About me: In September of my year, I received higher education at birth and volunteered for embryo engineering, somatic cell cloning, etc. Live in a large villa of nongda. Of course I can speak English.
About You: English Longhair, Silver Gradient. Green eyeballs, pure London accent preferred. Disease-free and moss-free. Together, we can study topics related to the breeding of cloned cats. Contributions to science are welcome.
- A special "marriage notice"
On August 29, the reporter learned from Qingdao Agricultural University that the cloned cat is "safe" and has now reached the age of "marriageable", and the laboratory is looking for a partner for "her".
On December 24, 2020, "Ping An" was born in the laboratory of Qingdao Agricultural University. As the first cloned cat to be completed by a university, he immediately became a "net red cat" in the cat world, which was cute when he was just born.
This is what milk fierceness looks like now
Nine-month-old clone cats enter estrus
Speaking of "peace", it can be said that there is a big deal, researchers from an adult female cat skin tissue, isolated and cultured fibroblasts, using the Chinese pastoral cat egg as a nuclear receptor, through nucleus replacement and artificial activation, to produce a number of somatic cell clone embryos.
After the cloned embryo was transferred to the recipient female cat, after 62 days of gestation, a forest cat somatic cell cloned offspring was successfully obtained.
"Ping An" was born on December 24, 2020, and researchers named it "Ping An".
Dr. Zhao Minghui of the College of Life Sciences of Qingdao Agricultural University said that the team began to prepare for the project in 2019, when it saw a cat in the animal hospital, and after consultation with the owner, the skin the size of a fingernail was removed from it, and the cells were carefully cultured and passed on.
In the second half of 2020, the team began the cloning phase, and there was also a small episode in the middle.
Because the cultivated eggs did not mature, the team members almost chose to abandon, but it was this batch of eggs that were almost abandoned, and the clone cat "Peace" was born.
Recently, Dr. Zhao Minghui sent a circle of friends to solicit marriage for 9 months of "peace". He told reporters that the cloned cat is "safe" to the age, and the team is currently looking for a partner for her.

In fact, the "peace" itself is not a forest cat, but an English long-haired cat, and there are few cats of the same breed, and it is not easy to find an object.
"The cloned ontology was provided by the cat owner, and judging from the photos provided at the time, the ontology was relatively large and looked more like a forest cat when looked at.
But in the process of growing up cloning cats, researchers verified that it was actually an English long-haired cat. ”
Since the birth of "Ping An", all indicators have been very normal, and it has also entered a period of estrus.
Zhao Minghui introduced that if the cloned cat can successfully reproduce and inherit the biological information, it means that the cat is normal, so the team helps "Ping An" to get married in the circle of friends.
However, the team has not yet found a suitable object. Zhao Minghui said that one of the biggest problems they encounter now is that the surrounding British long-haired cats are relatively rare, so he wants to expand the search range through the WeChat circle of friends.
The marriage conditions for cloned cats are very strict, requiring the other party to be an English long-haired cat, silver gradient, good health, and avoid experimental observation due to hybridization.
As soon as the news of the marriage requisition came out, the vast number of shovelers demanded to go to war

In the future, it will turn to the direction of science popularization
According to the team plan, in the future, "Ping An" will turn to the direction of science popularization and enter primary and secondary schools to carry out science education. Zhao Minghui said:
"There will be no further research [on the offspring of cloned cats], the offspring are as long as they are healthy, and we don't intend to experiment with these cats."
Regarding 'peace', the assessment is basically over, and the last indicator is its lifespan. But the indicator of life expectancy takes more than ten years, and the short-term indicators have basically been evaluated. ”
The team will do work on gene editing in cats to make achievements in the pathogenesis of genetic diseases, treatment, and drug development.
