Animal Breeding and Genetics


We are mainly working in the research fields of
1) QTL analysis for economic traits of chickens
2) phylogenetic analysis for chicken breeds
3) analysis for mutations in chickens and quail
4) preservarion of bioresources in chickens and quail (Tsudzuki, M.)
5) Molecular phylogenetic study based on genome and gene function of animals and birds (Nishibori, M.)
6) Establishment of biotechnologies that are robustly available across the animal species to apply for the genetic resource preservation at a cellular level as well as for the human infertility clinic.
At present, we are tackling the preservation of fertility as well as efficient production of sperm and eggs from surrogate parents through the development and improvement of techniques for the manipulation of germline stem cells including culture, cryopreservation and transplantation in birds and mammals.
