Hiromitsu Nakauchi, a stem cell biologist working to undertake experiments with human-animal embryos, has made a big advancement. Japan has approved these studies, in contrast to other nations that forbid such research.
Nakauchi, a researcher at Stanford University and the University of Tokyo, wants to grow human organs in animals like pigs or sheep, which could benefit people who require transplants. Although growing human organs using this method is still a long way off, getting approval for his research is a significant accomplishment.
Beginning with the injection of human stem cells into specially modified rat and mouse embryos, the allowed research will be conducted. The human cells may aid in the development of functional pancreases because these embryos are unable to produce pancreases on their own.
For almost two years, scientists will keep an eye on the animals to monitor their growth, organ development, and mental activity. Later, they’ll apply for permission to conduct comparable pig experimentation.
Because the embryos are given the opportunity to grow into animals, this research is unique. What kind of cells the human stem cells might develop into within the animals is a source of worry. Nakauchi will proceed cautiously, ensuring that people comprehend and believe in his efforts.
