I opened a new book, I played live in the fairy world, everyone help collect it, and give some recommendations!

Xiao Feng had a smile on his face and spoke very humblely, but He Fangzhou could feel that this young man was not as easy to deal with as he seemed on the surface.

He asked this at this time, obviously wanting to know what he could do under him, and if he couldn't impress him next, it was hard to say whether he could stay.

Of course, he knew his recent reputation, and it was obvious that Xiao Feng on the other side was also a little worried about this, for fear that he was doing something that would be disagreeable to the world.

"Mr. Xiao, you should have heard of 3D printing technology, right?"

"Well, I know that. ”

In the first two years, all kinds of 3D printing boasted very fiercely, and there were many self-media who boasted about this technology as the source of the fourth generation of industrial revolution, but in the past two years, it has died down.

The reason is very simple, this thing is currently very limited, especially in the printing of metal materials, it is still too far behind, and the practicality is not strong.

"In the medical field, 3D printing technology has been very mature, and its counterparts in the United States have been at the forefront of the industry in this regard. In recent years, the University of Illinois in the United States has used 3D printing technology many times to print human blood vessels and transplant them into the human body. So this direction, in fact, is still very promising. ”

"But what is the intersection between this 3D printing technology and our Yurong base solution?"

Xiao Feng's face was full of curiosity, but He Fangzhou smiled slightly at this time, and then explained to Xiao Feng: "Actually, when I saw this Yurong base liquid, I had an idea... ”

At this time, all the researchers he brought sat up straight, because they all knew that their teachers liked to open their brains the most, and every time he opened his brains, he could indeed bring some new ideas and ideas.

"As you know, I used to be engaged in genetic medicine, and in recent years, the hottest thing in the field of genetic medicine is stem cells. Stem cells, you know, are the first evolutionary origins of every human being ... ”

He Fangzhou began to explain to Xiao Feng that the human body began to develop from a fertilized egg, and the next evolution of a fertilized egg is stem cells, and everyone develops from this simple stem cell.

The simplest cell, which can be said to be the source of all life, can be ever-changing, for example, DNA is a steel skeleton, and stem cells are the building material.

Under the framework of DNA, stem cells are slowly replicated, derived, filled, and finally developed into living people, which can be said to be the most basic raw materials for human growth and development.

In recent years, the concept of stem cells has been very popular, and many medical experts believe that this kind of thing is an important direction for the future development of human medicine, and it will be able to treat many incurable diseases that seem to be incurable.

For example, many people's internal organs, if they fail, can be rebuilt through stem cells, and there will be no rejection.

“。。。。。。。。 Now many scientists are studying the use of stem cells to rebuild human organs of scientific research projects, such as artificial hearts, artificial pancreas, artificial livers, etc., every year the world due to organ damage, failure and death of millions of patients, if scientists make a breakthrough in this area, it will definitely be an epoch-making event... ”

He Fangzhou talked endlessly in front of Xiao Feng, Xiao Feng listened very carefully, although he didn't understand the general direction He Fangzhou said, but he understood these artificial organ projects he said, indeed if a breakthrough is made in this area, then human beings will not be far from real immortality.

"Ahem... Teacher He, not to mention those far away, if you join our Ninth Laboratory, which direction do you want to choose as a breakthrough?"

Seeing that He Fangzhou was still talking like a river, Xiao Feng didn't have much time, continued to listen to his popular science, and directly interrupted him to ask.

Ma De, at the beginning, he and He Xiaojun just wanted to get the team behind He Fangzhou, who would have thought that after this guy came, he obviously didn't want to leave?

It seems that before, the plan to arrange for him to go to the ranch to raise mice was probably in vain, but now that he has new ideas, Xiao Feng is still very happy.

Anyway, when the time comes, he will separate He Fangzhou from his scientific research team, and the team will stay in the Ninth Laboratory, and under the leadership of He Xiaojun, they will conduct scientific research in accordance with the original four directions.

As for He Fangzhou, then throw it to the ranch and let him play, he can toss as much as he wants, and by the way, he can help cultivate some new people, as long as he doesn't get into trouble.

Xiao Feng already had his own thoughts in his heart, so he didn't plan to continue to fool around listening to He Fangzhou, and He Fangzhou's eyes were rolling at this time.

"Mr. Xiao, I want to use 3D printing technology, combined with Yurong base solution, and stem cell regeneration technology to develop artificial organ regeneration technology. And the first main direction of attack, is the artificial heart, at present, many international scientific research institutions are studying this, the earliest research in the United States, the most results, and even last year someone has made an artificial heart. But their artificial hearts are still flawed ... ”

Hearing He Fangzhou's thoughts, Xiao Feng was really stunned, artificial heart sounds very lofty? Seeing Xiao Feng stunned for a moment, and then with an interested expression, He Fangzhou hurriedly continued.

"Mr. Xiao, there are currently more than one billion heart disease patients in the world, and tens of millions of new heart disease patients are added every year. But there is one disease that does not work, and that is heart failure, which is irreversible. The only way to treat is heart exchange, and there are millions of patients who die of heart failure every year in the world, and hundreds of thousands of people are waiting for heart exchange surgery, so this is a big market. ”

He Fangzhou briefly introduced the purpose of his desire to make an artificial heart, Xiao Feng nodded when he heard it, okay, this guy is at least not the kind of madman who only thinks about scientific research and does not consider transformation.

If you can't make money in scientific research, then investors will definitely have no motivation, and the market that He Fangzhou described to him is indeed very interesting, he knows that this guy is not lying, because in Huaguo alone, there are tens of millions of people suffering from heart diseases.

"At present, the farthest thing in terms of artificial hearts is Johnson & Johnson's Texas R&D center, where they are researching the use of stem cells to create artificial hearts through 3D printing technology. Last year, they successfully printed an artificial heart, but the biggest problem at the moment is that the print is printed, but how can the heart be powered. We all know that the human heart is like a water pump, constantly pumping blood and bleeding to complete the circulation of blood in the human body. Previously, the artificial heart made by human beings was made of silica gel and titanium alloy, and a motor should be installed outside the human body, driven by a battery, to complete the heart's retraction and release action, and complete blood circulation. . . ”

He Fangzhou began to give Xiao Feng science about the current research and development progress of this artificial heart in the world, and Xiao Feng also listened to it with relish, and he wanted to know how He Fangzhou planned to use Yurong base liquid to build an artificial heart.

“。。。。。。 The artificial heart printed by 3D technology and using human stem cells as raw materials can be said to be 90 percent similar to the heart naturally born in the human body, but why can't it be applied in a large area? The problem still appears in the beating of the heart, to put it bluntly, it is an artificial heart, which will not beat like the heart that our human body grows itself. Why? It is because of the lack of ligament material when printing, to put it bluntly, to make a car engine, you can already build a cylinder, but you can't find the crankshaft, without the crankshaft, you can't drive the power out? ligaments, fascia, so that the connective tissue is the key to the heart beating, how much blood is drawn in each beat, how much blood is released, how many times a minute beats, this is the most critical problem that the artificial heart is currently facing. The people of the United States have not been able to find suitable materials to print the ligaments and fascia needed in the heart... And this collagen that you found here today, I think that's the key to solving this puzzle... ”

Listening to He Fangzhou talk about this, Xiao Feng suddenly realized, He Xiaojun had given him science popularization before, this collagen is a very important supplement for the human body, it is an important part of human muscles, ligamentous fascia, connective tissue, and even an absolute component.

And he didn't expect that this thing would have such an important role in the field of artificial hearts.

“。。。。。。。 Therefore, as long as I can effectively combine 3D printing technology with stem cells and this collagen, I can make an artificial heart that is truly suitable for human beings, and the future is not only artificial heart, but also artificial lungs, artificial livers, and even as long as we want, we can change a person from head to toe. ”

Damn, how did you rise to such a height? It's already in the field of regenerative medicine?

He Fangzhou said in the end, he was excited, as if he couldn't see a golden avenue in front of him, and almost all the people who knew biochemistry and medicine were excited and their faces were blushing and their necks were thick, indeed the stem cells and the collagen molecules are definitely the two golden keys to overcome the problem of regenerative medicine!

And at this time, He Xiaojun was also completely convinced, he was really a real master, not only did he start from a higher starting point than him, but he also saw farther than him, such a person could not be convinced!
