germline cells
The Kai Laboratory will conclude its activities at Osaka University at the end of the current academic year and will be newly established in the Graduate School of Life Sciences, Kyoto University, starting in April 2026.
Prospective students and researchers interested in joining the laboratory are kindly requested to refer to the laboratory website at Kyoto University.
Research Theme
Although individual animals do die, the species are maintained by sexual reproduction which give rises to next generation. Individuals are just like vehicles in which passenger –genetic information– can ride to be inherited to next generation through germline lineage. As such, germline cells are the most important cells to maintain the species. Drosophila melanogaster is one of the ideal model organisms where we can study gametogenesis. How are germline stem cells maintained in the microenvironment, niche? What is the molecular mechanism that controls germline cells to mature into egg and sperm? How germline genomes are safely guarded by non-coding RNA from transposons attacks? Our group has been addressing such molecular mechanisms for better understanding of gametogenesis.
