After 24 h of culture at 37°C in 5% CO2, the fluorescent cells on the bottom side of the inserts (corresponding to migrating cells) were counted and the migration rate was calculated.
In the first 0.5 h, the migration rate was very high, and then down slowly.
In 2010 the average 5-year national migration rate was 4.15%.
Average scratch width was determined at three random areas, and migration rate was calculated as follows.
The temperature dependence of the boundary migration rate was measured and the migration activation energy determined.
The highest single-cell migration rate was observed with 150 mV mm−1 applied EF on patterned and planar surfaces.
Scratch wound test indicated that the cells migration rate was significantly higher (14.9 µm2/h, P < 0.05) in the treated versus (11 µm2/h) for control PDLFs.
It was found that the cell substrate interaction controlled the cell mobility, and the highest migration rate was achieved on the surfaces with appropriate adhesion force.
No unstable implants were noted; all implant fixation interfaces were classified as "stable bone ingrown," and the cup migration rate was zero.
We modeled fault propagations as migration of fault terminations, and its migration rate was given by 1/100 of the total dislocation shown in Table 2.
In addition, he had assumed that the uphill rate would be faster, where species need to move less than 100 meters to drop 0.5°C, but the uphill migration rate was slower, a finding the researchers can't explain.
