FIG. 6.

Compartmentalization induces cycling of GCs within fetal testes. Shown are representative photomicrographs of fetal testes after Ki67 staining. (A) Medium-power magnification (× 40 objective) shows quiescent GCs migrating through the internal rete testes (G), GCs beginning to cycle with the initiation of compartmentalization within partially formed sex cords (P), and GCs expanding within well-defined complete sex cords (C). (B) Medium-power magnification (× 40 objective) shows proliferating PGCs within sex cords and quiescent GCs within the extracordal space at all gestational ages. Note the similarity of signal distribution in comparison with Fig. 4.
