Outline of Final Research Achievements

All over the world, rare or endangered avian strains are becoming highly exposed to risks of epidemics, i.e., avian influenza.The most feasible ex situ management method of avian genetic resources is germline cells cryopreservation. In this study, the preservation of sperm, primoridial germ cells (PGC) and embryonic stem (ES) cells from the Onagadori (Japanese extremely long-tailed chicken breed: designated as a special natural treasure of Japan) were conducted.
In this study, the preservation of sperm, PGC and ES cells from the Onagadori was succeeded. This result suggested that sperm, PGC and ES cells will be the candidates as a conservation tool of rare or endangered avian strains.
