Fig. 6. A sequence of eight time-lapse confocal photographs (time from 0' to 137' 20'') of an embryo carrying the transgenic insertions Tg(H2AF/Z)^kca37 and Tg(H2AF/Z)^kca66 to illustrate the migration of postmitotic cells to the subventricular region of the neural tube. The embryo is oriented a little obliquely, such that the two halves of the neural tube are not in register. One cell in metaphase is indicated by an arrow at 0'. After division at 12' (arrows indicate both daughter nuclei), one of the nuclei (left arrow) can be seen to move towards the subventricular region to join differentiating cells in the external region of the spinal cord.

Notice that the most external nuclei are separated from the others by a dark line, most probably corresponding to an incipient neuropil (at 12' and thereafter). Anterior is towards the left in all photographs.
