After looking at it for a while, Yang Yunfan looked away and walked to the side, beside the Zhong family's disciple, carefully looking at the strange Moro Secret Hidden Flower.

The others saw Yang Yunfan walk away, and the curious people also went to the high-powered microscope and took a look. However, they are not medical experts, and they just think it is amazing at a glance, after all, the cells of the human body are difficult to see with the naked eye.

Although cultivators have good eyesight, they can't be used as magnifying glasses, and many times, they use their spiritual sense to feel the changes in the aura around them. There are some subtle differences between this sensory thing and what the eyes see directly.

After watching it for a while, everyone was relatively speechless, because they didn't understand it at all.

If you tell them about the five elements of toxins, mutual reincarnation and restraint, yin and yang and something, they will definitely understand. But I really don't understand the cells or something.

After muttering to each other for a while, Zhong Xueying walked up to Yang Yunfan and asked, "Little Brother Yang, what's going on? Tell us all! Don't think about it alone, one person counts the shortness and the other counts the long, more than a dozen of us here, all of whom have lived to be almost a hundred years old, and they are all more than a thousand years old, and we can always help you come up with an idea." ”

Yang Yunfan nodded and said, "What the predecessor said makes sense. We still have about three days to go, so there's no rush. Before that, let me tell you about the reason for the changes in this brother of the Zhong family. This is the reason for the cell mutation in his body. ”

"Okay, you have made the reason clear and found out the reason, so that we can prescribe the right medicine. Everyone else nodded their heads and felt like they were finally being useful. Thinking that with his knowledge over the past hundred and eighty years, as well as his awareness of the treasures of heaven and earth, he will definitely be able to come up with some good solutions.

It's just that as soon as Yang Yunfan opened his mouth, they were directly stunned!

"Generally speaking, cell differentiation in our human body refers to the process in which cells from the same origin gradually produce cell groups with different morphological structures and functional characteristics, and the result is that cells are different in space, and the same cell is different from its previous state in time. ”

Yang Yunfan thought about it, and first started from the most basic and intuitive place to popularize science for everyone.

"For example, when a stem cell divides, the gene expression of its daughter cells is regulated, such as DNA methylation, which becomes a different cell type. For example, when an all-potent zygote divides to a certain extent, its daughter cells will begin to differentiate in a specific direction, forming the muscles, bones, hair and other organs of the fetus. ”

As he spoke, he went to observe the faces of the others, and saw that they nodded slightly, as if they understood something. It's just that there is still some confusion in the eyes.

It doesn't matter, they've listened to it, and it's okay to have a basic concept. Originally, he didn't think that these seniors here could put forward any constructive suggestions for him. When he spoke to them, his main purpose was only to clarify his own thinking.

"Actually, the most basic DNA of these cells is the same. It's just that under the action of different environments, time and space, it will develop into different things. This situation is similar to an ancient saying, orange is born in Huainan is orange, and born in Huaibei is orange. Because the environment is different, the final result is naturally different. ”

"The essence of cell differentiation in our human body is actually the selective expression of the genome in time and space, and finally the production of iconic proteins through the opening or closing of different gene expressions. ”

"In general, the process of cell differentiation is irreversible. Therefore, when people grow up, they grow up, and when they get old, they get old, and you grow thighs, which is already an established fact. It's impossible to make you retract again. ”

Speaking of this, Yang Yunfan suddenly changed his words and said: "However, under certain conditions, differentiated cells are also unstable, and their gene expression patterns can also undergo reversible changes and return to their undifferentiated state, a process called dedifferentiation. ”

"Hmm, what does this mean?" Everyone followed Yang Yunfan's train of thought at first, but when they said this, they suddenly found that Yang Yunfan had overturned their previous theory, so everyone felt very uncomfortable, and suddenly their thinking was disordered, and they stared at Yang Yunfan.

Yang Yunfan knocked on the table and said, "For all cells, differentiation must be based on division, that is, differentiation must be accompanied by division. But...... The reverse is not true. Because the cells that divide don't necessarily differentiate!"

"What?"

Hearing this, everyone else was stunned and realized the meaning of this sentence.

At this moment, everyone felt that they seemed to have understood something, but there was a little fog in their hearts, and they couldn't see clearly. It's like the feeling of listening to the master's lecture on the scriptures when I was a teenager, the scriptures are very obscure, and they are surrounded by clouds and mountains, but I can see a little clue here, which makes people have a sense of joy of stealing the avenue.

"Little Brother Yang, please continue!" They all can't wait to hear Yang Yunfan talk about, although this is a medical theory, the essence of cultivating truth is to "remove the false and keep the truth", the more they understand their body, the closer their cultivation will be to the "truth", and their cultivation will naturally improve.

Yang Yunfan's unique speech seems to have opened a new door for them.

Now they realize that this may be a great opportunity.

Yang Yunfan didn't know why everyone's interest suddenly became so high, he didn't think much about it, and continued: "In fact, after research, you will know that when the cell is more differentiated, its division ability will be worse. ”

"It's like, I draw a rune with aura, if I only draw a line, of course it can be changed in the future, no one knows. But I've already drawn hundreds of lines according to a fixed trajectory, and I'm afraid that experienced people can tell at a glance what runes I'm drawing. ”

The metaphor was very vivid, and everyone nodded secretly. I felt that the fog in front of me had disappeared a little, and I became more and more interested in the truth in the fog.

Yang Yunfan continued: "After the cell differentiation, the tissue is strange and has a high degree of stability. But I just studied it, and the toxin of this Moro Secret Flower has some specificity and can dedifferentiate differentiated cells. And so that the carrier, become suitable for the growth of Moro Hidden Flower seeds. ”

Speaking of this, Yang Yunfan suddenly walked over, pointed to the limbs of the Zhong family disciple and said, "Look at this Zhong family brother, his limbs have been shortened, and his hands and feet have become the size of a baby. In fact, it's a kind of de-differentiation!"

"Little Brother Yang, what I just said turned out to be all hit!"

When everyone saw it, they were all amazed. They didn't look closely before, and thought it was atrophy caused by poisoning. At this time, I found that the originally rough hands and feet of the Zhong family disciple had become as fat as a baby at this time, but they were white and tender, full of collagen.

"This kind of medical theory is almost like the Tao!" After a while, everyone looked at Yang Yunfan, no longer as if they were looking at the juniors of the cultivation realm, but showed a look of reverence.
