Time Lapse of GFP::POP-1
(requires Windows Media Player plugin)



Other formats: AVI Quicktime

This time-lapse movie shows confocal image stacks of med-1::GFP::POP-1 signal from the E2MS2 to E4MS8 stages. The sequence pauses at the following events:

  • Contrast enhancement to show higher cytoplasmic levels in MSp, Ep
  • Equal cytoplasmic signal in mitotic MS daughters
  • Asymmetry in MS granddaughters shortly after birth
  • Coalescence of anterior-specific puncta by mid-interphase
  • Reduction in anterior levels before mitosis
  • Asymmetry in E4 in early interphase
  • Symmetry in late interphase E4
