What you need to know:
Scientists in China have just announced that they have a new cloned monkey and some experts are already talking about future human copies.
Two years ago we told you about the cloning of an arctic wolf in this same country and now, in 2024, Chinese scientists have announced with great fanfare that they have a new cloned monkeyso some experts are already talking about the possibility of future human copies… Can you imagine it?
China has a new cloned monkey
It was in a study published in the journal Nature that scientists from China announced that they have a new cloned monkey and it even has a name, since they called it “Retro”.
Yes, it is a monkey rhesus that “was born” on July 16, 2020 and is now three years old, according to Asian experts.
It should be noted that a few years ago Scientists in China had already cloned two monkeys of the species cynomolgusa type of macaque, which they announced in 2018. In fact, until this date, These two animals are still alive.
In this regard, the experts involved in the new experiment assured that the cloned monkey rhesus still alive and healthywhich already means a big step in this type of research.
How did they clone him?
In case you didn’t know, the first mammal cloned was the famous sheep Dolly, in 1996, using a technique called somatic cell nuclear transfer or SCNTin which scientists reconstructed an unfertilized egg by fusing a somatic cell nucleus that does not come from a sperm or egg, with an egg from which the nucleus has been removed.
In the case of the new cloned monkey, Chinese experts used a modified version of this techniquebecause in their first attempts, they realized that the placenta did not form properly in the embryos they cloned.
Then they carried out a process in which they put cloned internal cells into a non-cloned embryo, which allowed the clone to develop without problems.
And to be sure of their new technique, they did 113 tests on reconstructed embryos, 11 of which were transferred to seven surrogate mothers, and then of these only one survived successfully.
Human copies in sight?
After this successful experiment with which a new cloned monkey was obtained in China, experts say that This could help accelerate biomedical research.
However, as CNN mentions, this experiment has also raised some controversy. On the one hand due to ethical concerns about animal welfare; and on the other about future experiments in human cloning.
But others consider that the low success rate in animal cloning suggests that human copies will be difficult to obtain and also unnecessary and unacceptable…What do you think about this topic?
