As reproductive tissues age, DNA repair mechanisms become less efficient, causing genomic damage to accumulate.
Collective cell migration relies on a directional signal that comes from the moving cluster, rather than from external cues.
Watch the cell transplant experiments in zebrafish that suggest certain embryonic cells rely on intrinsic directional cues for collective migration.
