3.5 hr time-lapse movie of a stage 5HH chicken embryo in which the epiblast was labeled with nuclear red. Tracks of single-labeled nuclei are shown at three different AP levels of the PS to illustrate differences in longevity of the cells. Dorsal view (neuromesodermal progenitor [NMP]: gold; paraxial mesoderm precursor [PMP]/lateral plate progenitor [LPP]: green; extraembryonic mesoderm progenitor [EMP]: blue). t = 4 min. 20× objective, LSM 780.
