| Outline of Final Research Achievements |
It is well established that long-term spermatogenesis in mammals is supported by spermatogonial stem cells (SSCs). However, the molecular mechanisms governing SSC maintenance and differentiation is poorly understood. This study focused on dynamic changes in nuclear structure and epigenetic status that occur during SSC differentiation. These changes are important for gene expression programs and hence may greatly contribute to the conversion of cellular characteristics as SSCs differentiate. To identify the epigenetic changes in more detail, SSCs and progenitor cells were sorted and the global epigenetic status of each cell population was analyzed.
