The father is not necessary? In China removed posterity from two females of a mouse


Scientists managed to block the sites of DNA preventing start of the program of the correct development of an embryo from two ova. It appears, in Russia similar researches were conducted by the Photo too: depositphotos.com the Chinese scientists brought mice from two females. Their conclusions were presented in the scientific magazine devoted to a research of stem cells, Cell Stem Cell. Little mice were born from merge of the modified and usual ova. Earlier was considered that only fertilization is capable to start the mechanism of development of a viable individual. However and its colleagues found Zhikun Li from Institute of zoology in Beijing the sites of DNA preventing start of the program of the correct development of an embryo from two ova. These genes temporarily disconnected, the turned-out germs implanted to substitute mothers. 14% of germs completely passed all phases of development, 30 mice were born. A third from them gave life to new generation of rodents after pairing with ordinary males. The similar experiment with merge of couple of spermatozoa of viable posterity did not give. Li and his team promised to solve this problem in the nearest future. In Russia conducted similar experiences too, the Dr.Sci.Biol., the employee of Institute of the general genetics of RAS Ilya Zakharov-Gezekhus comments: Ilya Zakharov-Gezekhus the Dr.Sci.Biol., the employee of Institute of the general genetics of RAS "At us at Institute of the general genetics about fifteen years ago such works were conducted, and conducted very well. But to the end result, unfortunately, business did not reach receiving an adult organism. Now our employee doctor of science Platonov, unfortunately, died, and these works already a few years ago were interrupted. The parthenogenesis — receiving posterity without father — is possible in an experiment with fishes, Amphibia, and under natural conditions it is a way of reproduction of some lizards. By the way, too at us now young employees successfully are engaged in it, studying here of such reproduction at lizards. But mammals, at mice, the person have a biological ban which till this time did not manage to be overcome. Obviously, Chinese managed to break this barrier". Earlier it was already reported about similar successful experiments on removal of mice without participation of the father. In the 2004th it was made by scientists in Japan and in the 2016th in Great Britain. To add BFM.ru to your sources of news?
