Scientists in Japan, led by Professor Hiromitsu Nakauchi of Stanford University, are set to break new grounds in the realm of biomedical research. They have been granted government approval to initiate experiments aimed at growing human organs within animal bodies. Regarded as a pioneering venture, this research will attempt to generate animal embryos — notably mice, rats, or pigs — that lack specific organs such as a pancreas and imbue them with human pluripotent stem (iPS) cells capable of growing into the required organ.
The Modus Operandi
The modified embryos would then be implanted with human “induced Pluripotent Stem (iPS)” cells which hold capabilities to grow into the missing organ. Subsequently, these scientifically altered embryos would be transplanted into surrogate wombs where, theoretically, they could be gestated to full term, while nurturing a functional human pancreas inside them.
Understanding Chimeras: The Crucial Concerns
By introducing human cells into animal embryos, the researchers effectively create a chimera – a biological entity possessing both animal and human cells. This process, although potentially revolutionary, raises some notable ethical questions. One of the main concerns lies in the inability to entirely control the formation of organs by human iPS cells within the animal’s body. This uncertainty fuels worries about cross-species mixing at the cellular level and what implications it may bear.
Envisaging the Benefits
The possible positive impacts this research could have on the field of organ transplantation are profound. If successful, this line of experimentation could pave the way for a future where organ donors need not be solely human. Animals could potentially serve as ‘organ farms’ to grow human organs, drastically reducing the scarcity of organ donors and increasing accessibility for patients in desperate need of transplants.
