This story is so cool. I love reading about this stuff. This is the future and it's gonna be awesome. In twenty more years, we'll be able to re-enact Blade Runner, in real life. Sweet. I love science.
Genetic Mingling Mixes Human, Animal Cells
http://news.yahoo.com/s/ap/20050430/ap_on_sc/human_animal_mixing_3&printer=1 "Few human-animal hybrids are as advanced as the sheep created by another stem cell scientist, Esmail Zanjani, and his team at the University of Nevada-Reno. They want to one day turn sheep into living factories for human organs and tissues and along the way create cutting-edge lab animals to more effectively test experimental drugs."
"Zanjani is most optimistic about the sheep that grow partially human livers after human stem cells are injected into them while they are still in the womb. Most of the adult sheep in his experiment contain about 10 percent human liver cells, though a few have as much as 40 percent, Zanjani said.
Because the human liver regenerates, the research raises the possibility of transplanting partial organs into people whose livers are failing."
"Years ago, the two applied for a patent for what they called a "humanzee," a hypothetical - but very possible - creation that was half human and chimp.
The U.S. Patent and Trademark Office finally denied their application this year, ruling that the proposed invention was too human: Constitutional prohibitions against slavery prevents the patenting of people. "
