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
