Nuclear migration in unc-83(e1408);klc-2::KASH hyp7 precursors. (A) DIC images from a representative time-lapse sequence of unc-83(e1408);klc-2::KASH nuclear migration events. t = 0 min when the tip of cell 12 reached the opposite seam cell boundary. Anterior is to the left. (A’) Cell borders are outlined in black, nuclei migrating left to right are purple, and nuclei migrating right to left are green. Hyp7 cells are numbered 9–16, beginning with the posterior pointer cells. Bar, 10 µm.
