| Outline of Final Research Achievements |
Self-renewal of spermatogonial stem cells is central in mammalian spermatogenesis. Although many genes, which are necessary for normal functions of spermatogonial stem cells, have veen identified, transcriptional regulation remained unclear. In this study, the functions of Myc family genes, the transcription factors which stimulate proliferation of stem cells in other tissues, were examined. As expected, Myc genes were found to be necessary for normal proliferation of cultured spermatogonial stem cells and for normal spermatogenesis in vivo. These results indicate that Myc overexpression may improve the proliferation of cultured spermatogonial stem cells in other animals and that ablation of Myc genes can cause male infertility.
