DNA bead-induced Ectopic Polar Body

A 4D movie showing the DNA bead-induced ectopic polar body extrusion during meiosis II.

  • The DNA beads (shown in blue) were injected at 10 O'clock position.
  • Microtubules were labeled by microinjection of rhodamine conjugated tubulin.
  • Note that the DNA bead spindle underwent rotation from horizontal to vertical position and the DNA beads were kept in the eggs after ectopic polar body extrusion.
  • Maternal chromosomes are out of the z-sections.
