Summary

edit
Description
English: Development of an individually cultured neuroectodermal progenitor cell. Time-lapse movie showing the development of a cultured progenitor cell that originated from the most ventral domain of the neuroectoderm. The generation of the first two ganglion mother cells (GMC1 and GMC2) by asymmetric divisions of the neuroblast and the symmetric division of GMC1 (taking place after GMC2 is born) into two postmitotic progeny cells (P) are indicated in the film. Assignment of further divisions is difficult due to the dense, three-dimensional arrangement of progeny cells. Note that during maturation of the clone (after approximately 23:15) a prominent pair of equally sized cells (which seem to be the two progeny of GMC1) moves a short distance apart from the cell cluster (along a fibre bundle) to later join the cluster again. Real time is indicated at the bottom. Selected frames and a schematic of the early divisions are shown in Figure 3.
