| According to foreign media reports, Chinese scientists recently used 5 children's cells and 3D printing technology to cultivate new ears for them. It is reported that these 5 children range in age from 6 to 9 years old, and they suffer from congenital small ears Although hearing loss occurs in the ear with small ear disease, the hearing of the other normal ear will not be affected in most cases.  So for scientists to cultivate new ears for greater purpose is for aesthetic reasons.First, the scientist through the healthy ear to create a 3D print model, and then flip it and make the other that is only sick Ear model; then they extracted the chondrocytes from the deformed ear for 3 months in a biodegradable 3D model; and finally, they transplanted this regrown ear to the child. Tessa Hadlock, head of facial and plastic surgery at Massachusetts Eye and Ear in Boston, points out that the idea of using an own cell to culture an alternative organ has been around for years and was previously tested on animals but is much more risky if it comes to being a human, Because if the cells grow too much then it will cause cancer mass.According to scientists, the children who underwent the transplant are currently healthy. Unfortunately, this treatment is complex and expensive, so it is still difficult to gain popularity at the moment, but it is still a big step forward to develop chondrocytes to repair deformed ears. |
