American biotechnologists have managed to grow artificial analogues of human bones, using the technique of reprogramming cells. According to one of the scientists from the new York Foundation for stem cell Giuseppe de Peppo, new achievement is almost universal way of treating patients, during which does not require transplantation of living tissue.
Dr. de Peppo together with colleagues managed to grow the first fragments of bone tissue after the experiment with stem cells that were grown from skin cells of a person. During their experiments, the scientists were able to identify three methods, which allow sozdat harvesting bone from stem cells. To check the quality of the obtained artificial bone, scientists implanted them into mice whose immune system was not working, starting before birth. Thus biologists wanted to check how often the implants are transformed into malignant neoplasms.
After a series of experiments specialists finally managed to select the most stable bone samples, which have retained their function and form at the end of three months after their transplant.
Scientists believe that this technique will continue to grow, so-called "bio-prosthesis, which can replace the damaged bones in the human body.
