Zuo Shifeng looked at Zhu Lao eagerly, because Zuo Wei's sexual happiness may be pinned on the other party's mouth.

Zhu Lao said slowly, "First of all, we have always had a misunderstanding in the self-healing function of human cells, that is, the self-healing ability is mistaken for the ability to rebuild, which are two different concepts. ”

All the doctors present listened attentively, and it was very rare to be able to hear Zhu Lao's lecture.

"In the pathological state, after cell and tissue necrosis or defects, if the degree of damage is mild and the injured cells have strong regeneration ability, the same cells around the injury can proliferate and differentiate, and completely restore the original structure and function, which is called pathological regeneration. For example, second-degree scalds of the epidermis often cause blisters, and cells above the basal cells are necrotic, at which time the basal cells proliferate and differentiate, and the original structure and function of the epidermis are completely restored. In the case of pathology, the tissue that cannot be regenerated and repaired can be repaired by granulation tissue and scar, that is to say, the repair and regeneration function of our human body is based on the replacement of damaged cells, of course, there are many limitations to regeneration, and I have to mention another kind of cell, stem cells! ”

Hearing this, everyone even breathed slowly, the most mysterious thing in the medical world is two things, one is the birth process of life from nothing, which involves theology and physics, which has long been the most controversial topic.

The other thing is the body's self-healing ability, that is, the mysterious cell repair, it can be said that whoever masters the secret of the repair of human cells will have a chance to obtain eternal life!

Zhu Lao paused and pointed to his arm, "There are all kinds of cells in our body, brain cells, lymphocytes, bone cells, muscle and skin cells, connective tissue and interstitial cells, these cells are collectively called somatic cells, they are all adult cells, and the corresponding stem cells are stem cells, which are multipotent cells with self-repair ability, and can be divided into embryonic stem cells and adult stem cells according to the stage of development of stem cells.

For example, it is easy to understand, adult cells are like an adult, this cell type is the work they are engaged in, some cells are doctors, some cells are teachers, some cells are workers, they have a clear division of labor, stick to their posts, play their own role, each cell is an indispensable part of the human body, only they work together, ready to substitute at any time, our human body can function normally.

Next, let's talk about embryonic stem cells, since they correspond to them, I don't think I need to say what they correspond to, right? ”

Liu Tianqi said with a smile, "Zhu Lao, don't sell Guanzi, embryonic stem cells correspond to children who do not have adults, they are stored in the bone marrow and used to replace injured tissue cells, which can be converted into adult cells to repair injured tissues." ”

Zhu Lao smiled, "Xiao Liu, why did you become so quick now, this is not good." ”

In front of so many people, it is estimated that only Zhu Lao dares to call Liu Tianqi, the 301 leader, and the party secretary of the hospital is Xiao Liu.

Liu Tianqi was not angry, he admired Zhu Lao from the bottom of his heart, a person who dedicated his life to medical research. Just a wry smile, secretly saying that you have no problem selling Guanzi, but I am afraid that Zuo Shifeng does not have the patience to listen to your tirade.

Sure enough, Zuo Shifeng was in a hurry, and motioned to Zhu Lao to continue, "Zhu Lao, you say." ”

Zhu Lao nodded, "In addition, stem cells are also divided into many types, which are used to correspond to the adult cells in our body, such as shaft cells, which are specially used to repair bone damage, and they are not only one, which I have already said."

Because stem cells can only repair and replace injured tissues, and our human body functions are very complex, for the damage of some functions, can only play a certain role, for the damage of basal cells, unable to completely repair, otherwise we humans can live forever, the basal cells of the cavernous body are seriously damaged, and the general dry fine repair power is very limited, unless ......"

Speaking of this, Zhu Lao hesitated for a moment, maybe he thought of something, wanted to say it, and gave up again.

Zuo Shifeng didn't understand what Zhu Lao said at all, but he still heard a little something, that is, the reason why Zuo Wei formed irreversible damage was entirely because stem cells had limited repair ability to basal cells, resulting in damaged cells not being perfectly replaced.

And if the rumor that his friends abroad told him is true, then there is hope.

Thinking of this, he immediately asked, "Zhu Lao!" I heard about something a while ago, and I don't know if it's true. ”

Zhu Lao became serious, as the research institute of the National Bioengineering Laboratory, there was something in the world that could escape his ears, and with the medical records brought by Zuo Shifeng, he had vaguely guessed the rumor.

"Oh? A rumor, let's talk about it. ”

Zuo Shifeng looked at Zhu Lao, "I heard that someone abroad has successfully cultivated a drug called totipotent stem cells, which can achieve a perfect cure for any injury. ”

Suddenly, the silence in the conference room seemed to freeze in an instant, and everyone even lost their breath, leaving only all kinds of different eyes looking at Zuo Shifeng.

There was silence for less than three seconds, and with a bang, the conference room seemed to be hit by hundreds of shells, and there was a deafening buzz, and everyone began to talk about it.

"Dr. Chen, I've heard that rumor too, but I don't know if it's true or not."

"I've also heard about it, but it is estimated that it is impossible, the reason why totipotent stem cells are called totipotent is because they can be unconditionally converted into any kind of somatic cells, the conversion rate is extremely high, almost more than 99%, and any wound can be repaired, and this kind of cell is very small in our body, someone successfully extracted a few in the past few years, all of them were nominated for the Nobel Prize in Medicine, not to mention the successful cultivation, if this is cultivated, human beings will not be able to live forever!"

Another middle-aged doctor nodded hurriedly, "Yes!" I also think it's unlikely, the medical world is full of gossip, and last time I heard that a doctor in a private clinic abroad was going to perform the first head replacement operation in human history, and finally there was no news. ”

This is a bit yin and yang, a bit of a mocking tone, and I don't know if it's judged out of real difficulty, or because peers don't like each other.

Zhu Lao, who had not spoken, looked at the teacup in front of him, and his fingers tapped on the table rhythmically, not knowing what he was thinking.

"Ahem!" Liu Tianqi coughed violently twice, signaled them to pay attention, and then looked at Zhu Lao, "Zhu Lao, what do you think ......of this matter?"

Zhu Lao sighed with a little melancholy in his eyes, "Hey...... As a scientist in the natural sciences, I naturally hope that this is true, but no one can say that cells are the most basic biological tissues that make up our human body, with an average volume of 10 microns, containing hundreds of proteins and amino acids, and it is not easy to cultivate specific cells. ”
