Technology's opening live broadcast to build rockets

"Our team in the island country has successfully designed the cultivation and transplantation of epithelial cell layers for the regeneration of cornea, esophagus, joints, and periodontal tissue, which has greatly improved the clinical efficacy of related diseases. In the next stage, we will study the ear , nose and other large organs." At the academic exchange meeting, Oki Satoshi, a medical expert from the island country, proudly described.

The results obtained by his team have been published in international medical journals and are hailed as the gospel of "human organ cultivation"!

"The research results of Professor Ohgi's team are obvious to all." Hanfang's research team is led by Professor Park Jingxiu of its famous medical research institute. He first praised the research results of Professor Ohki's team, and then said: "We are promoting regeneration genes. We have made new discoveries in medicine. The pro-regenerative gene medicine we developed can be inserted into cells during the cell culture process to promote cell regeneration and development."

The achievements of Park Kyung-soo's team attracted applause from all parties.

In the process of cell or organ cultivation, regenerative gene drugs are a very important component.

"We cultured human gastrointestinal tissue, including gastric parietal cells and intestinal parietal cells." said Professor Joseph, the leader of the French team.

"Our research on stem cell cultivation has been published in Cell before, and everyone should have read it." Dutch expert Basten said.

Every team has achieved good research results.

Before Xie Ziqian could speak, Damuzhi asked curiously: "This in vitro organ cultivation project is jointly carried out by five of our teams. Logically speaking, your Peking University research team should study stem cell induction technology. Why haven't you seen anything during this time?" Do you publish your results?”

There was some complacency in his question. Logically speaking, the Peking University team should have published some results.

But from the beginning of the project to now, they have not published any important research results. In the past six months, it has become even more like becoming invisible.

Omuzhi guessed that maybe their team had not achieved any valuable research results, so they were embarrassed to say it.

"Yeah, I'm very curious too." Joseph asked, "This project was initiated by you. We are here for academic exchanges and we really want to see your research results."

Park Jingxiu, Basten and important members of their respective teams all looked towards the Peking University team.

It would be a joke if, as the host, there was nothing that could be brought out for "communication".

Xie Ziqian was not panicked at all, and even looked forward to it.

He smiled and said: "Everyone, during this period, our team has been concentrating on research and has not published any results because it has made a 'historic' breakthrough."

"At this exchange, we are trying to present our research."

"Mr. Xie, what breakthrough have you made?" Park Jingxiu asked.

Xie Ziqian slowed down his speech and spoke fluent English so that these foreign experts could understand him.

"Not only did we successfully induce and differentiate stem cells in vitro, we even grew mouse kidneys in vitro and the transplantation was successful!"

"You have grown mouse kidneys in vitro?" Xie Ziqian's words made these foreign experts tremble and all showed expressions of surprise.

"Are you talking about the kidneys? Not the cells or tissues of a certain part of the kidneys?"

"It was cultured outside the body? And the transplant was successful?"

"Is this true?" They couldn't believe it. Their results were already very impressive, but the research results Xie Ziqian mentioned were completely incomparable even if the four teams of them combined worked together!

"Of course it's true." Xie Ziqian was very satisfied when he saw their surprised expressions. He continued: "This is also thanks to the new member of our team, Mr. Du Xingyu. Everyone must have heard of his name. ”

"Du Xingyu, I know!" Damuzhi said immediately, "Is he the genius from Peking University who cloned the Tyrannosaurus rex?"

"It's him again. Who is he? Where is he?"

"Professor Damuzhi, I am Du Xingyu." Du Xingyu was sitting next to Xie Ziqian.

Damuzhi was even more surprised when he saw Du Xingyu. He immediately stood up, stretched out his hand and said: "Mr. Du Xingyu, I have admired your name for a long time and have always wanted to communicate with you. I never thought that I would meet you here. This is my honor!"

Du Xingyu shook hands with him, and experts from other countries also stood up to get to know this young man again.

Before the exchange meeting started, they all thought that this young man was Xie Ziqian's assistant, translator or student.

Who knew that he was actually the one who cloned Tyrannosaurus rex, and also played a huge role in this research!

"Mr. Du Xingyu, I would like to know where your current research is at? Can you tell me more about it?" Park Jingxiu was very curious.

"Of course." Du Xingyu nodded slightly, and then said: "Currently, we have successfully cultivated mouse kidney organs in vitro and performed transplantation operations. The physiological characteristics of the ten mice undergoing organ transplantation are all very normal. Any rejection reaction occurs.”

"So we conducted a phase 2 trial to grow human kidney organs in vitro."

When he said this, these foreign experts were stunned.

"You have started growing human organs in vitro? How is this done?"

"Can a kidney really be grown outside the body? Will it survive?"

"Even in vitro cultivation of organs like ears and nose is already very difficult. You actually want to try human kidneys. This idea is too bold!"

"How is the progress?" Professor Joseph from France asked.

"Currently we have cultivated a human kidney organ and will perform a transplant operation in ten days." Du Xingyu said.

"Is the transplant operation ready?" These experts were even more confused. This progress was simply exaggerated!

It's like everyone agreed to build a car together. Some teams produced the engine, some produced the body, and some produced the driving system. But Du Xingyu directly announced that they had built the aircraft and were ready to test it!

"Mr. Du Xingyu, and Mr. Xie Ziqian, I would like to make a bold request to observe and learn transplant surgery!" Damuzhi said immediately.

"I also have such a request!" Park Jingxiu followed.

“Hopefully we can also watch and learn,” both the French and Dutch teams said.

They didn't quite believe what Du Xingyu and Xie Ziqian said. The research progress of this Peking University team is so fast that it seems to have jumped decades.

They proposed to observe and learn, and also wanted to know whether this matter was true or false.

"Of course." Xie Ziqian smiled, "That is the purpose of academic exchanges."

"This is our first trial, and there is no guarantee of success. I hope you can give some suggestions."

…

After the first day of the meeting, expert teams from each country met privately.

"Professor, are they telling the truth? Can they grow human kidneys in vitro?" asked a member of Okichi's team in the island country.

Omuzhi frowned and thought deeply, and said: "I don't know, this matter is too outrageous. Logically speaking, they shouldn't deceive us like this, because we can expose it soon."

"If they really did it..."

Okichi took a deep breath and said: "That will change the world. China, especially their team, will become the light of mankind for stem cell cultivation, organ cultivation and organ transplantation!"

…

"I want to see what the Chinese are doing?" Park Jingxiu of the Korean team explained, "I'll have more contact with their team in the past few days to see if they are really in vitro-cultured organs."

"If they dare to use other people's donated kidneys to fool us... Humph!"

…

"I think it is absolutely impossible for them to grow human kidneys in vitro!" Professor Joseph was contacting domestic research institutes.

"Just the induction of stem cells is very difficult to achieve. They actually said that they can simply grow large human organs in an external container. This is an obvious lie!"

"If they fool us, I will quit the academy. It's an insult!"

Like him, the Dutch team is also testing the truth and wants to know the specific situation.

In addition to the technology that needs to be kept secret, Xie Ziqian's team did not hide it and showed them the container in which the second mouse kidney cultivation experiment was being carried out.

When you look at the in vitro culture vessel, you actually have growing, healthy mouse kidneys. These foreign experts were once again dumbfounded. Even if they did not grow human organs, this alone would be enough to alarm the biology and medical circles!

They are also more concerned about the organ transplant surgery in a few days.

…

A few days later, the operating room of Peking University Affiliated Hospital.

Sun Dahai, a uremia patient, was transferred to the operating room. Now his kidney function is completely close to "disabled" and he must undergo dialysis every day to survive.

Sun Dahai himself was very worried about this medical experiment.

If it weren't for the fact that he couldn't find a kidney source and the hospital was willing to provide free organ transplants, he wouldn't have taken the risk of being a "guinea pig" for this experiment.

"We will try our best." Jing Jian, the surgeon in charge of the operation, comforted Sun Dahai's family members.

Last time, he performed a kidney transplant on a mouse. This time, he will perform the operation on a real patient. This is the first artificial in vitro cultured organ transplant operation in human history, and dozens of experts from various countries watched through live cameras.

Jing Jian felt the pressure again. He adjusted his mentality and announced: "The operation has begun."

Du Xingyu did not stay in the operating room so as not to disturb the surgeon. He was in the conference room, watching the proceedings via video.

After being prepared, Jing Jian's scalpel easily cut open the patient's body and began the kidney transplant!
