In 12-week fetuses, c-KIT immunoreactivity is weak, but M2A immunoreactivity is consistently strong.
At 15 and 18 weeks of gestation, c-KIT immunoreactivity is found in most germ cells.
D2-40 is expressed in Sertoli cells as well as in germ cells, but is not expressed in ovarian follicles undergoing meiosis.
D2-40 is also reactive in fetal Sertoli cells, but its expression is consistently weaker than in germ cells.
