Oocyte Meiosis 01 icon.jpg A mouse oocyte undergoing spindle migration followed by first polar body extrusion and MII spindle positioning.
  • blue - Hoechst staining of chromosomes.
  • green - F-actin probe (UtrCH-GFP, utrophin calponin homology domain fused to GFP) label cortical changes during spindle migration.

The video shows that cytoplasmic streaming continues to the MII arrest stage to maintain the oocyte set of chromosomes/MII spindle in place close to the cortex.

Frames are 11 min apart, and video length is 840 min. Bar, 20 µm.
