Outline of Final Research Achievements |
The mouse spermatogonial stem cell population is composed of two functionally distinct subpopulations and these subpopulations form hierarchal relationship. To reveal molecular basis controlling this hierarchy, we identified several genes specifically expressed in these populations from transcriptome analysis. Through the functional screening, we selected candidate genes and found one of the genes regulating transcriptional network to maintain undifferentiated state in cultured spermatogonial stem cells. We did not find the obvious phenotype in conditional knockout mice, and thus further analysis is needed to unveil the role.
