That evening, Li Sheng and Zhang Dingbian returned to the farm from Manaus. Pen & Fun & Pavilion www.biquge.info

The next morning, as soon as Li Sheng arrived at the office, Zhang Feng came over and told him about the police coming to investigate the case. In fact, they came to make a record or something, and Li Sheng didn't expect them to catch the thief.

Zhang Feng said some more work on the farm, and then left.

Not long after he left, Feng Xiaoting, who was too busy to leave the laboratory, suddenly came to him.

Li Sheng saw him lock the office door, and knew that he had something important to say to himself, and asked him, "Stone frog?" ”

Feng Xiaoting said with a trace of irrepressible excitement on his face: "Yes, boss. After testing, we can not only preliminarily determine that the blood of the stone frog has substances that accelerate the metabolism of animal cells, but also find a very peculiar phenomenon in them! ”

Feng Xiaoting is an absolute scholar, although he is not a paralyzed face, but his usual expression can be said to be the kind of Taishan who collapses in front of him and does not change his face. Now that he saw the excited look on his face, Li Sheng couldn't help but feel some curiosity: "What phenomenon?" ”

"Limb reborn. There is also the rebirth of internal organs. Feng Xiaoting's voice was suppressed with excitement. As long as the stone frog does not die, its limbs or some tissue on its body are mutilated, and it can slowly grow back. ”

Li Sheng also felt strange when he heard it. There are indeed some other manifestations in the animal kingdom, such as sea cucumbers can spit out their intestines for predators to eat, and after escaping, they can still grow a new pair of intestines, or starfish, after cutting the starfish into several pieces, each starfish will become a new individual.

It is said that if an earthworm can be cut into two pieces in a certain proportion, both ends can become new individuals, and even if the proportion is not right, the long one can grow into a normal earthworm again. In addition, geckos with broken tails to survive are also this kind of appearance.

He hadn't heard of frogs having that ability

But he didn't think there was anything to be excited about, at most it was the discovery of a new animal with this ability. He nodded, "So, you've discovered a new species. "But he's also talking nonsense, that kind of stone frog and some plants found in Xiangxi are originally not available in this world, what else can they be if they are not new species?

When Feng Xiaoting heard him say this, the excitement in his heart was also accepted. Only then did he remember that the boss in front of him was not a researcher. He laughed and said, "Boss." That's not the point. Rather, we find a very special cell in this stone frog. ”

He paused, then said, "The boss should have heard that if a person's liver is cut off, it will still survive and grow back. ”

Li Sheng nodded. Although it was a medical thing, he knew it. After all, it's not uncommon to hear about liver transplants on the news.

Feng Xiaoting poured himself a glass of water and drank two sips before sitting down and continuing: "The human body's liver will automatically recover after loss, in fact, although the mechanism is somewhat different from the rebirth of a severed limb, the principle is similar. It's all the function of memory T cells. ”

He explained the so-called T cells. It turns out that T cells are cells that can carry genetic information, and when this cell divides, the defective parts of the animal's body will be restored to the appearance determined by the genetic information.

After a pause, he continued: "According to our human research on animals, the lower the animal, the more active the memory T cells. And the kind of stone frog you provided, the tissue cells that were removed without injury are all normal cells. But as long as the frog survives, the cells near the wound will turn into T cells, allowing the tissue to return to its original state. ”

Li Sheng finally understood, but he didn't understand what it was: "But what if the ability of the stone frog is studied?" ”

Feng Xiaoting said with a smile: "If it is the stone frog cell itself, it has that ability, it is nothing. However, we found that if the serum of the stone frog was injected into the white mouse, the white mouse also had the ability to regenerate from a severed limb. At the same time, it was also found that some cells of the mice had changed. It has T cell properties. ”

As soon as Li Sheng heard this, he stood up suddenly, propped his hands on his desk and asked him, "You mean, the stone frog has a limb rebirth because of its serum?" ”

"Maybe its cells are better suited to that substance, so the stone frog survives, and the rat grows a little bit slower than the severed foot within a few days. But what is certain is that the serum of the stone frog does activate the activity of the T cells that the animal has been hiding all along. It's just that we don't know what this active substance is, and in the experiments on white mice, there have also been some side effects. Most of the experimental mice have died. ”

The expression on Li Sheng's face was a little strange, he had been trying to find something irreplaceable from the space recently. But I didn't expect that he had already found it.

But he soon realized that now was not the time to be happy: "So now have you found out what substance is working?" ”

"It's not what we find, it's the cells that choose for themselves." Feng Xiaoting said with a smile. "We found that when normal cells are transformed into T cells, there are several more substances in the cells. So we extracted this substance, and later we found that this substance alone can achieve the same experimental effect. ”

He said with pity in his tone: "It's just that whether it is directly injected with serum or using extracts, the internal organs of experimental mice will have varying degrees of failure. We speculate that this is because after the T cells are activated, the nutrients accumulated by the animals are consumed by the T cells. But in any case, this new discovery can definitely shock the medical community. ”

Li Sheng thought the same way. If that thing does prove to be effective for the human body, the world's medical system may have to undergo a subversive change.

It is conceivable that the kind of substance they extracted from the stone frog can be used in clinical practice, and most of the non-congenital disabled people can almost have a chance to return to their normal bodies, and seriously injured people, as long as they can survive for a period of time, may be able to use this substance to directly repair their bodies without dying. Of course, according to the mechanism of T cells, people who have undergone plastic surgery are not suitable for use.

Li Sheng sat down slowly and asked Feng Xiaoting, "How many people know about this experiment?" Can they keep it a secret? ”

When Feng Xiaoting heard his question, the smile on his face was put away: "The people in the laboratory who know this result are me, a cytology expert and two experimenters. ”

Li Sheng stared into his eyes and asked, "Do you think they can be trusted?" If it's credible, I'll continue to involve them in the experiment, and if not, I can contact Huaxia and ask Huaxia to bring people back. ”

"But if they let them leave, Huaxia will definitely know the news."

Li Sheng smiled and said, "I can't stop talking." "Since you can't be ruthless, the news leak is a sure thing." And Huaxia is thousands of miles away, even if he gets the news, it is more likely to seek cooperation rather than snatch this thing. ”

Feng Xiaoting will understand that the credibility of what Li Sheng said refers to whether those researchers will leak information to countries or people outside of China. He is still confident in this: "I think they may report to Huaxia. But it should not be leaked to other forces. Huaxia attaches great importance to the research project I have proposed before. The researchers they send should all be trustworthy. ”

Li Sheng thought about it, as if it was indeed like that. He nodded and said, "That's for the best." If it is not necessary to study the stone frog, do not involve more people. Now the people involved, you go back and talk to them. It's impossible to give them the results of this research, but after the research is done, I can give some monetary compensation. They can stay on the farm if they want to, and if they don't, I'll let them go. ”

Feng Xiaoting knew the application prospect of the substance on the stone frog. That's a very lucrative industry. And their so-called research was not actually thought of by themselves, but Li Sheng gave hints and provided raw materials. With these two things, anyone with a certain amount of expertise can study them.

These people are on this project, and everything is going to be natural, that is, it takes some time and energy. In this study, they are no different from ordinary migrant workers. It's okay to get fame and fortune on this project. But greed is a little wrong.

Feng Xiaoting didn't know what other people would think, but he himself didn't think about fighting for interests that didn't belong to him in this project. He nodded and said, "I'll relay your words to them when I get back." ”

Li Sheng thought for a moment and said, "I hope you will give priority to this project." If there is anything needed, I will try to meet it. ”

Feng Xiaoting really didn't intend to be polite when he heard this: "Now we need more stone frogs." ”

Of course, Li Sheng will not refuse this request: "I'm sending a hundred of them tomorrow." Is it enough? ”

"That's enough for now." Feng Xiaoting said with a smile. "Oh, there's good news. The fungus-infected bug you sent last time had almost the same composition as Cordyceps. ”

As he spoke, he took out two reports from his file bag and handed one of them to Li Sheng: "This is the composition analysis of insects." The proportion of Cordyceps polysaccharides, cordycepin and other substances is higher than that of wild Cordyceps sinensis produced in China. There are no substances harmful to the human body. It can be used as cordyceps. ”

After speaking, you handed another one to Li Sheng and said, "This is an analysis report of another kind of leaf." It does contain some chemicals that we don't know about, and it can accelerate the secretion of gonadal hormones, adrenal glands and hormones in test animals. However, other effects and side effects on humans need to be further studied. ”

Both reports are really good news. Since the cordyceps fungus has the same composition as cordyceps, it also represents the value of artificial domestication. Although the technology of domestication is not yet known, there is at least one premise.

Cordyceps is formed when the larvae of a certain type of moth are infected with a certain fungus. In order to be cultivated artificially, it is necessary to collect the eggs of the moth and the spores of the fungus. And now he doesn't know what it is, let alone how to collect it. Perhaps this also requires the help of laboratories.

Now it seems that in order to keep Feng Xiaoting on the farm, he invested nearly 300 million US dollars to build this laboratory. That would probably be his most fortunate investment. (To be continued.) )
