The embryo obtained from stem cells is already fighting the heart, blood vessels, intestines and a nervous system develop. This achievement scientists call the «real miracle», since the new model will better understand the development of mammals at the earliest stage, will improve the testing of drugs, and will also open new opportunities for growing fully functional transplantation organs.

American scientists from Virgin University

Previous models had a lot of problems, so embryos could not fully develop. After a few years of persistent work, scientists managed to solve them. «We found a way to force stem cell aggregates to initiate embryonic development. In response to this controlled instruction, aggregates are developing into embryonic entities that repeat the embryonic stages of development one by one «- commented on the co-author of the work of Christine Tiss.

Scientists were able to get a wide variety of fabrics that are present in the present embryo mice.

«The only way to get all the variety of cells for the formation of functional organs is to develop systems where all predecessor cells are present. Our embryo-like entities provide that, «explained the tees.

The results obtained open up new opportunities in the creation of fully functional organs in the laboratory, which can then be transplanted by a person. Many previous studies have shown that scientists have already managed to create various mini-bodies, but they did not contain all the variety of cells that are necessary for full development.

In addition to the cultivation of organs, scientists are counting in more detail to study the stages of the development of mammals and diseases that are formed in the womb. In addition, the functional models of animals will allow study and test new drugs.
