Fig. 3.
MARF1null eggs fail to complete meiosis. a Meiotic spindles show proper meiotic metaphase I arrest in control and MARF1null stage 14 oocytes. The percentages of normal oocytes with proper meiotic spindle are shown. The numbers of normal oocytes with proper meiotic spindle/the numbers of observed oocytes are shown in parenthesis. Scale bar is 5 μm. b Polar body shows completion of meiosis in control unfertilized eggs, but not in MARF1null unfertilized eggs. Neither meiotic spindle nor polar body were observed in MARF1null unfertilized eggs. The percentages of normal unfertilized eggs with a proper polar body are shown. The numbers of normal unfertilized eggs with a proper polar body/the numbers of observed unfertilized eggs are shown in parenthesis. Scale bar is 5 μm. DNA was stained with DAPI (blue) and alpha-Tubulin was visualized with FITC-conjugated anti-alpha-Tubulin antibody (green)
