Macrophage-derived exosomes carrying RAD50 attenuate oxidative DNA damage and p53–p21-dependent S-phase arrest in spermatogenic cells
Occupational heat and blast overpressure impair spermatogenesis, and whether repair capacity supplied from outside the germ cell can lift the resulting block has not been tested. GC-2 spermatocytes received 1000 shock-wave pulses then 100°C for 40 s, and C57BL/6 mice received a 10% methane blast with intratesticular te...
