However, this technique is still available only to mice and rats. Recently, xenoectopic transplantation of testicular cells into the subcutis of immunodeficient mice has been developed as a novel technology to rebuild seminiferous tubules and to produce functional sperm. In order to develop an alternative technology for transgenesis and induction of spermatogenesis in domestic animals, we examinedxenoectopic transplantation of bovine testicular cells. Testicular cells from neonatal(within 7 days)and juvenile(3-5 months)bovine and neonatal(within 7 days)mouse testes were prepared at the concentration of 1-5 x 10^7/ml(mouse)or 1 x 10^8/ml(bovine)and then mixed with equal volume of BD Matrigel^ Basement Membrane Matrix(Matrigel). The testicular cell/Matrigel suspensions were grafted into the subcutis of castrated immunodeficient male mice(BALB/c Slc-nu/nu). Morphogenesis of the grafts was examined between 1 and 44 weeks after transplantation. To examine the growth and differentiation of donor germ cells, the expression of VASA, which is expressed from gonocytes to early meiotic stages in mammalian male germ cells, was examined by immunohistochemistry. Grafts derived from mouse testicular cells regenerated complete functional seminiferous tubules 20 weeks after transplantation in which haploid spermatids were generated in the lumen. Initiation of reconstruction of seminiferous tubules from bovine testicular cells was also observed 10 weeks after transplantation. However, immunohistochemical analysis demonstrated that bovine germ cells failed to colonize along the basement membrane of reconstructed seminiferous tubules and to proliferate thereafter. Although further investigation for suitable conditions of bovine germ cell colonization and survival in the reconstructed seminiferous tubules is needed, xenoectopic transplantation would make possible to induce bovine spermatogenesis and be usefull for animal sciences, conservation of wild animals and male infertility.","subitem_description_type":"Abstract"}]},"item_2_description_41":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_2_publisher_14":{"attribute_name":"出版者
