查询词典 nucleation

The amount of vimentin IF per cell was higher than those of tubulin and F-actin at 12-24h of culture, but it broken down and decreased steadily when the cells became differentiated into late erythroblast at 36-48h of culture, thus facilitated the eccentric nucleation which we regard it as the initial step of denucleation. Both of the fluorescence intensity of tubulin and actin exhibited a significant rise and aggregated between the extruding nucleus and incipient reticulocyte before and during denucleation, and finally play a role in the commitent to ennucleation, the second phase of denucleation.
