As the embryonic nuclei progress to metaphase, SUMO associates with the condensing chromosomes and appears to be concentrated in regions around the centromeres, as marked by the points of closest association between the spindle and the chromosomes (Figure 7C, left panels).
As techniques for culturing dissociated embryonic neurons progress, there is a need to develop methods to ascertain how well these cultures mirror the brain area from which they are derived.
These results underscore a sustained role of Bcd in the transcriptional decisions of its target genes as embryonic development progresses.
As embryonic development progresses however, the Z/AP and Z/EG transgenes become methylated, resulting in the eventual incorporation of the transgenic loci into heterochromatin, which inhibits access of transcription factors and Cre recombinase.
Then, as embryonic development progressed into the peri-implantation stages, aPKC began to accumulate centrally in the EPI together with F-actin.
Thus, cell number steadily increases as the embryonic development progresses through the peri-implantation stages marking the onset of cell proliferation and growth that follows the cleavage divisions of pre-implantation development.
Even though the study of biomimetic MOMs is still at its embryonic stage, considerable progress has been made in the past few years.
Yet despite the high hopes for embryonic stem cells, progress has been slow — so far there are no treatments with the cells.
by exploiting what was known about embryonic development and progress made with mouse ESCs [ 30].
Its neuronal localization is primarily at the plasma membrane of the soma in the embryonic brain and progresses into homogeneous expression in the postnatal rat brain.
These oocyte-like structures, in extended cultures, showed embryonic development and progressed through two-cell, four-cell, eight-cell, morula, and blastocyst-like structures, indicative of their developmental competence.
