Figure 4. Magel2-null females display longer and irregular estrus cycles determined by vaginal cytology.

Figure 4

Representative examples of estrous cycling patterns from two individual female mice of each genotype are shown for each of the two ages tested. (A–B) 10 week old control females display regular 4–5 day cycles while 10 week old Magel-2 null females spend longer periods in estrus and diestrus, and experience fewer proestrus events (C–D). At 26 weeks of age, control females still display regular cycles (E–F) while Magel2-null animals have further deteriorated cycling patterns (G–H). The Y-axis represents estrus stage: E, Estrus; D, Diestrus; P, Proestrus.
