Abnormalities observed during meiosis of Mer3 spermatocytes: a spermatid containing two nuclei of equal size (arrows) and two Nebenkerns (A), tripolar spindle in a spermatocyte going through the second meiotic division (B), and four-polar spindle in a spermatocyte undergoing the second meiotic division (C-E). Panel C shows the phase contrast image, panel D the DAPI-stained nuclei, and panel E the merged image. Arrow points to the central spindle midzone [29]. For comparison, wild-type meiotic cells in telophase were shown (F).
