The interview is about Claire, who worked at a cloning company in South Korea. The company, led by the controversial Professor Wang, mainly clones dogs but also camels, cows, pigs, and is involved in ambitious projects like cloning mammoths for a potential “Jurassic Park” in Russia.
The cloning process involves complex steps, requiring oocytes and cells from the subject to be cloned, and often results in animal suffering, which led Claire to quit her job.
Below is a detailed summary of the information on cloning found in the text:
Cloning Process
- Cloning starts by collecting cells from the subject to be cloned. These can come from hair, ears, or other body parts. It could be a living dog or one that just died – in which case, the sample must be quickly taken by a vet and sent to the cloning lab.
- The cells are cultured to multiply.
- An oocyte (female reproductive cell) is extracted from a donor, and its nucleus – containing half the chromosomes—is removed.
- The cells from the subject are inserted into the enucleated oocyte. An electric shock is applied to fuse the two, creating an embryo.
- The embryo is cultured in the lab and then implanted into a surrogate mother, who may be of a different species or breed than the oocyte donor.
Some clones are born with the heart outside the body or open skulls. You often need 5 to 10 embryos to get 1 to 3 healthy clones.
Those born healthy usually have a normal lifespan.
Clones aren’t identical in behavior or appearance – think of twins. Gestation conditions and mitochondrial DNA from the egg donor also affect the result.
Clients and uses of cloning
- Institutional clients: Some clients include states or government agencies that clone dogs for specialized roles—police, military, detection—for around $15,000 per dog. They clone only the best performers with extraordinary abilities.
- Private clients: Wealthy individuals and families clone their pets for around $100,000. For some, their dog is their whole life.
80% of professional dogs at Seoul airport are cloned.
The royal family of a Gulf emirate has set up a farm of cloned racing and beauty camels in the middle of their military bases.
Ethical Issues and Animal Cruelty
- Animal cloning causes significant suffering, particularly for surrogate mothers and clones born with defects.
- Claire highlights that many cloned animals die or are born with severe abnormalities.
- Surrogates are often mistreated animals in poor health from factory farms.
Mammoth Cloning and “Jurassic Park”
- There’s an international project involving the US, Russia, Japan, and South Korea to clone mammoths using cells found in well-preserved frozen remains in Siberia’s permafrost.
- Putin has invested and encouraged billionaire associates to fund it.
- The goal is to create a “Jurassic Park” in Russia, where mammoths could be recreated and displayed.
- Researchers aim to reconstruct the mammoth genome using elephant oocytes, though the mammoth’s size presents challenges for gestation.
Despite finding well-preserved remains (up to 4,000 years old), no completely intact cell has been recovered, so they are trying to hybridize mammoths with elephants.
Dinosaur Cloning
Dinosaurs have been extinct for millions of years. No living cell remains, so cloning them is impossible with current technology.
Human Cloning
- Human cloning is illegal worldwide, though some research has been done on cloning human embryos for therapeutic purposes.
- These embryos can provide stem cells that may help treat diseases without the risk of immune rejection.
- The goal is to use stem cells to regenerate damaged organs or cure illnesses.
Rumors about human cloning persist, but there’s no confirmed case of a cloned human.
Even if it were possible, cloning someone today would produce a baby—you’d have to wait decades to reach the age of the original.
Anyone hoping to clone their 30-year-old girlfriend would have to wait 30 years for the clone to be 30.
Multiple Clones of the Same Animal
A well-known case is that of a chihuahua named Milly, cloned 49 times. The goal was to study dwarfism, though the clones didn’t inherit that trait.
Cell Preservation for Future Cloning
Animal cells can be cryogenically stored at -196°C in tanks, allowing cloning years after the animal’s death.
Controversial Cloning Practices
Some cloning experiments involve genetic modification, such as grafting jellyfish fluorescent genes onto pigs or dogs to study gene expression.
Risks and Challenges of cloning
- Cloning is highly uncertain – many embryos die or are born malformed.
- Clones may have shorter lifespans or unknown health issues.
- They may also differ in appearance or behavior due to complex genetic and environmental factors.
