In hepatopancreatic cells of the diseased crab (Figure 2), condensation and margination of nuclear chromatin, disappearance and deformation of mitochondria cristae, and endoplasmic reticulum and lysosomes disintegration, and different size of vesicles could be observed Nuclear condensation, cell atrophy and intercellular space and a lot of spermatogonium with distinct nuclear pyknosis and vesicles could be observed in gonad of the diseased crabs the membrane of spermatogonium was thicken and rucked up (Figure 3).
However, in these species germ cell development is clonal, since each spermatogonium is surrounded by a single Sertoli cell in the seminiferous lobules; and thus a group of clonal germ cells arising from a single spermatogonium develops synchronously within the cyst (Schulz et al.
During normal development, neonatal gonocytes transform into adult dark spermatogonium at approximately six months of age (Hutson et al.
FGF8 is expressed during specific phases of rodent oocyte and spermatogonium development.
The most susceptible cells were actively dividing spermatogonium and spermatocytes up to preleptotene phase.
