For the first time, the government of japan approves a research study for human-animal embryos, which doesn’t mean that real-life creatures will be made like mermaids and not in too in future also it will be done this is just done to grow on-demand human transplant by animal surrogates.
Japanese Stem cell scientist Hiromitsu Nakauchi got approval from the government for the first human-animal embryos experiment, Nakuchi is the director of Stem Cell biology and regenerative medicine at Tokyo University and team lead at Stanford’s Nakuchi lab.
The first test is underway to grow human cells in rat and mouse embryos before transplanting the embryos into a surrogate animal, the end goal of this experiment is to create animals whose organs are build from human cells that can be used to fulfill the long large demand of organ donation.
Nakuchi had already performed a test achieving success with a non-human animal hybrid, In 2017 he worked in an experiment where he injected mouse indecent pluripotent stem into a rat who was not able to produce pancreas later rat grew pancreas comprised of mouse cell which was later transplanted into a diabetic mouse as a result mouse diabetic was cured.
On the other hand, human-animal embryos are an entirely new and different concept, the US had produced its own but never made open while other countries have limited research due to lack of funding while some put ban entirely.
