The Start Of Technology Live Broadcast To Build Rockets

Before the completion of his laboratory, Du Xingyu temporarily joined Xie Ziqian's team to conduct research on stem cell cultivation and induction technology.

Simply put, a stem cell is a type of cell with unlimited or immortal self-renewal capacity, capable of producing at least one type of highly differentiated progeny cells. It is mainly divided into totipotent stem cells, pluripotent stem cells and unipotent stem cells.

Pluripotent stem cells have the potential to differentiate into complete individuals. For example, Du Xingyu's previous cloning of Tyrannosaurus rex was to compile the genetic information of Tyrannosaurus rex, artificially induce pluripotent stem cells, and then cultivate them into embryos.

Pluripotent stem cells have the ability to produce a variety of cells, but they cannot develop into individuals.

Unipotent stem cells can only produce one type of cell.

This time their research direction is mainly pluripotent stem cells and unipotent stem cells.

Xie Ziqian's team research project is to use stem cell cultivation and induction technology to cultivate the human epithelial cell layer.

The goal proposed by Du Xingyu is to directly cultivate large human organs in vitro. The difference between the two is not known.

"Establish an in vitro organ cultivation project." Du Xingyu simulates a new project on a science and technology simulator.

It is also a very complicated matter to cultivate human organs alone without "cloning" people.

The first thing Du Xingyu did was to enter Peking University's database and hospital research data into the science and technology simulator to obtain the necessary information.

Science and Technology Simulator: "Research progress, 30%."

"Each organ requires a different cultivation method." Du Xingyu narrowed his goal and decided to start with a human organ.

"According to data, the kidney is the most transplanted organ in all human beings, and it is also the organ most in need." Du Xingyu thought for a while and made a decision: "Then start by growing the kidney in vitro!"

Du Xingyu started to build a human kidney model on the technology simulator.

He needs to go back to the source, find the stem cells that can develop into the kidney, study all the conditions needed for kidney development, and start from scratch step by step.

...

"You said, cultivating kidneys in vitro? I admit that Du Xingyu is indeed very insightful in stem cell cultivation technology. But this goal, isn't this making trouble?" During the period of cooperation with Du Xingyu, the cell experts and medical experts in the team Still some doubts.

"Yes, originally we were going to study and cultivate epithelial cells. Now that the difficulty has increased so much, we can't see the head at all!" A team member shook his head, "Hey, it's a headache. I don't know what the director thinks We listen to him."

"Who knows... Originally our project was an in vitro organ breeding research project carried out with the island countries, South Korea, and the Netherlands. Now the island countries, South Korea, the Netherlands and France have all made good progress. We are not making any progress now. Wait for the exchange meeting. When the time comes, that shame is too big.” A cell expert worried.

Their project is part of the "Cell Biology Research Project" jointly launched by five top medical research institutions in five countries. At that time, all parties will have academic exchanges. If nothing has been achieved, it will be embarrassing to go abroad.

"I think this young man was praised because he cloned Tyrannosaurus rex. It's a bit too ridiculous!" said an old expert. "After he fell a few times, he would understand that scientific research is not based on lip service. !"

...

"The eighth cultivation failed." Two months later, Du Xingyu had completed the process of cultivating organs in vitro, but the physiological mechanism of the human body was so complicated that many simulations failed.

"I have completed the induction of stem cells. The most difficult thing is how to ensure the normal development and survival of organs outside the body." This gave Du Xingyu a headache.

"Maybe I should redesign a human body simulation system. Simulate the role and physiological response of each organ and even each cell in the human body, and then simulate an'in vitro kidney culture dish' based on these."

"It is recommended to turn on the biological observation function." The science and technology simulator reminded, "When you consume 10 million energy points to turn on the biological observation function, you can obtain more detailed information than the biological instruments that humans have in this world. "

"Is there still this function?" Du Xingyu asked in surprise, "How to use it?"

Du Xingyu already had 10 million energy points, and the popularity of cloning Tyrannosaurus last time allowed him to accumulate a lot of energy points.

After consuming 10 million energy points, the new function is activated.(Read more @ hotmtlnovel.xyz)

The science and technology simulator reminded: "The biological observation function is to open a four-dimensional perspective to observe three-dimensional creatures, and you can get the most comprehensive information. I can record this information, but your brain cannot accept so much information, so you can only watch it for three seconds. ."

"Let's get started!" Du Xingyu was also curious, what kind of experience it is to watch organisms from a four-dimensional perspective.

"Goal selection, your own body, open high-dimensional observation!" After the technology simulator, Du Xingyu saw a brand new self.

If a normal human looks at him in a three-dimensional world, what he sees is one side of a three-dimensional image. The angle of view is a three-dimensional picture transformed from within.

From a four-dimensional perspective, Du Xingyu's line of sight can actually "cross" his body!

He can see every "three-dimensional face" of his body, as if starting a full-angle perspective! The angle of view can be seen from outside the body, and it can also be seen from the inside of the body.

Every one of his organs, every blood vessel and cell are exposed to the four-dimensional perspective without any concealment.

It's like having countless pairs of eyes inside his body, looking at himself at the same time. A huge amount of information poured into his brain instantly, and Du Xingyu felt his brain swell, and he couldn't bear this much information.

Fortunately, even if the technology simulator cuts off the four-dimensional perspective, he will definitely pass out.

"The biological information has been recorded." The technology simulator said, "The external conditions required for the development and growth of the human kidney can now be embodied."

"Huh!" Du Xingyu hasn't recovered from the picture just now. From the high-dimensional perspective, all three-dimensional objects and creatures have almost no secrets!

He slowed down for a while before he said, "Go on!"

...

After knowing the conditions required for human kidney development, it is much easier to design an in vitro kidney culture dish.

Du Xingyu conducted several simulations and finally got a successful result.

Now you can start experimenting in the real world.

...

"Based on my research in the past few months, I have roughly understood the technical points of in vitro organ cultivation." At the research team meeting, Du Xingyu said: "I think it's time to start experiments.

"You already understand?" Xie Ziqian was a little surprised. Du Xingyu had been collecting various information during this period. It seems that it is not here to study, but to learn.

"Yes." Du Xingyu nodded.

The team members were calm on the surface, but they didn't agree with them in their hearts.

Du Xingyu continued: "You can start the mouse breeding experiment first."

He wants to directly cultivate human organs, but before the mouse experiment is successful, obviously the hospital will not agree to directly start the human organ experiment.

"Of course you can." Xie Ziqian did not refuse, as he did the mouse experiment as he pleased.

So far, Xie Ziqian believes that the role of letting Du Xingyu join the team has been achieved. The stem cell culture technology proposed by Du Xingyu has enabled them to make great progress in the cultivation of epithelial cells.

As for the in vitro kidney cultivation, Du Xingyu likes to toss and go.

Du Xingyu started to act, because he had already done it once on the technology simulator, and his progress was very smooth.

An adult mouse can mature in 30 days. Du Xingyu selected a group of mice to create an in vitro culture device for mouse kidneys. Then extract their stem cells and induce them.

The next step is to observe the development of the mouse's kidneys in vitro every day.

In the first few days, the members of the research team all regarded it as a novelty, and no one would really think that Du Xingyu's experiment would be successful.

However, only a few days later, their attitude changed a hundred and eighty degrees.

In the mouse kidney in vitro culture device, mouse stem cells actually began to differentiate into the kidney!

The first person discovered was a cytology expert named Di Jingwu.

He was also one of the people who thought Du Xingyu’s in vitro kidney cultivation could not be successful. Di Jingwu told his colleagues in private, “In vitro kidney cultivation has not been successful in 30 years, or even 50 years. may!"

"How can a human kidney grow normally outside of the body? Unless he clones a person! Now the law doesn't allow it!"

To conclude, Di Jingwu is quite curious about the mouse kidney cultivation device designed by Du Xingyu, and always wants to know how it can replace the mouse body structure, so that the kidney can develop and perform its functions intact.

So when he had time, Di Jingwu went to "pay attention" to this institution to observe the cell development in it.

On this day, Di Jingwu went to observe cell growth as usual. He was surprised to find that the original mouse stem cells had begun to differentiate into kidney-related cells!

"It's really differentiated?" Di Jingwu was shocked. "It's not a single cell tissue, but the rudiments of various cells in the kidney. They all appeared!"

"Can he really do it?"

Di Jingwu felt incredible. He immediately called Xie Ziqian and said, "Director, something has happened!"

"Huh?" Xie Ziqian was startled when Di Jingwu said, "What happened to the hospital?"

"No, it's a laboratory!" Di Jingwu said quickly, "I just went to observe Du Xingyu's cultivation device. Guess what I saw?"

"See what? Old Di, why do you like to hang people when you talk now?" Xie Ziqian said silently.

"I observed that the mouse stem cells he induced have begun to differentiate into liver organs! And these cells are full of activity, and they seem to be able to continue to develop!" Di Jingwu said.

"What? Really divided?" Xie Ziqian was shocked, "You wait, I'll come over right away!"
