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

The meeting was attended by Wang Xiaoxiao, a member of the Science and Technology Committee, director of the Institute of Genetic Sciences, and Tao Shengwen, director of the cell laboratory.

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

Zhou Yu first spoke: "If you find a problem, you must solve it, and we found that astronauts survive in space, and many sub-health problems will occur in half a year."

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

With our current technology, we can only choose whether to genetically modify the human body or to modify it cells.

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

Cell modification is to make human cells stronger by quenching cells, so as to enhance the adaptability of the human body. ”

Qi Zheng, a Chinese medicine expert, immediately objected unequivocally: "I strongly oppose the method of genetic modification, and we cannot let foreign genes slander our human gene pool."

Some evil scientists, modify the baby's genes.

She was only changed by a genetic locus, which can have terrible consequences.

This altered gene is likely to create a new genetic disease that will pollute our entire human gene pool.

Hereditary diseases such as hemophilia and albinism are genetic mutations at a certain gene locus, and it may be just one person's gene mutation at that time.

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

It's just a change in a genetic locus, and if you genetically modify the human body, you're going to change thousands of genetic loci, and you don't know what terrible consequences will happen.

It may even be that our decision has directly caused a major change in the gene pool of the human population, and we don't know what kind of terrible chain reaction it will have. ”

"One bottle is not satisfied, half a bottle is clattering. After reading a little popular science article, I thought I had the truth.

This kind of person is the kind of person who describes Dr. Xiang Qi. Wang Xiaoxiao politely waited until Qi Zheng finished speaking, and he immediately replied.

"It's like we're using a gene-editing approach to solve hemophilia that has plagued humans for years.

It is by modifying the patient's genes, correcting the defective parts of the patient's genes, and using the intact genes to form hematopoietic stem cells that are re-delivered to the patient's bone marrow.

This method is an effective cure for hemophilia, a genetic disease.

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

The answer I give is that there 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 proven to be correct and can solve the disease, we do not engineer germ cells, but choose to modify somatic cells.

We are careful to use gene-editing tools to prevent the entire human gene pool from being polluted by changing the balance of the human genome because of what we think is a well-intentioned method.

Genetic modification to strengthen the adaptability of the human body, it must be the somatic cells of normal people, and we will never touch the taboo of human reproductive cells.

We at the Institute of Genomics have been studying the ability of certain gene fragments to realize, and have discovered many protein structures with special functions.

I want to find certain 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: "This is my mistake, I don't know at all, there is 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 the functional protein expressed by special genes, it can completely change the state of the human body.

As long as we are sure that this protein will not cause side effects to humans, we can still accept this level of genetic modification.

Since birth, our human body has been injected with a lot of xenogeneous proteins, the most common being 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, I would like to 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 is that his cells have been tempered for a long time, and all the data indicators are far beyond ordinary cells.

However, human exercise has a limit to the cell quenching process.

Even if you start exercising from a young age, you will never practice a powerful martial art like that.

Modern martial arts are nothing more than an exploration of the human body's power techniques.

The strength of our human muscles, reasonable release, slapping a small tree with the thickness of a bowl, that is a breeze.

In addition to the upper limit of the human body's motor tempering, it cannot become so powerful.

There is another important reason, and that is that the lifespan of cells is very short.

It only takes more than 6 years for a normal person to replace all the cells except neuronal cells.

It is the two important reasons of the upper limit of cell quenching and the longevity of cells that limit the self-transformation of human cells.

After a long period of accumulation, our cell laboratory has now found that under the action of a certain biological energy, cells can be repeatedly tempered.

This kind of quenched cells have higher strength and longer lifespan, and the newly differentiated cells can also be quickly quenched, so that the strengthened cells can continue to be maintained. ”

After listening to the two scientists, Zhao Tianyuan said in surprise: "As long as there are no problems in the human body, these two methods are good choices, and I can't judge which method is better."

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

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

Maybe one of the options will be successful in the end, or maybe the two will work together to produce an effect where one plus one is greater than the sum of its parts. ”

Wang Xiaoxiao stubbornly pleaded: "Mr. Zhou, if you want to achieve genetic modification, it is extremely dangerous, and human experiments must not be carried out."

This is a modification of human genes and cannot be tested on animals.

We had to use a clone, and it was the best test subject.

But the legal and public opinion risks involved are significant. ”

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

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

Zhou Yu was struggling, he saw Chen Jin's eyes, and immediately decided: "The company is responsible for cloning, you first carry out the preliminary preparations for the experiment, and the project funds will be allocated soon."
