This confocal microscope image from a study in the Oct. 18 online edition of Cell Reports shows spermatocytes in mice deficient for a Fanconi anemia pathway protein, Fancd2. The study from Cincinnati Children’s Hospital Medical Center reports that mice lacking Fanconi anemia and DNA damage response proteins have disrupted sex chromosomes and are infertile, which the authors describe as a key finding in reproductive science.
