2005, Schaar and McConnell, 2005).
