Cryopreservation of Avian Germline Cells and Subsequent Production of Viable Offspring

Abstract

Cryopreservation of avian genetic material has become possible by preserving blastodermal cells or primordial germ cells. These germline cells can give rise to viable offspring via germline chimaeras. Cryopreservation of poultry semen is already possible. Thus, it is technically possible to preserve both male and female genetic material in liquid nitrogen and subsequently produce viable offspring in chickens. Proliferation of endangered avian species via germline chimaeras could increase genetic diversity. Development of new technologies such as nuclear transfer techniques in avian species is currently anticipated. © 2003, Japan Poultry Science Association. All rights reserved.
