Research Summary

Hiroki Shibuya

Even though organisms reach the end of their lives at the individual level, they can survive semi-permanently at the species level by refreshing the genetic and epigenetic information in their germ cells and passing it on to the next generation. In order to ensure these processes, germ cells undergo a unique cell division called meiosis, which halves the number of chromosomes, and then undergo differentiation into sperm and eggs (gametes). Our team combines mouse and nematode genetics, cytology, and biochemistry to study the molecular basis of gametogenesis. In particular, we focus on the role of spermatid centrosomes in prophase I chromosome movement, homologous recombination, chromosome segregation, and flagellum formation.
