Scientists first grown in the laboratory bone tissue. Now doctors will be able to restore the bones of people who, because of serious injuries, amputation of limbs. About the work done, the scientists told in the journal Nature Biomedical Engineering.
A team of scientists from Scotland and Ireland has developed a device that generates nanovibrations and conducts them through a collagen gel suspension of mesenchymal stem cells that can differentiate into osteoblasts, bone cells. Thus, the cells form a "bone putty", as it is called by researchers, which can then be used to treat fractures and diseases that damage bone tissue, the Main reports with reference to 24news.
The development was based on a technique borrowed from physicists used to study gravitational waves.
Through special cameras, scientists let in vibrations with an amplitude of 20 nanometers. This frequency of vibration leads to the formation of bone tissue from cells.
Collagen gel allows them to form a three-dimensional structure. Since collagen is the main component of human connective tissue, this gel is biologically compatible with the tissues of the patient.
Scientists promise that the method will be tested on a man in 2020. They plan to restore with the help of "putty" the patient's arm bone.
