Transplantation of testis germinal cells into mouse seminiferous tubules. The film strip shows in sequence the technique for microinject ing cells using two procedures: rete testis and collecting duct injection. In the background un der the film strip are shown microscopic cross sections of mouse seminiferous tubules. From top to bottom on the left: the top panel shows normal mouse spermatogenesis, which is mostly obscu red by the film strip; in the second panel, seminiferous tubules of a busulfan-treated mouse us ed as a transplant recipient are shown. Note Sertoli cells on basement membrane and absence of germ cells; in the third frame are seen seminiferous tubules of a mutant Wv/Wv recipient mouse which contain only Sertoli cells and lack endogenous germ cells. From top to bottom on the righ t: first panel is a seminiferous tubule of a busulfan-treated recipient 110 days following tran splantation of transgenic testis cells that can be stained blue. The blue cells indicate that t he spermatogenesis is from transplanted transgenic donor cells; second panel on right is a semi niferous tubule showing spermatogenesis (blue cells) from donor spermatogonial stem cells that had been frozen, stored and then thawed before transplantation; third panel on right shows the edge of a seminiferous tubule of a recipient immunodeficient mouse into which transgenic rat te stis cells had been transplanted. The blue cells indicate the presence of rat spermatogenesis w hich produces normal rat spermatozoa that can be found in the mouse epididymis.
