During early testicular development, neonatal gonocytes transform into spermatogonial stem cells (SSC), and any untransformed gonocytes are thought to undergo apoptosis. In human cryptorchidism, persisting gonocytes may lead to seminoma. Using Bcl2-associated X knockout (BAXKO) mice, we investigated apoptosis in gonocyte development during mouse minipuberty. Testes from BAXKO, heterozygous (HET), and wild-type (WT) littermates were collected on postnatal days 1, 3, 6, and 9 (n = 6/group), labelled with antibodies against mouse vasa homologue (MVH, germ cell marker) or promyelocytic leukaemia zinc-factor (PLZF, SSC marker) and imaged for cell counting. Total germ cells/tubule, i.e., the numbe..View full abstract
