Rat blood–testis barrier
A model depicting the migration of developing preleptotene spermatocytes across the blood–testis barrier (BTB}.
Migration during the seminiferous epithelial cycle of spermatogenesis utilizing the protein complexes of JAM/CTX and nectins at the Sertoli–germ cell interface.
(a) Movement of developing germ cells in the seminiferous epithelium of the adult testis. Germ cells first have to break through the image - tight junctions at the BTB with minimal disruptions. After the opening of the BTB, the progression of germ cells relies solely on series of transient adherens junctions at the Sertoli–germ cell interface. Assembly and disassembly of junctional complexes at the basal and apical ectoplasmic specialization occurs continuously.
