Schematic representation of our sampling design throughout gonocyte perinatal development in the rat. Rat testes were collected at four stages of development in vivo (solid red boxes) or at three time points after culture (dashed red boxes). For organ culture, testes were collected at 16.5 and 18.5 dpc and cultured for 4 and 3 days, respectively. ¹Rose et al. [7]
