Migrating melanoblasts exhibited an amoeboid-type motility, as described for migrating Dictyostelium cells (Insall and Machesky, 2009) and for leukocytes as they migrate towards a wound (Herbomel et al., 1999; Cvejic et al., 2008) (Fig. 2E-H; supplementary material Movie 3).
This paper analyzes the key steps in making India gradually migrate towards a cashless economy.
More and more Fortune 500 giants are starting to migrate towards a flexible, on-demand labor model (for the obvious reasons we documented above).
After the second world war however, several countries and their respective currencies, started to shift away from the gold standard and migrated towards a fiat currency system.
We also examined the ability of these E-cadherin depleted cells to migrate towards a gradient of FBS.
CCR9 is a candidate chemokine receptor for the regulation of this type of DC trafficking, because it has been demonstrated that CD11c-positive splenic DCs as well as peritoneal MΦ migrate towards a CCL25 chemotactic gradient [1].
Here again we found that acap-A−/B− cells migrated towards a point source of cAMP with no apparent change in speed or directionality compared with wild-type cells (Fig. 6B D and Videos S1, S2, S3, and S4).
We assume the modeled sprout is one of several sprouts separated by 100 µm (which is mathematically represented by a reflecting boundary at r = 50 µm) simultaneously migrating towards a distant VEGF source (e.g. tumor) (see Methods, Geometrical and Transport Parameters).
ECs migrate towards a higher concentration of anchored cell adhesion molecule, a phenomenon termed haptotaxis.
Clearly, ferritins with higher amounts of iron migrate towards a higher density zone of the gradient.
