Medical experts say next year in human "kind of" out of the ear

Bone marrow from the ears or a small block in the "seed" and finally "kind of" out of a same ears, this scientific dream has not far away. 　　At yesterday's first world medicine Summit, once said that "in ear" which shocked the world tissue engineering expert Professor Cao Yi Lin, by conducting research on stem cell expansion, in the human body next year out of the ear on regeneration, this technology will be widely used in plastic surgery techniques, instead of silicone to pad the nose, Chin, and so on, this will make cosmetic more natural, less trauma. The "long ears" in nude mice to humans

Tissue engineering is going on? from the normal human body in a small piece of tissue cells, keep it in a large number of amplification, then replant to organizational needs repair parts, let it fix out an entire organization, such as ears, bones, etc. Some people call it "human body", like the printer to print the same clone any piece you need mending bones, skin.

Had transplanted back "a kind of" out of the ear cartilage morphology of countries "973" tissue engineering chief scientist, Shanghai tissue engineering Research Center Director, Professor Cao Yi Lin said yesterday, the leading international research is about to achieve new breakthroughs, "in ear" long to those who have not far away, "the report maybe next year I will not be implanted ear, and is made up of works made by the human ear."

From rat who long to man, faced with some difficult questions: nude mouse ears his "seed" of the cell is taken out from cattle, raw materials have unlimited access, once taken from man, you can't arbitrarily cut ear down to copy another only, this is the "robbing Peter to pay Paul". While limited "seed" cells in vitro for a few generations later, may face "without rice": cell proliferation of feature changes, such as not long ears long scar or a tumor? this is tissue engineering generally faced "specially daughter-in-law" issue.

Cao Yi Lin has recently discovered that take stem cells is a good idea, stem cells is a relatively young cells, it can in the in vitro amplification of 10 g, 20 g without loss of functionality, and can be induced it to various organizations, to "seed" cells add some different micro-environmental stimulation, like cooking oil and salt in sauce and vinegar to make different flavor to the meal, it can be long bones or long long cartilage, skin, last born out of the ear.

"Body parts" recycling easier for facelift

Nude mouse ears had shocked the international plastic profession, when other scientists also attempted to induce long soft ear, Cao Yi Lin has pioneered in vitro regeneration in the ear. "There should be new breakthroughs requires multidisciplinary experts intimately combined" because to "seed" of the cell with "oil-Salt soy sauce and vinegar", the process of differentiation is very complex. Recently, Cao Yi Lin of tissue engineering phase of the project won the national "973" project, and with the Shanghai Institute of Biochemistry and cell Institute of Aeronautics and Astronautics join hands, "oil-Salt soy sauce and vinegar" found molecular expert.

Cao Yi Lin told reporters that "the human body is like the automobile, a part is broken, you can go to the store to buy? some people think that this is a dream, read the organization works in progress, you know this is no longer a distant dream". Although a heart to regenerate, liver, and other complex organs have a long way to go, but copy the ear will bring "dream factories" human body parts. The greatest significance is that it will be widely used in plastic surgery, cosmetic surgery are at present take silicone implants method, but if you take the "body parts", you can attach a "cell" injection into the nose, Chin, and so need to uplift and beauty of the site, and finally let it grow out of the need of cartilage, not only can replace chemical materials, and you can reduce the trauma.
