• seminiferous tubules show a mosaic pattern in which about half of the tubules are largely devoid of germ cells, apart from a ring of spermatogonia adjacent to the basal membrane, and the remaining tubules show maturation arrest at the pachytene stage of spermatogenesis

• MEFs accumulate chromosomal rearrangements in response to genotoxic stress induced by mitomycin C
• MEFs are hypersensitive to the DNA inter-strand crosslinking agent mitomycin C and the PARP inhibitor olaparib, indicating hypersensitivity to genotoxic agents
• however, MEFs show normal response to ionizing radiation
