Vol 5 Chapter 2414: Cell clone printing transplantation technology

In addition, our other intelligent bionic artificial organs and tissues, as part of the intelligent bionic organ project, are also actively advancing, and have also made very good progress. When the results are obtained, we will promptly Report to everyone.

Wu Hao added a sentence, and then went on to say: "In addition to this intelligent bionic artificial organ, we are also actively researching the technology of biological 3D printing organs and tissues, and the cloning and cultivation technology of human cells and tissues. Cell clone printing transplantation technology of tissues and organs."

Speaking of this, Wu Hao paused for a while, waited for everyone in the audience to calm down and focused on looking at him, and then he continued to speak.

These two technologies seem to be two separate technical categories, but we have magically combined them. To print an organ tissue that can be transplanted into an injured or diseased patient, we must first take somatic cells from the patient.

This is because the somatic cells extracted from the patient are cloned and cultivated, and after being printed as an organ tissue and transplanted into the patient, there will be no rejection reaction. This is one of the biggest advantages of this technology, which is that we can clone and print artificial organ tissue that is indistinguishable from the original on your body.

After these somatic cells are harvested, they are processed and then cloned to produce enough somatic cells. This is the raw material of biological 3d printers, which is basically equivalent to the consumables of ordinary 3d printers.

After we have the raw materials, we will use the biological 3D printer to print. Before printing, we need to draw a map of the organ tissue structure of the printed part. We must first understand the structure of these organs and tissues, so that these organs and tissues can be printed out in a targeted manner. Otherwise, what is printed is a piece of scrap meat.

And this gave birth to another technology, that is, ultra-fine 3D digital models of the human body. Everyone is aware of the 3D digital model of the human body, and it is understandable that it is super-fine, but everyone is not quite sure of the level of super-fineness.

Let me tell you this, the consumables used in this biological 3D printer are somatic cells, which also means that its printing accuracy is at the cellular level, so this ultra-fine 3D digital model of the human body must also be at the cellular level.

To draw such a detailed 3D digital model of the human body, the work is so huge that we have to decompose the human body into cells. And the total number of cells in a normal person is about 40 trillion to 60 trillion grains. If this work is done by humans, it is basically impossible.

Hearing the number reported by Wu Hao, the audience couldn't help but let out an exclamation. This is almost equivalent to half a year of gdp in China. If people do it, it will take thousands of years to complete.

Seeing the following reaction, Wu Hao continued with a smile: "At this time, the intervention of supercomputers can help us accomplish many things. Through a series of complex mathematical formulas and models, we can automatically generate this ultra-fine 3D digital model of the human body. Then we can make continuous corrections to get a more accurate 3D digital model data of the human body.

Then, we can use this ultra-fine human 3D digital model data to print out the required organs and tissues. However, these printed organs and tissues cannot be put into use immediately, but continuous verification is required to ensure that these organs and tissues have the same physiological functions as the original ones, and can remain stable and not easily changed.

Because this project is relatively grand, at present we only realize the replication and printing of human skin tissue, muscle tissue, including nerve tissue, various arterial and venous blood vessels, including myocardial tissue.

And I can proudly tell you that the various organs and tissues we have printed have been used in clinical trials and have achieved excellent therapeutic effects.

Do you still remember a fire-fighting heroine we once participated in the rescue? "

Hearing Wu Hao's words, many people in the audience began to answer. Wu Hao nodded with a smile: "Yes, it was Ms. Feifei Zou. She was burned by the fire in order to rescue the passengers in the hotel. Fortunately, the firefighters arrived in time to rescue her, which saved her life, but she herself is already serious. Burns, disfigurement.

This made Zou Feifei very painful, and even had a suicide year. After we learned of her heroic deeds, we immediately got in touch with the other party, and took her and her mother to Anxi's side for treatment.

At that time, her superficial burns had been cured, but she left severe burn scars, especially on the face and head. In addition to the severe burns on the skin, some deep muscles and nerves were damaged, including a Eye.

Therefore, we immediately convened some domestic medical experts with rich treatment experience in the field of burns, and some of our technical experts to form a joint expert group to treat Zou Feifei.

After consultation and consultation, we decided to start repairing the deep muscle tissue and neurovascular tissue of Zou Feifei's burn site first, and then repair the damaged skin, using 3D bioprinting technology to replace her with a new one. new face. "

When Wu Hao introduced, the three naked-eye 3D projection screens on his head were also playing relevant pictures.

Wu Hao paused, glanced at the people in the audience, and then continued: "The whole treatment process is very complicated, we need to clean the damaged part of the patient first, and remove the damaged muscle, nerve and blood vessel tissue.

Then, using Zou Feifei's somatic cells to clone and cultivate biological 3D prints out these tiny muscle fibers, blood vessels and nerve tissue, and then gradually transplant them to Zou Feifei's face.

As we all know, the muscle, neurovascular network of the human face is very complex, and it is very difficult to completely repair it. This can be said to be a very large and complicated treatment project, and there is no shortcut to take, so we intelligently proceed step by step.

Most of the time, the patient may have to undergo a recovery operation every week. After several operations, we finally completed the repair of her facial muscles and neurovascular tissues, including the nasal cartilage, oculi muscles, and ear cartilage. and many more.

After completing the foundation, we begin to repair the patient's facial skin. Under normal circumstances, there are generally three technical ways to perform cosmetic surgery on disfigured patients. The first is to perform surgical cosmetic reconstruction on the original basis. Through surgical intervention, people can naturally grow ideal skin. However, the effect of this operation is so poor that it has basically been abandoned. "
