a South Korean research team recently announced the use of bone marrow stem cells to successfully clone pigs,compared with the majority of animal cloning research using somatic cell cloning,the new results of the method can make the success rate of pig cloning significantly increasedIn anatomy and physiology
pigs and people have many similarities, is an important model for scientists to carry out medical researchScientists from Theof Gyeongsang University,Gangwon University,
Zhongbei University,Zhongbei University and other institutions collaborated on the study of cloning pigs using bone marrow stem cells, the website
of the East Asia Daily reportedTuesdayThey extracted interstitial stem cells from the bone marrow of, which weighed about 70 kg, and combined them with the eggs of pigs that had removed the nucleus of their cells, obtained the cloned fertilized eggs by electric shock, and then placed the cloned fertilized eggs in the womb of the sow, which, after a period of incubation, successfully gave birth to cloned piglets The scientists involved in the study noted that previously cloned animals had mainly used somatic cells However, when cloning somatic cells, it is easy to the death or malformation
of fertilized eggs or deformities, abortion , premature birth, the success rate of cloning is only 1% to 5% The success rate of cloned pigs has increased to 2
0% using stem cells
