DiI labelling in HH8 embryos reveals behaviour and trajectories of cells from the primitive streak.

(A, B, C) Long-term time-lapse imaging of embryos labelled in Hensen's node (A), the anterior (B) or posterior primitive streak (C) with DiI. Embryos were imaged for 20 hours and still pictures are shown at intervals of 2.5 hours. (D, E, F) Transverse sections of embryos labelled in Hensen's node (D), anterior (E) or posterior streak (F). (G) Summary of cell fates. Red represents Hensen's node and notochord (nc), green represents anterior primitive streak cells and paraxial mesoderm (pm) and blue represents posterior primitive streak cells and lateral plate mesoderm (lpm). n, node; nc, notochord; pm, paraxial mesoderm; s, somites. In (A) asterisks indicate the position of the node which regresses during axis extension. In (A, B, C) arrows show the most recently formed somite and arrowheads in (B, C) indicate the position of the most anterior DiI-labelled cells.
