The Technology Tree of Xueba

March 10. Zhou Yu convened a biological meeting of the Science and Technology Committee to address the problems discovered by the astronauts.

Members of the Science and Technology Committee, Wang Xiaoxiao, director of the Gene Research Institute, and Tao Shengwen, director of the Cell Laboratory, participated in the meeting.

Chen Jin, an expert in neurology, Qi Zheng, an expert in traditional Chinese medicine, and Zhao Tianyuan, an expert in internal medicine.

Zhou Yu was the first to make a speech: If you find a problem, you have to solve it. We found that astronauts living in space will have many sub-health problems within half a year.

If you want to survive on other planets for a long time, you must strengthen the adaptability of the human body to the environment.

With our current technology, we can only choose between genetic modification of the human body or cell modification.

The method of genetic modification is to change a person's genetic material so that it expresses certain proteins with special functions.

Cell transformation is to make human cells stronger by quenching cells, so as to achieve the purpose of strengthening the adaptability of the human body.

Qi Zheng, an expert in traditional Chinese medicine, immediately objected with a clear-cut stand: I strongly oppose the way of genetic modification, we cannot allow foreign genes to slander our human gene pool.

Some evil scientists have genetically modified babies.

She was only changed by one genetic locus, which could have extremely terrible consequences.

This altered gene is likely to produce a new genetic disease, contaminating our entire human gene pool.

Inherited diseases such as hemophilia and albinism are all genetic mutations at a certain gene locus. At that time, it may only be a mutation in a person's gene.

It spread through human reproduction, turning this disease into a more widespread disease.

This is just a change in one genetic locus. If the human body is genetically modified, thousands of genetic loci will be changed, and it is unknown what terrible consequences it will cause.

It may even be because of our decision that the gene pool of the human population has undergone major changes directly, and it is unknown what kind of terrible chain reaction it will produce.

One bottle is not full, half the bottle is rattling. After reading some popular science articles, I thought I had grasped the truth.

This kind of person is described as a person like Dr. Xiang Qi. Wang Xiaoxiao waited politely until Qi Zheng finished speaking, and he immediately replied.

It's like we use gene editing to solve hemophilia, which has plagued human beings for many years.

It modifies the patient's gene, corrects the defective part of the patient's gene, and retransmits the hematopoietic stem cells formed with this intact gene into the patient's bone marrow.

This method can effectively cure the genetic disease of hemophilia.

But whether the probability of having a child with hemophilia in a hemophilia patient cured by this method changes.

The answer I give is no change, because we only change the genes of the somatic cells, not the genes of the germ cells.

For this kind of genetic modification that has been verified to be correct and can solve diseases, we did not modify germ cells, but chose to modify somatic cells.

We use gene editing tools cautiously to prevent the balance of human genes from being changed due to our self-conceived methods, thereby polluting the entire human gene pool.

The genetic modification to enhance the adaptability of the human body must be to modify the somatic cells of normal people, and we will never touch the taboo of human germ cells.

Our genetic research institute has been studying the ability of certain gene fragments, and found many protein structures with special functions.

I want to find some functional proteins that have a positive effect on the human body without causing side effects on the human body.

From a scientific point of view, it is still feasible.

After Qi Zheng heard Wang Xiaoxiao finish speaking, he immediately apologized and said: This is my mistake. I didn't know at all. There is also a way to genetically modify human cells without affecting the genetic material of offspring.

Chen Jin also agreed: Somatic cell genetic modification is indeed a more feasible method.

Through functional proteins expressed by special genes, it can completely change the state of the human body.

As long as it is confirmed that this protein will not cause side effects to the human body, we can still accept this level of genetic modification.

Our human body has been injected with many foreign proteins since birth, most of which are various vaccines and antibodies.

Protein is also one of the commonly used drugs in medical treatment now, and people's acceptance of this kind of thing is still very high.

Zhou Yu said with a smile: After Director Wang Xiaoxiao's introduction, everyone has a high degree of acceptance of genetic modification.

Next, please invite Director Tao Shengwen to introduce the basic idea of ​​cell transformation, and let's listen to another path that can be realized.

Tao Shengwen said with a serious expression: Let me introduce the method of cell transformation.

We all know that a person who exercises for a long time is definitely healthier than an otaku who stays at home for a long time.

This means that his cells have been tempered for a long time, and all the data indicators are far superior to ordinary cells.

But human exercise has a limit to the cell refining process.

Even if one starts training at a young age, one will never become a powerful martial art like in the novel.

Modern martial arts is nothing more than an exploration of the techniques of exerting force on the human body.

The strength of our human body muscles can be released reasonably, and it is easy to break a small tree that is as thick as the mouth of a bowl.

In addition to the upper limit of exercise tempering, human cells cannot become so powerful.

Another important reason is that the life span of cells is very short.

Normal people only need more than 6 years to replace all the cells except neuron cells.

It is the two important reasons, the upper limit of cell quenching and the lifespan of cells, that limit the self-reformation of human cells.

After a long period of accumulation in our cell laboratory, we have now discovered that under the action of a certain kind of biological energy, cells can be tempered repeatedly.

This kind of quenched cells has higher strength and longer lifespan, and newly differentiated cells can also quickly complete the quenching, allowing the strengthened cells to continue to maintain.

After listening to the narration of the two scientists, Zhao Tianyuan said pleasantly: As long as the human body is guaranteed to have no problems, both methods are good choices, and I can't judge which method is better now.

Chen Jin whispered in Zhou Yu's ear: Children make choices, of course we want them all.

When Zhou Yu heard this, his eyes lit up, and he made a decision: We don't know which method will succeed in the end, so we should go hand in hand, and don't give up on both solutions.

Perhaps a certain scheme was successful in the end, and perhaps the two schemes worked together to produce an effect of one plus one greater than two.

Wang Xiaoxiao bit the bullet and begged: Mr. Zhou, if you want to realize genetic modification, it is extremely dangerous, and human experiments are definitely not possible.

This is a modification aimed at human genes, and animal experiments cannot be carried out.

We must use clones, it is the best experimental body.

But the legal and public opinion stakes are high.

Tao Shengwen also supported: We carry out cell transformation, and the best experimental subjects are also human clones.

Human cloning is the best and irreplaceable experimental subject in the field of human biological research.

Zhou Yu was struggling. Seeing Chen Jin's gaze, he immediately decided: The company is in charge of human cloning. You should carry out the preliminary preparations for the experiment first, and the funds for the project will be allocated soon.
