Chinese scientists have successfully cloned two species of Tibetan cows, Zhangmu and Apeijiaz, which are on the verge of extinction. This was done using the method of somatic cell nuclear transfer.
This was reported by The Dairy News Global with reference to the government of the Tibet Autonomous Region.
Scientists collected cells from the ear tissues of two types of cows that live in the highlands of Tibet, and then created a layer of fibroblast (connective tissue cells) in the laboratory. To obtain cloned embryos, scientists used the technology of transferring the nuclei of somatic cells.
“The cloned embryos were transplanted into surrogate cows, and after the full gestation period, we had eight cloned calves,” – said Yu Dawei, a researcher at the Institute of Animal Husbandry and Veterinary Medicine of the Chinese Academy of Agricultural Sciences.

He also noted that in the future, scientists will combine cloning technologies with traditional methods of livestock breeding. This will contribute to the formation of the most genetic system and an improved system of protection and use of resources.
This is not the first animal to be cloned in this way. Somatic cell replacement technology was also used to clone ReTro, a monkey that recently celebrated its second birthday. The technique consists in “interfering” with the work of genes and replacing diseased cells of the embryo with healthy ones.
Researchers say that such technology will help save animal populations that are on the verge of extinction.
