Salmon give birth to trout

The Guardian
Scientists in Japan have produced a baby trout born to a salmon. In
this week's Nature, Yataka Takeuchi and colleagues from Tokyo
University of Marine Science and Technology in Japan, announce their
successful transplantation of primordial germ cells (PGCs) from
rainbow trout embryos to East Asian masu salmon embryos to produce a
rainbow trout. The salmon had the ability to produce trout sperm and
eggs, enabling them to give birth to trout. It represents the first
time that donor PGCs have developed into functional sex cells in a
different animal.

The Salmon/Trout thing has NOTHING to do with ring species. We already knew
that organ transplants were possible across species. With the implant of
PGCs, they essentially transplanted sex organs. I do not see anything
revolutionary here.

Yes, the "subject" line of Maff's post was oddly lacking in
connection to the text. His Google links that follow do however
search for ring species-related links.

No, but it could become a useful technique for breeding
endangered species in captivity.

Thanks, Klaus. I was wondering where the 'ring species' tie-in was.

"Born"?

"Give birth to"?
Someone needs to inform this journalist that salmon and trout are
egg-layers with external ferilization. There are various live-bearing
groups of fishes, but salmonids are not among them.
Still, interesting story. The next step might be to have common
black bears produce lots of baby giant pandas...
It represents the first
time that donor PGCs have developed into functional sex cells in a
different animal.

Yeah, but it's still a fish.
