Peninsula media reporter Liu Jinzhen
Remember the cloned cat "Ping An"? "Ping An" was born in the laboratory of Qingdao Agricultural University. As the first cloned cat completed by a university, it immediately became a "net celebrity cat" in the cat world. On August 29, the reporter learned from Qingdao Agricultural University that "safe", healthy and healthy, and now at the age of "marriage", the laboratory is looking for a partner for "her".
Speaking of "peace", it can be said that there is a lot to do. Researchers isolated and cultured fibroblasts from the skin tissue of an adult female cat as the egg of 2 cat _span. cell nuclear receptor, through nuclear replacement and artificial activation, to produce multiple somatic cell cloned embryos. After the cloned embryo was transferred to the recipient female cat, after 62 days of gestation, a forest cat somatic cell clone was successfully obtained.
"Ping An" was born on December 24, 2020, and scientific researchers named it "Ping An". Dr. Minghui Zhao from the School of Life Sciences of Qingdao Agricultural University said that the team started preparing for the project in 2019. At that time, a cat was seen in the animal hospital. After consultation with the owner, the fingernail-sized skin was removed from its body and the cells were separated carefully. Cultivate and pass on. In the second half of 2020, the team began the cloning phase, and there was also an episode in the middle. Since the cultivated eggs were not mature enough, the team members almost chose to discard them, but it was this batch of almost discarded eggs that gave birth to the cloned cat "Peace".
Recently, Dr. Minghui Zhao posted a circle of friends to marry him for 9 months of "Peace". He told reporters that the cloned cat is "safe" to age, and the team is currently looking for a mate for her. In fact, "Ping An" itself is not a forest cat.It is a British longhair cat . Cats of the same breed are rare and it is not easy to find a target. "The cloned ontology was provided by the cat owner. Judging from the photos provided at the time, the ontology is relatively large and looks more like a forest cat at first glance. However, as the cloned cat grows up, researchers have verified that it is actually one A British longhair cat."
Since the birth of "Ping An", all the indicators have been normal, and he has also entered the estrus period. Zhao Minghui introduced that if the cloned cat can successfully reproduce and inherit the biological information, it means that the cat is normal. Therefore, the team helps "Ping An" marry in the circle of friends. The conditions for marriage of cloned cats are very strict. The counterparty must be a British long-haired cat, with a silver gradation, and in good health, so as not to affect the experimental observation due to hybridization.
According to the team plan, the future "safe" will be transferred to the direction of science popularization, and will enter elementary and middle schools for science popularization education. The team will work on gene editing in cats to make contributions in the pathogenesis of genetic diseases, treatment, and drug development.
