Analysis of xenotransplanted mice testes one-month after transplantation using a buffalo gonocytes spermatogonia-specific marker, Dolichos biflorus agglutinin (DBA)..png

(A) DBA stained gonocytes/spermatogonia (arrows) that colonized the basal membrane of the recipient testis. Note that a few uncolonized DBA-positive gonocytes/spermatogonia are seen in lumen of seminiferous tubules (arrowheads). (B) No DBA-positive cells are visible in the contralateral testis section. Scale bar = 50 µm.
