Chapter 734: Champion
Rahal's team acted decisively and put all their efforts on liver transplantation.
First, the experimental pigs.
Rahal's team surgically diverted the blood supply of six pigs from the liver, artificially causing liver necrosis.
Then healthy liver cells were injected into the pigs' lymph nodes.
The dosage range was also gradually increased, from a minimum of 3 lymph nodes with 360 million cells injected, to a total of 1.8 billion liver cells injected into 18 lymph nodes.
While waiting for the development of the micro-organs, the six experimental pigs relied on the blood filtration equipment of the artificial kidney to maintain their lives.
Four months later, the six pigs gradually recovered from liver damage, and the liver function of all pigs improved!
The autopsy of these experimental pigs found that healthy miniature livers had grown on their lymph nodes, and the rest of the naturally grown livers had similar tissue characteristics and the ability to produce bile acid.
Moreover, over time, the lymph nodes will eventually disappear, leaving only highly vascularized miniature livers, which can filter blood circulation through the highly vascularized structure inside, thereby maintaining liver function!
...
Lahar was beaming with joy, as if he saw the future of organ transplantation in this study.
"The reason why we chose lymph nodes is that they are everywhere in the body!
"Lymph nodes not only maintain the body's immunity, but also have a good blood supply, which can help new organ tissues grow quickly. For example, during the experiment, we found that there were lymph nodes near the liver. Although the liver of the experimental animal was necrotic, the lymph nodes could still receive the chemical signals released by the necrotic liver, which stimulated and promoted the regeneration of liver tissue!
"I gave this type of lymph node a name: organ incubator!
"In the liver area, it is a liver incubator. There may be more in the future, such as lung incubators, kidney incubators, heart incubators, etc.!
"I saw the best solution for organ transplantation in allogeneic cell therapy, which will be a technology that will completely change the medical field!"
After Lahar finished his speech, the whole audience was in an uproar.
Rather than saying that this is an organ transplant, it is more appropriate to say that it is actually an organoid transplant.
Although various micro-organs are very different from the original organs, they can play the functions of natural organs!
Even if it only has basic functions, it is a life-saving treatment for a terminally ill person who has no organs to replace!
"Not only that... If allogeneic cell therapy can be popularized, there will be no need for large-scale organ transplantation in the future. Only minimally invasive implantation and waiting for the lymph nodes to grow micro-organs are needed!"
"It is indeed Lahar! It is worthy of being the country of berries!"
"This technology is too important. The country of berries will lead the next organ transplantation revolution!"
The contestants in the audience were shocked.
Xu Qiu was also looking forward to it, but he considered more things.
For example... This technology is currently only carried out on experimental animals, and there are very few samples. If you want to apply it to humans and popularize it in the clinic, there is still a very long way to go.
This time, at least seven or eight years, can only be applied after long-term observation, testing and verification of whether the technology has potential risks.
Moreover, how many functions can the micro liver replace, and can it cope with the more sophisticated and complex human blood circulation?
In short...
Rahal's idea is very beautiful, and the prospect of allogeneic cell therapy is also very exciting, but no details are mentioned, which cannot withstand careful scrutiny.
On stage.
Judges such as Beimudong obviously saw this.
The step taken by Rahal pointed out a new path for organ transplantation. If allogeneic cell therapy can continue to develop, it may really replace organ transplantation in the future, and use organoid transplantation to save the lives of countless terminal patients.
Organ incubator...
Micro-organ...
These words all mark the arrival of a future era.
Perhaps decades later, people of that era will see incubators, micro-organs, etc., just like people today see organ transplantation in textbooks, sparse and common.
But, this is after all decades later.
The step taken by Rahal is so big that it can change the entire organ transplantation, but at the same time it is too far away from the clinic. This novel method only brings organoid transplantation to the table and points a way for countless researchers. It is still at least decades away from popularization.
"Innovation 96 points. Application value 84 points. Potential 95 points."
"Final score: 91.5 points!"
When the results were announced, there was a burst of exclamations in the venue.
The champions of previous world championships scored around 90 points, and this time Lahar's final score was as high as 91.5 points, almost securing the championship.
The highest score of the other competitive countries was Selena's 83 points, which was 8.5 points lower than Lahar!
"Sure."
"The champion is indeed Lahar!"
"Among the contestants behind, only Abel from the Orthopedic Country and Maple Leaf Country are worth watching, but they can break the record by getting 85 points, how can they surpass Lahar?"
"..."
The contestants in the venue looked at Lahar... This is the real human genius, born in the Berry Country, standing at the top of the Berry Country geniuses, who can compete with him?
...
Then, Abel, the representative of the Orthopedic Country behind Lahar, also came on stage.
His achievement is 3D printing and hand-brain reconstruction.
This project was originally a technology that Professor Noah had hidden for many years. Later, after going to Linyi, with the help of Xu Qiu, it finally took shape. With the help of the surgical strength of the orthopedic country itself, plus the research in the past six months, Abel finally completed it.
The project is divided into two parts.
The first is 3D printing.
The essence of the technology is not difficult. It is nothing more than digitizing the image data of both hands, post-processing, and then using mirror technology to generate the shape of the affected side of the part required for reconstruction. Finally, use a 3D printer to print out a metal prosthesis, and then combine it with the transplantation of own tissue.
This technology is already very common at home and abroad. Xu Qiu used a 3D printed alloy prosthesis to reconstruct the tibia for Chen Mengxuan.
But Abel further improved the technology, making the 3D printed prosthesis closer to the original part and reducing the risk of vascular crisis.
To put it simply, if Abel's technology had been available earlier, it would not have been only Xu Qiu who dared to perform Chen Mengxuan's surgery. At least Lin Xie dared to perform it on the operating table, and the directors of hand surgery at top hospitals such as Union Hospital and West China Hospital also had a high success rate!
The other part is the reconstruction of the hand and brain!
If the former is the improvement and perfection of hand surgery technology, it is to stand on the shoulders of great men.
Then this reconstruction of the hand and brain is a truly subversive and shocking achievement!
