♀ | phenotype observed in females |

N | normal phenotype |
• lack spermatogonia
|
• lack of primordial germ cells by E14.5 (early germ cell marker Mvh absent)
|
• primordial germ cells migrate to genital ridge but fail to proliferate normally between 11.5 and 14.5 dpc
|
• significantly smaller testes at 6 wks of age
|
• no sign of spermatogenesis detected at 2 wks of age, due to spermatogonia cell depletion
|
• absence of spermatids in seminiferous tubules
|
• absence of spermatocytes in seminiferous tubules
|
• both sexes are sterile
|
• absence of spermatids in seminiferous tubules
|
• absence of spermatocytes in seminiferous tubules
|
• lack spermatogonia
|
• lack of primordial germ cells by E14.5 (early germ cell marker Mvh absent)
|
• abnormal centrosome number (>2) in some mutant PGCs at 13.5 dpc
|
• abnormal centrosome number (>2) in some mutant PGCs at 13.5 dpc
|
• abnormal metaphase configuration of mutant PGCs at 13.5 dpc
• precocious sister chromatid separation and arrest of PGCs in mitosis due to spindle checkpoint activation
|
• significantly higher mitotic indices in mutant PGCs than controls at 12.5, 13.5, and 14.5 dpc
|
• primordial germ cells migrate to genital ridge but fail to proliferate normally between 11.5 and 14.5 dpc
|
• higher levels of activated caspase-3, p53, and Bax in extracts of 13.5 dpc mutant genital ridges than in controls, suggesting p53-related apoptosis of mutant PGCs
|
• significantly smaller testes at 6 wks of age
