In a normal human body, after the embryo is fully developed, there will no longer be any totipotent stem cells in the body.

In theory, if there are always totipotent stem cells in the human body, cell replacement can always be achieved, and the human body will no longer age.

Of course, this is just the most ideal situation in theory. It would be very difficult to actually achieve such a perfect situation.

How to control these totipotent stem cells to differentiate in the appropriate direction is a difficult problem to solve.

After Xu You thought for a while, he said to Gao Mi:

"Professor Gao, arrange a new experimental topic. The goal is to cultivate a complete animal individual in the laboratory without the help of germ cells. There is also another experimental topic, through the directed differentiation of totipotent stem cells into what we have

necessary cells and develop into complete organs."

"Okay, I understand, Academician Xu."

These two experimental topics are of very important significance both in biology and medicine.

The first experimental subject looks similar to cloning, but in fact the principles are different.

To put it simply, cloning requires not only the somatic cells of the animal, but also the egg cells of the animal, and the embryo needs to grow up in the mother's body.

However, the method of using totipotent stem cells does not require any germ cells, and theoretically does not need to be developed in the mother's body.

The second experimental subject can be regarded as an upgraded version of therapeutic cloning.

Although therapeutic cloning will not develop into a complete individual, it will actually develop into a complete embryo during the treatment process.

And if totipotent stem cells can be induced to differentiate in a targeted manner, we can skip the embryonic development process and directly cultivate the organs we need.

This method is undoubtedly more efficient than therapeutic cloning and will completely avoid any ethical issues.

"With Professor Gao Mi's ability, it should only be a matter of time before they can solve these experimental problems."

Xu You still trusts Gao Mi and the entire project team, and he can safely leave them to deal with many problems that are not particularly difficult.

As for those more complicated problems, they can only be solved by Xu You himself.

At this time, Xu You thought of a more significant topic.

That is, how to achieve eternal life.

Simply realizing the reversal of totipotent stem cells only provides a possibility for immortality.

How to increase this possibility, there are still many problems that need to be solved.

Thinking of this, Xu You turned on his brain simulation skills and began to simulate specific environments in his brain.

Xu You has not only learned a lot about biology and medicine these days, but has also communicated closely with many experts, which has allowed Xu You's academic level in these fields to rise rapidly.

A solid academic foundation supports Xu You's accurate simulation of these processes.

Xu You first simulated a totipotent stem cell in his mind and tried to make this totipotent stem cell develop into a complete embryo.

"Without the protection of the mother, totipotent stem cells are still relatively easy to die. However, as long as the number of cells is sufficient and the environment of the cell culture room is as suitable as possible for cell differentiation, there is still no problem in developing into an embryo."

The survival rate of embryos using totipotent stem cells is not only lower than that of normal germ cells, it is also far lower than the embryo survival rate of cloning technology.

However, the multipotent stem cell technology does not require egg cells after all, which allows this technology to use a large number of cells at one time. Even if the success rate is low, it is not a problem.

As long as the stem cell reversal technology is mature enough, theoretically we can continuously obtain totipotent stem cells.

Next, Xu You continued to simulate the experiments of directed differentiation of totipotent stem cells.

As long as totipotent stem cells are directed and induced to become various multipotent and unipotent stem cells, they can then develop into various organs, tissues, etc. that we need.

This kind of technology can completely solve the problem of shortage of organ transplant donors.

As long as the patient can provide his own somatic cells, we can reverse these somatic cells into the stem cells we need and then cultivate the corresponding organs.

Because your own cells are used, there is no problem of recipient rejection. Once the organ matures, the organ can be transplanted.

Compared with those artificial organs, it will be more suitable for the patient's body, and there is no need to worry about possible radiation, interference and other problems from any electronic equipment.

However, these successful simulation processes have not yet made Xu You satisfied.

After all, even if an organ is developed from one's own cells, it still takes a long time to culture, and the transplant operation itself carries certain risks.

Xu You hopes that what can eventually be achieved is that the omnipotent stem cells in the human body can automatically repair cells according to the body's conditions.

In this way, you can keep your body young forever and not age due to age.

However, such a vision was not realized during the simulation process.

"No... Even if totipotent stem cells are injected into the body, these totipotent stem cells cannot automatically control the direction of differentiation, but differentiate almost randomly. This will not only not be conducive to the repair of body cells, but may also cause physical disorders.

."

This feeling is like having a group of elite soldiers but not a wise general, resulting in a leaderless group and the whole situation is like a piece of loose sand.

Because totipotent stem cells should not exist and develop fully in the body of animals, it is almost impossible for them to repair body cells independently.

"What if... there could be something that could give orders to totipotent stem cells?"

At this time, Xu You thought of another possibility.

If some way can be used to globally control all totipotent stem cells so that they can automatically detect the body and automatically update the cells that need updating according to the body's condition, then the problem will be solved.

And such technology is not completely impossible to implement.

"Nano robots...this technology should also be put on the agenda."

The so-called nanorobot refers to a very small robot that can perform various microscopic operations at the nanometer scale.

In some novels and movies, as long as the patient takes "nano-robots", the robots can automatically carry out various medical operations in the human body.
