Scientists have created a Chimera of pig and human

Scientists have grown the world’s first embryos-chimeras composed of cells of man and pig. This is stated in a study published in the journal Cell, reports the BBC Russian.

The proportion of human cells in the embryo is less than 0.001%, the remaining cells of the pig. The embryos allowed to develop for only 28 days. These embryos can help to create a technology for growing human organs inside animals.

Scientists have implanted human stem cells into the embryos of pigs. The result was a mix of human and swine cells, which for a month had placed the female of a pig.

This process was very inefficient: 2 075 implantable embryos within 28 days developed only 186 pieces. However, there had been indications that human cells continue to function as part of the Chimera.

«For the first time human cells have grown in large animal,» explained one of the study’s authors Professor Juan Carlos Izpisua Belmonte from the Institute of biological research Salk.

The low efficiency of the applied method, the Professor explains the long evolution which has separated man and pig.

Now, according to scientists, such chimeras can help in the testing of medicines before testing in humans in the study of the beginning of the development of human diseases. Also, the Chimera can help to study the early development of human embryos and to explain the differences in how function bodies of different living beings. In fact, scientists for this you need to increase the proportion of human cells in the embryo to 0.1-1%.

The position of different States on the question of the legality of the creation of such chimeras is uneven. In 2007 the UK endorsed the creation of chimeras made from human and animal cells, with the proviso that the embryos are not hooked into the uterus of a human or animal for further development. However, in 2015 the National institutes of health, USA the creation of human-animal chimeras did not support and refused to provide funding for such research.

Recall that in January in Ukraine for the first time the child was born from three parents.
