Germ-cell depletion and loss of spermatogonial stem cells in Mcm9Gt(XG743)Byg/Mcm9Gt(XG743)Byg males

mortality/aging
N
• viable

liver/biliary system
• increased incidence in males at 1 year of age and all affected mice have multiple hepatocellular carcinomas

reproductive system
N
• males and young females are fertile
• newborn mice have 82% fewer oocytes
• almost completely absent at 24 weeks of age
• some (about 5%) seminiferous tubules lack spermatogonia
• progressive germ cell depletion
• a 67% decrease in epididymal sperm concentration at 12 weeks of age
• despite the decrease in sperm concentration, males are fertile
• a 72% decrease of gonocytes in nascent seminiferous tubules
• decrease in the total number of follicles at 6 and 12 weeks of age
• nearly devoid of primordial follicles at 6 and 12 weeks of age
• some tubules show progressive germ cell depletion, lack spermatogonia or contain a cohort of spermatocytes arrested in meiosis
• detected at puberty and the difference in size compared to controls increases over time
• at 1 year of age
• about 5% of seminiferous tubules contain a cohort of spermatocytes arrested in meiosis

neoplasm
• all males develop tumors by 1 year of age
• at 1 year of age
• increased incidence in males at 1 year of age and all affected mice have multiple hepatocellular carcinomas

cellular
• newborn mice have 82% fewer oocytes
• almost completely absent at 24 weeks of age
• some (about 5%) seminiferous tubules lack spermatogonia
• progressive germ cell depletion
• a 67% decrease in epididymal sperm concentration at 12 weeks of age
• despite the decrease in sperm concentration, males are fertile
• a 72% decrease of gonocytes in nascent seminiferous tubules
• MEFs show a delay in progression from G0/G1 to S phase following release from serum starvation in the presence of aphidicolin
• increase in metaphase chromatid breaks

hematopoietic system
• circulating micronucleus levels are increased

endocrine/exocrine glands
• decrease in the total number of follicles at 6 and 12 weeks of age
• nearly devoid of primordial follicles at 6 and 12 weeks of age
• some tubules show progressive germ cell depletion, lack spermatogonia or contain a cohort of spermatocytes arrested in meiosis
• detected at puberty and the difference in size compared to controls increases over time
• at 1 year of age
