Figure 4. Sororin distribution during the meiotic divisions.

• A–J
  Double‐immunolabeling of Sororin (green) and SYCP3 (red), and counterstaining of the chromatin with DAPI (blue) on spread spermatocytes at (A) metaphase I (M I), (G) anaphase I (A I), (H) interkinesis (Int.), (I) prophase II (Pro. II), and (J) metaphase II (M II). The sex bivalent (XY) is indicated. Arrows indicate the centriolar area at cell poles. Selected metaphase I autosomal (B, C) and sex (E, F) bivalents.
• K, L
  Enlarged metaphase II centromeres.

Data information: Arrowheads indicate the Sororin labeling at the centromere of Y chromosome. The sex chromosomes (X, Y) are indicated. Scale bar: 10 μm.
