News Alert: Scientists for the first time have created a part-human, part-pig embryo — raising the possibility of interspecies organ transplants
The experiment, described in the journal Cell, involves injecting human stem cells into the embryo of a pig, then implanting the embryo in the uterus of a sow and allowing it to grow. The work – using a technique that is already the subject of vigorous ethical debate – is a significant step toward the development of animal embryos with functioning human organs.
