Japanese scientists have grown from stem cells of the liver
In a paper published in the scientific journal Nature article says: “This is the first recorded case showing the ability to create a functioning human organ from pluripotent stem cells.” By this scientific breakthrough came by Japanese scientists from the City University of Yokohama (Yokohama City University), who announced that for the first time thanks to the use of stem cells, they have built a working man’s liver.
The paper points out that for two months, scientists were able to grow from induced pluripotent stem cells fully functional liver, as if it was in the early stages of its formation. In the words of scientists, they transplanted the “harvesting” of the cells in the laboratory mouse, and soon discovered that the cells have adapted and connected to the circulatory system of a rodent. Two months later, they were transformed into the body that has to perform all the functions of the liver.
To test its performance scholars have raised mouse blood pressure and imposed anti-inflammatory drugs, which under normal circumstances, have different effects on the human body and the body rodent. The results were surprising. In fact, these medications were harmful normal mouse liver, but instead their livers processed in the same way as it does ordinary human.
The article points out, despite the fact that prior to the actual possibilities of using this method to treat people so far away, a new discovery in the future will provide ample opportunities for regenerative medicine. Scientists say that their next step would be to test methods of cultivation of liver stem cells are directly in humans. And if not as a permanent graft, at least as a temporary alternative to organ damage.
