Fig. 9. Asymmetric mitoses of primary nf and ns blast cells: spindle dynamics.
Time-lapse fluorescence video micrographs of primary blast cells (cl.ag. 40-45
hours) descended from an N teloblast injected with tau::GFP mRNA. The elapsed
time (minutes) is indicated in the top right-hand corner of each panel. (A)
Dividing ns cell. (B) Dividing nf cell. (C) A fortuitous specimen in which an
ns and a younger nf cell (separated by a two-cell nf clone and an undivided ns
cell) were dividing simultaneously. Broken outlines indicate the cell borders;
arrows indicate the spindle midbody. Scale bar: 10 µm.
