Huang Fan discovered a problem that Pang Pang and Hai had previously ignored, or a phenomenon that had not been discovered due to insufficient experimental data.
Among biological cells, in addition to those that are constantly dividing, there are also brain cells and cardiac muscle cells that do not divide.
Since cells cannot divide, the source of life has no effect on brain cells and cardiac muscle cells.
Although it benefits from the "youthful vitality" of other cells, brain cells and heart muscle cells also receive many benefits, extending their life span by 20 to 30%.
It's just that this improvement ratio can't keep up with the improvement of other cells.
The wooden board that determines the amount of water in a barrel is not the longest one, but the shortest one.
The same goes for the lifespan of living things. No matter how long other cells in the body can live, if the lifespan of brain cells, the key cells, is not long, the living body can only be brain-dead.
Pang Hai and Honda Masami, who did not notice this problem at first, also felt very strange.
Logically speaking, if the life essence cannot increase the life span of brain cells and heart muscle cells, it means that animals that eat the source fruit will not have their life span extended by two or three times.
However, the reality is exactly the opposite. The animals on Yongri Island that ate the fruit have all experienced an increase in lifespan, and the longest increase was 2.8 times. Those animals did not suffer from brain death or heart failure.
This situation is contrary to the experimental results.
In this case, it can only mean that there are other things affecting the lifespan of these animals.
Huang Fan and Pang Panghai re-analyzed the composition of Yuanguo pulp, but found nothing.
Until Jiang Zhiren reminded me that the answer might be in the core of the fruit.
Suddenly enlightened, Huang Fan and others looked at the animals and discovered a pattern. Among the animals whose lifespans were extended, the lifespans of small and medium-sized animals generally did not increase significantly.
The animals whose life spans have been significantly increased are those of large size. The characteristic of these animals is that they can swallow fist-sized source fruits in one bite.
This shows that these animals swallowed the fruit core together.
…
Cut open the purple core of a Yuan fruit. The inside of the core is similar to the kernel of a pecan. Pang Panghai listed all the ingredients of the core and kernel.
First, some of the components that are the same as Blue Star organisms are eliminated, and the remaining components are separated by them.
After some experiments, they narrowed the scope to three types, and then through in vivo injection experiments, they finally identified the substance.
This is an organic compound extracted from nuts. This organic compound is called "cytoactivin".
Among animals injected with this cytokine, young and adult animals had almost no effect. But in old animals, the situation was completely different.
Cytokinins entering the elderly body will activate the division mechanism of brain cells and cardiomyocytes, causing brain cells and cardiomyocytes to divide into new cells.
This is equivalent to the brain and heart being reborn, especially with the cooperation of the source of life, the brain and heart can divide new cells almost without damage.
"It's a pity that cytoactivins are also resistant to resistance." Huang Fan sighed.
Jiang Zhiren shook his head and said with a smile: "Don't be too greedy. It's better to eat one bite at a time."
Huang Fan, who was mentally exhausted, was stunned for a moment, then relaxed and said, "It's me who is possessed by the devil."
Cytokinins can only stimulate those cells that cannot divide, thereby temporarily opening the division restrictions of these cells.
Huang Fan calls this process "temporary cancerization" because brain cells and cardiomyocytes stimulated by cytokines will behave like cancer cells whose restrictors have been released.
It's just that cytokines temporarily release the limiter, while cancer cells permanently release the limiter.
…
As for the source of life, research on cytokines is progressing rapidly.
Not only the efficacy, dosage, side effects, and drug resistance of the two compounds are studied, but also the industrial synthesis process.
If the source of life, cytoactivin, can really act on the human body, the more than 3,000 trees on Yongri Island alone will not be able to meet the needs of new humans, and industrial synthesis processes must be sought.
Research is progressing very quickly, with hundreds of thousands of animal experiments alone being done.
A life potion prepared from the essence of life, and a regeneration potion prepared from cytoactivin. The rebirth potion has obvious side effects, and will cause memory loss in the brain after injection.
This is a difficult problem to solve. Brain cells themselves store a large amount of information. During the process of cell division, information is lost. This is a very normal situation.
Huang Fan and the others could only choose a compromise plan, which was to back up the memory through a biological computer, complete the regeneration of brain cells, and then re-inject consciousness and memory into the brain.
…
Inside the biochemical laboratory of the Hulk Observatory.
Jiang Zhiren hurriedly walked to Huang Fan and handed over a document:
"good news."
After taking a look at the document, Huang Fan stopped what he was doing: "The Science and Technology Commission approved it so quickly."
Jiang Zhiren explained: "There is no way. Our other technologies are advancing by leaps and bounds, but there is still no good news about life science and technology. Now it is probably to boost people's hearts!"
"Then let's prepare for the first phase of clinical work as soon as possible." Huang Fan ordered while the iron was hot.
"No problem." Jiang Zhiren nodded.
Just when he was about to go out, Pang Panghai stepped into the laboratory. Jiang Zhiren was curious and asked: "Why is the experiment not going well with a sad face?"
"It was very unsatisfactory." Pang Panghai said helplessly and handed an experimental report to Huang Fan.
After looking through the experimental data, Huang Fan frowned and asked in surprise: "There is no way to synthesize the source of life."
Pang Dahai spread his hands and sighed: "No matter whether it is chemical synthesis or the forced splicing of nano-robots, there is no way to synthesize it."
In the experimental report, the nanorobot splicing method, which had always been successful before, did not work for the first time.
There are only 1566 atoms that make up the source of life. Even if it is forcibly pieced together, all the elements will be exactly the same. As soon as the nanorobot is released from the spliced state, the molecular structure will automatically collapse.
"It's going to be difficult now." Huang Fan had a headache.
The source of life is different from cytoactivin. The source of life can solidify biological age, while cytoactivin only has an effect on those old people whose brain cells are in the final stage.
In addition, cytokines can also treat Alzheimer's disease and have no other applications.
The life essence is something that most people need, except for minors, who cannot use the life essence because their bodies are not fully developed.
Jiang Naoren thought for a while and suggested: "Since artificial synthesis is not possible for the time being, let's try cloning..."
"I tried it, but it didn't work." Pang Panghai scratched his head and replied.
"Listen to me." Jiang Naoren knew that Guozi might not be able to be directly cloned:
"What I mean is to clone the source tree and then simulate the living environment for semi-natural production."
After thinking for a while, Pang Panghai understood that this was the best way now. Before there was no solution to artificial synthesis, he would first carry out semi-natural cultivation.
Huang Fan also agrees with this plan. We still need to be flexible when doing things, and we can't just stick to it.
Pang Panghai, who had not taken over the synthesis of life essence, took over this matter: "Leave it to me to cultivate the source tree!"
"Yes! Okay." Huang Fan had no objection. Anyway, he was busy with the first clinical phase recently.
