Cover legend

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. For details see "Transplantation of testis germinal cells into mouse seminiferous tubules" by Ogawa et al. in this issue.
