Abstract
The present study was conducted to apply an interspecies
germ cell transfer technique to wild bird reproduction. Pheasant
(Phasianus colchicus) primordial germ cells (PGCs) retrieved
from the gonads of 7-day-old embryos were transferred to the
bloodstream of 2.5-day-old chicken (Gallus gallus) embryos.
Pheasant-to-chicken germline chimeras hatched from the
recipient embryos, and 10 pheasants were derived from testcross
reproduction of the male chimeras with female pheasants.
Gonadal migration of the transferred PGCs, their involvement in
spermatogenesis, and production of chimeric semen were
confirmed. The phenotype of pheasant progenies derived from
the interspecies transfer was identical to that of wild pheasants.
The average efficiency of reproduction estimated from the
percentage of pheasants to total progenies was 17.5%. In
conclusion, interspecies germ cell transfer into a developing
embryo can be used for wild bird reproduction, and this
reproductive technology may be applicable in conserving
endangered bird species.
