FIG. 1.

Migrating GCs in the fetal testes express SSEA-1. (A) High-power (× 60 objective) magnification showing high levels of SSEA-1 expression in migrating GCs (M), weak SSEA-1 expression in partially compartmentalized GCs (P), and undetectable levels of SSEA-1 expression in GCs located within well-defined sex cords (C). Note mitotic figure (indicated by arrow) demonstrating proliferative activity of GCs within sex cord. (B) Medium-power (× 40 objective) magnification showing localization of SSEA-1 to GCs migrating within the extracordal space. Representative photomicrographs are shown.
