The degree of this reaction depends on the stage of the seminiferous cycle. Twelve stages of the seminiferous epithelium cycle were characterized. It first appears at day 4 after birth and migrates towards the periphery of the seminiferous cords. The testis comprises a seminiferous epithelium in which germ cells advance from the periphery to the lumen.

There were also the seminiferous tubules from which the spermatogenic cells had dropped out. We counted the number of each of the spermatogenic cell stages in a seminiferous tubule. Following a pressure increase in the pipette, the cell suspension was transferred to seminiferous tubules (dark blue). Some cells with a morphology very similar to macrophages were found in the epithelium of seminiferous tubules of immunodeficient mice. Re-examination of spermatogonial renewal in the rat by means of seminiferous tubules mounted 'in toto'. Variation in the sensitivity of the mouse spermatogonial stem cell population to fission neutron irradiation during the cycle of the seminiferous epithelium. Meiosis and spermiogenesis form a continuous gradient that extends from the periphery of the seminiferous tubule to the lumen where the mature spermatozoa are deposited. The diameter of the seminiferous tubules increased during culture. Spermatogenesis is a process of division and differentiation by which spermatozoa are produced in seminiferous tubules. However, the inner structure of the seminiferous tubules was maintained, and did not change relative to that before freezing. On the other hand, when we froze immature testicular tissue, many fragments had spermatogenic cells in the seminiferous tubules as they did before freezing. In addition, after cutting the tunica albuginea, a small piece of testicular tissue, including seminiferous tubule, was excised. The germ cells were injected into mouse testicular seminiferous tubules using a microneedle (40 m inner diameter) on a 10 ml syringe. Isolated seminiferous tubule subjected to reverse fibrin zymography using human urokinase and human plasminogen in the overlay mixture. These examples are from corpora and from sources on the web.
