mortality/aging
• about 25% of mice die between E13.5 and E14.5 and another 25% die between E16.5 and E19.5
• all mice that survive until birth die within 48 hours

respiratory system
• pups isolated at E19.5 fail to inflate their lungs despite visible breathing efforts

cellular
• MEFs proliferate slower and produce smaller colonies
• Cre mediated recombination of the floxed allele produced a decrease in colony number and size and stopped proliferation by blocking cytokinesis

homeostasis/metabolism
• live born pups appear cyanotic

integument
• live born pups appear pale

reproductive system
• oocytes rarely grow larger than 50 um in diameter, indicating arrested oocyte growth
• oocyte-specific expression of Gdf9 and Bmp15 is nearly undetectable
• oocytes exhibit altered levels of several oocyte-specific factors, including Pou5f1, Figla, Lhx8, Oosp1, and Sohlh2
• secondary follicles often contain a degenerating oocyte
• no mature follicles are observed
• percent of follicles in the primary stage is significantly higher than in controls (83% versus 20%)
• no multilayered, antral follicles or Graafian follicles are observed
• ovarian follicle maturation is halted; no post-secondary follicles are observed
• however, no differences are observed in the number of primordial follicles
• some secondary follicles exhibit an irregular/incomplete second layer of granulosa cells and often contain a degenerating oocyte
• percent of follicles in the secondary stage is significantly lower than in controls (17% versus 45%)
• adult females show a ~30% reduction in ovary size relative to control females
• in whole ovaries, mRNA levels of Gdf9 and Bmp15 are nearly undetectable, whereas mRNA levels of Bmp6, Kit, and Kitl are significantly increased relative to control ovaries
• although vaginal cytology indicates estrus stage changes, no regular cycle or periodicity is observed during a 3-wk test period indicating failure of estrus cycling
• when placed individually with wild-type males, 6-wk-old females never appeared pregnant or produced offspring

homeostasis/metabolism
• serum inhibin-A levels are decreased or undetectable in all females examined, regardless of staging by vaginal cytology
• serum FSH levels are dramatically increased in females, regardless of staging by vaginal cytology

behavior/neurological
• vaginal plugs are infrequently detected during a 5-mo breeding trial

cellular
• oocytes rarely grow larger than 50 um in diameter, indicating arrested oocyte growth
• oocyte-specific expression of Gdf9 and Bmp15 is nearly undetectable
• oocytes exhibit altered levels of several oocyte-specific factors, including Pou5f1, Figla, Lhx8, Oosp1, and Sohlh2
• secondary follicles often contain a degenerating oocyte

endocrine/exocrine glands
• no mature follicles are observed
• percent of follicles in the primary stage is significantly higher than in controls (83% versus 20%)
• no multilayered, antral follicles or Graafian follicles are observed
• ovarian follicle maturation is halted; no post-secondary follicles are observed
• however, no differences are observed in the number of primordial follicles
• some secondary follicles exhibit an irregular/incomplete second layer of granulosa cells and often contain a degenerating oocyte
• percent of follicles in the secondary stage is significantly lower than in controls (17% versus 45%)
• adult females show a ~30% reduction in ovary size relative to control females
• in whole ovaries, mRNA levels of Gdf9 and Bmp15 are nearly undetectable, whereas mRNA levels of Bmp6, Kit, and Kitl are significantly increased relative to control ovaries
