The start of science and technology

Before his laboratory, Du Xingyu temporarily joined the team of Xie Ziyu to carry out stem cell cultivation and induction techniques.

Simply, stem cells are a class of cells with unlimited or eternal self-renewal capabilities, which can produce at least one type, highly differentiated sub-cell. It is mainly divided into all-in-capacity cells, multi-capable cells and monovoltaic stem cells.

All-in-range stem cells have the potential to differentiate into a complete individual. For example, Du Xingyu has a cloning, it is to write the gene information of the good Dragon, artificially induce all-around stem cells, then cultivate it into embryo.

Multi-capable cells have the ability to produce a variety of cells, but they cannot develop themselves.

Single-capable stem cells can only produce a type of cell.

This time they research direction, mainly multi-capable cells and single-capable cells.

Thanks to the team research project of Xie Zizhen, it is to use stem cell cultivation and induction technology to cultivate people's epithelial cell layers.

The goal proposed by Du Xingyu is to cultivate the human body in vitro. Both don't know how much it is.

"Establish an external organ culture project." Du Xingyu simulates new projects on the technology simulator.

It is also a very complicated thing that wants to cultivate the human organs without "cloning" people.

Du Xingyu is doing first, and the research data of Peking University's database and hospitals will be entered into the technology simulator to obtain the necessary information.

Science and technology simulator: "Research progress, 30%."

"Every organ requires different cultivation methods." Du Xingyu shrunk the target and decided to start with a human organ.

"According to the data, the kidney is the most manified organ transplant, but also the most needed organs." Du Xingyu thought a little, and made a decision: "It will start the kidneys from vitro!"

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

He needs to chase the source, find a stem cell that can develop a kidney, and study all the conditions needed for kidney development, step by step from the beginning.

......

"You said, cultivate the kidneys in vitro? I admit that Du Xingyu is indeed very visible in stem cell cultivation technology. But this goal is not a matter of doing things?" In the period of cooperation with Du Xingyu, the cell expert, medical expert in the team Still some doubts.

"Yeah, I originally studying to cultivate the epithelial cell. Now it's hard to improve so much. I can't see the head at all!" A group member shook his head, "Hey, it is really a headache, I don't know what Director thinks, let Let's listen to him. "

"Who knows ... Originally, our project is a plan for the cultivation research of in vitro organs with the island, South Korea and the Netherlands. Now the island, South Korea, the Netherlands and France have made good progress. We are not progressing now, etc. At the time, the shame was lost. "A cell expert worried.

Their project is part of the "Cell Biology Research Program" jointly carried out by five top medical research institutions in five countries. At that time, the parties will conduct academic exchanges, or if there is no result, it is the loss of the face to abroad.

"I see this young man is because of the clone tyrant, it is quprofed, it is a bit too floating!" A old expert said, "When he fell a few times, he understood, scientific research, but not relying on his mouth. ! "

......

"Two months fails." After two months, Du Xingyu has completed the process of simulating in vitro cultivating organs, but the human physiological mechanism is too complicated, and multiple simulations have failed.

"Stem cell induction I have completed, the most difficult still, how to ensure normal development and survival of in vitro," This makes Du Xingyu some headaches.

"Maybe I should redesign an ergonomic system. Simulation Each organ or even the role and physiological response of each cell in the human body, and then then according to these simulated an 'in vitro kidney culture dish'."

"It is recommended to open the biological observation function." Science and Technology simulator reminds, "consumes 10 million energy points to open the biological observation function, you can obtain more detailed information, more detailed in the biological instrument observation of the world human beings. "

"Is there this function?" Du Xingyu surprised, "How to use?"

Ten thousand energy points, Du Xingyu has already owned, the last time cloned Wanglong's hot, let him accumulate a lot of energy points.

After consuming 10 million energy points, the new feature is open.

SBSTA reminded: "The biological observation function is to open the four-dimensional view of the three-dimensional biopsy, you can get the most comprehensive information. I can record this information, but your brain can't accept so many information, so I can only see three seconds. "

"Start!" Du Xingyu is also very curious, watching the living body from the four-dimensional perspective, what experience is,

"Target choice, your own body, open high-dimensional view observation!" The technology simulator finished, Du Xingyu saw a new one.

If it is a normal human being seen in the three-dimensional world, seeing a three-dimensional image. The angle of view is a three-dimensional picture that is inherently.

And in the four-dimensional perspective, Du Xingyu's sight can actually "through" his body!

He can see every "three-dimensional noodles" of his body, just like starting full angle! The perspective can see the body from the outside, or you can see the body from the body.

Each of his organs, each blood vessel and cells have no objection to the four-dimensional perspective.

It is like the inside of his body, and there is countless double-eyed, and watch himself. Massive information instantly poured into his brain, Du Xingyu felt the brain swelling, he could not bear more information.

Other technology simulator even if it cuts off four-dimensional perspective, he will definitely be coma.

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

"Call!" Du Xingyu has not returned from the scene from the picture, all three-dimensional objects and creatures, almost no secrets of all three-dimensional objects!

He slowly said: "Continue!"

......

After the conditions required for human kidney development, the design of the kidney culture dish is easier.

Du Xingyu has made several simulations and finally got a successful result.

It is now possible to start experimenting in the real world.

......

"According to my research, I have roughly understand the technical point of the body's technology." At the meeting of the research team, Du Xingyu said: "I think it is time to start experimentation."

"You already understand?" Xie Ziyu was a little surprised. During this time, Du Xingyu has been collecting various information. It seems that it is not to study, but to learn.

"Yes." Du Xingyu nodded.

The team members do not move, but they don't think about it.

Du Xingyu continued: "You can start the mouse to cultivate trials."

He wants to carry out human organs directly, but before the mouse test is successful, it is obvious that the hospital will not promise directly to start the human organ test.

"Of course," Xie Ziqi did not refuse, mouse trials, he loves it. "

By now, Xie Ziyi believes that the role of Du Xingyu has reached the team, and Du Xingyu proposed stem cell culture technology has made them make great progress in the cultivation of epithelial cells.

As for the cultivation of in vitro kidneys, Du Xingyu loves to toss and toss it. Anyway, the test of mice is more.

Du Xingyu has begun to act because he has been in the technology simulator, and his progress is very smooth.

A adult mouse can develop mature for 30 days, and Du Xingyu has chosen a group of mice to produce mouse renal cultivation units. Then, their stem cells are extracted, and induction.

Next, the development of kidneys outside the mice is observed daily.

At the beginning, the members of the research team were seeing novelty, no one really thought that Du Xingyu can succeed.

However, only a few days later, their attitude had a large change of 180 degrees.

In mouse kidney cultivating equipment, stem cells in mice really started differentiation to kidney!

The person who started to discover is a cytological expert named Di Wu.

He is also one of the people who have become impossible to cultivate in vitro kidneys in Du Xingyu. Di Wu privacy said with colleagues, "in vitro kidney cultivated, within 30 years, even within 50 years, there is no success may!"

"Human kidney, how can it be normal in vitro? Unless he cloned a person! Now the law is not allowed!"

It is said that the mouse kidney cultivation device designed by Di Di Di Dudu is still quite curious. I always want to know how it can replace the mouse body structure, let the kidney make a good development and exercise.

Therefore, there is time, Di Wu goes to "pay attention" this institution, observing the development of cells inside.

On this day, Di Wuzhi was observed to observe cell growth. He was surprised to find that the original mouse stem cells have begun to differentiate into kidney-related cells!

"Actually differentiated?" Di Jingwu was shocked, "Not a single cell tissue, but the prototype of various cells in the kidney!"

"Don't he really do it?"

Di Wu is incredible, he immediately called Xie Ziqi, saying: "Director, big things!"

"Ah?" Di Wu's words, Xie Ziyu, "said the hospital?"

"No, it is a laboratory!" Di Wu rushed, "I just went to observe the cultivation device of Du Xingyu. What do you see?"

"What? Old Di, why do you like to hang appetite now?" Xie Ziyu is not speaking.

"I observed that he induced mouse stem cells, has begun to differentiate into liver organs! And these cells are active, and they can continue to develop!" Di Wu said.

"What? Really differentiated?" Xie Zi was shocked, "You are waiting, I will come here right away!"
