Chapter 2414 Cell Cloning Printing and Transplantation Technology
In addition, our other smart bionic artificial organs and tissues are also being actively promoted as part of the smart bionic organ project, and have also made very good progress. When we have results, we will promptly
Report to everyone.
Wu Hao added, and then continued: "In addition to this kind of intelligent bionic artificial organs, we are also actively researching bio-3D printing organ tissue technology, and human cell tissue cloning and cultivation technology. At present, we can already realize some small
Cell cloning printing and transplantation technology for tissues and organs.”
At this point, Wu Hao paused and waited for everyone in the audience to calm down and concentrate on looking at him before he continued to speak.
These two technologies seem to be two independent technical categories, but we have magically combined them. If we want to print an organ tissue that can be transplanted to an injured or sick patient, we must first
Somatic cells are collected from the patient.
This is because the somatic cells extracted from the patient are cloned and cultured, and printed into organ tissue and transplanted to the patient, there will be no rejection reaction. This is one of the biggest advantages of this technology, which means that we can clone and print
The artificial organs and tissues that come out are no different from the original ones in your body.
After these somatic cells are taken out, they will be processed and then cloned and cultured to produce enough somatic cells. This is the raw material for biological 3D printers and is basically equivalent to the consumables of ordinary 3D printers.
After we have the raw materials, we will use a bio-3D printer to print. Before printing, we need to draw a diagram of the organ tissue structure of the printed part. We must first understand the structure of these organs and tissues, so that we can have targeted
These organs and tissues can be printed out permanently. Otherwise, what is printed is just a piece of waste meat.
And this gave rise to another technology, which is the ultra-fine 3D digital model of the human body. Everyone knows about the 3D digital model of the human body, and it is also understandable about the ultra-fineness, but everyone is not sure what level of ultra-fineness it can achieve.
.
Let me tell you this, the consumables used by this biological 3D printer are somatic cells, which also means that its printing accuracy is at the cell level, so this ultra-fine 3D digital model of the human body must also be at the cell level.
To draw such a detailed 3D digital model of the human body is a huge task, which means we have to break down the human body into cells. And the total number of cells in a normal person is about 40 trillion to 60 trillion cells.
Or so, it is basically impossible for this work to be done by people.
Hearing the figure reported by Wu Hao, the audience couldn't help but exclaimed. This is almost equivalent to half a year's GDP of the country. If someone were to complete it, it would probably take thousands or tens of thousands of years to complete.
Seeing the reaction below, 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 will continue to make corrections to obtain a more accurate 3D digital model data of the human body.
Then, we can use this ultra-fine human body 3D digital model data to print out the required organ tissue parts. However, these printed organ tissue parts cannot be put into use immediately, but need to be continuously verified to ensure that these
Organs and tissues have the same physiological functions as before, and they can remain stable and not prone to change.
Because this project is relatively ambitious, currently we are only able to replicate and print human skin tissue, muscle tissue, including nerve tissue, various arterial and venous blood vessels, including cardiac tissue.
And I am very proud to tell you that the various types of 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 participated in the rescue?"
After hearing Wu Hao's words, many people in the audience began to answer. Wu Hao smiled and nodded: "Yes, it is Ms. Zou Feifei. She was burned by the fire while trying to rescue the passengers in the hotel. Fortunately, the firefighters
They arrived in time to rescue her and saved her life, but she was severely burned and disfigured.
This made Zou Feifei very painful, and she even committed suicide. After learning about her heroic deeds, we immediately contacted the other party and brought her and her mother to Anxi for treatment.
By that time, her superficial burns had healed, but severe burn scars were left, especially on her face and head. In addition to severe skin burns, there were also injuries to some deep muscles, nerves, and blood vessels, including one on her head.
Eye.
So we immediately convened some domestic medical experts with rich experience in the treatment of burns, as well as 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, then repair her damaged skin and use bio-3D printing technology to give her a new face.”
When Wu Hao was introducing, the three naked-eye 3D projection screens above his head were also playing relevant images.
Wu Hao paused for a moment, glanced at the people in the audience, and then continued: "The entire treatment process is very complicated. We need to clean the damaged parts of the patient first and remove the damaged muscles, nerves and vascular tissue.
Then, Zou Feifei's somatic cells were used to clone and cultivate 3D bio-printed tiny muscle fibers, blood vessels and nerve tissue, and then gradually transplanted them to Zou Feifei's face.
As we all know, the muscle, nerve and blood vessel 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 complex treatment project, and there is no shortcut, so we proceed step by step intelligently.
Most of the time, the patient may have to perform a recovery operation every week. After several operations, we finally completed the repair of her facial muscle, neurovascular tissue, including the nasal cartilage, eyeball muscles, and ear cartilage.
etc.
After completing the basics, we begin to repair the patient's facial skin. Usually, there are three technical methods for repairing and cosmetic surgery on disfigured patients. The first is to perform surgical cosmetic reconstruction on the original basis, through surgical intervention.
, allowing people to grow ideal skin naturally. However, the effect of this surgery is so poor that it has basically been abandoned.”
