Chinese scientists have grown and transplanted ears once five children
Scientists from China have grown new ears for five children born with microtia - insufficient development or complete absence of the pinna.
Each of the bodies has been obtained from the patient's own cells. Specialists have the necessary forms with the help of 3D-printing technology.
According to statistics, with microtia - deformation of the ear - is born one of the five thousand children. As a rule, in this case instead of a baby's ear - a small bump or lobe. External flaw in most cases is accompanied by hearing loss. Previously microtome eliminated via reconstructive plastic surgery ear formed from synthetic materials or from rib cartilage portion of the patient and is attached to the head.
But in the near future, most likely, similar operations will be conducted by the new technology. Chinese scientists have conducted a successful experiment to reproduce the ear of the patient's own cells. To do this, from the affected ear microtia have identified the main cells of the cartilage - chondrocytes. Then they filled in a special biodegradable framework and cultured for three months. To give the new cartilage desired shape, specialists have used CT scans and printed the 3D-printer model healthy ears of patients.
3D-print - it's just a method of applying the cell. The main achievement lies in the fact that the number of cells able to bring to such a state that they could form a tissue. It should be applied to precursor cells, which are then transformed into the fabric. But these cells to begin with it is necessary to highlight. Where you basically play the role of achievements in the field of stem cells, "- he explained researcher Institute of Physico-Chemical Biology. Belozersky MSU Alexey Nesterenko, reported RT
