Therefore, a self-template with a conformally coated HsGDY layer would permit the migration of species from the inner self-template region through the HsGDY and into the external surface of the HsGDY layer where they can be designed to react with desirable species in bulk solution and vice versa.
Thus if interspecies hybridization contributed to the shared sequences, it likely would have occurred before or during periods of glaciation, when land bridges could have permitted the migration of macaques as far South as Indonesia.
Because relative reproductive rate (Equation 3) represents a limit for large numbers of generations and negligible frequencies of foreign incompatibility alleles, one might expect discrepancies to arise in cases with forward migration rates sufficiently high to permit the migration of an individual carrying a foreign incompatibility allele back into the other species.
According to Haq et al.[ 77], during the lower middle Miocene, sea levels were generally very high, but two sea-level drops of almost 100 m may have occurred between 17 and 15 Ma, which could have permitted the migration of fish from South to Central America.
Together, these observations suggest that radial glial scaffold can critically influence interneuronal migration and placement in the developing cerebral cortex by attracting, repulsing, stalling, or permitting the continued migration of distinct subsets of interneurons.
Our observations suggest local radial glial cells, by their potential ability to repulse, attract, stall, or permit the continued migration of distinct subsets of interneurons, may play an essential role in the targeting of appropriate subsets of interneurons into appropriate areal locations (Fig. 2, 3, Movies S1, S2).
The abnormalities of the glia limitans permitted the overextended migration of neurons in the developing brain, which is the most important diagnostic feature of cobblestone lissencephaly observed in the most severe cases of secondary dystroglycanopathy.
The application of this technique to intravenous-infused cells permits the time course of cell migration and the degree of cell homing to be measured in the live animal.
The Nazis not only permitted this migration; they facilitated it until the outbreak of the war, while the British, in the somewhat forlorn hope of winning Arab good will, imposed and enforced restrictions.
Beyond the effects of size exclusion on the invasive behavior of cells, our migration chip permitted the quantification of drastic differences in 2D and 3D migration speeds.
