In February of 200 1 year, a special live mouse caused a sensation in Beijing-a white mouse with red eyes, long tail and no hair. Unusually, this mouse has a "human ear" on its back that is almost the same size as its body. The "human ear" on the mouse's back shows a scientific research achievement of China's "863" project. The "human ear" on this mouse was copied by Professor Cao Yilin, vice president of Shanghai Ninth People's Hospital and director of plastic surgery, using tissue engineering technology.

A mouse with a "human ear" on its back was airlifted from Shanghai to Beijing and checked into a hotel. The "human ear mouse" was put in a transparent box when it was exhibited. There was no water, no feed and no device for filtering air in the box. Therefore, each exhibition only lasted one or two hours. The exhibition lasted several days. Although tickets are as high as 20 yuan, there are still nearly 200,000 people willing to spend money to see the "human ear mouse". Mice with "human ears" appeared in Beijing, revealing a message-with the revelation of the mystery of human life, one day the human body will be like a car. If any part is broken, you can buy a new one and install it.

During the period of 199 1, Professor Cao Yilin made new achievements in chondrocyte transplantation, which caused a shock in the international medical community. 1996, when Professor Cao Yilin introduced this technology and theory to China. From 65438 to 0999, the Ministry of Science and Technology listed "Basic Scientific Problems of Tissue Engineering" as a major national basic research and development plan, namely "973 Plan".

Professor Cao Yilin said that the key to making "human ear mouse" is "human ear". Firstly, polyglycolic acid, a polymer chemical material, was used as a model scaffold for adult ears, and cells were allowed to reproduce and grow on this scaffold. Then cut a hole in the back of the nude mouse, implant the cultivated "human ear" and sew it. The "human ear" scaffold will eventually degrade and disappear by itself, so the "human ear" will be integrated with the mouse.

Look at the first paragraph: "It was copied by tissue engineering technology." And looking at the whole report, we can see that it has nothing to do with genes, but a cell-level study.

There is no doubt that the real meaning of "human ear mouse" is not to make mice grow "human ears", but to make the copied "human ears" bring good news to patients. Professor Cao Yilin said that the "human ears" on mice are just external ears and have no hearing function. If the patient's inner ear is not damaged, perfect hearing can be obtained through external ear plastic surgery.
