Doctor: I picked up attributes in the hospital

Chapter 199 Cell Fate Regulation?The most advanced skill to date!
Two days later.

nine in the morning.

School of Life Sciences, Yenching University.

In the first laboratory.

Wearing a white dust-proof and sterile suit, Zhao Heng is watching Professor Li Hongwei redifferentiate the spinal cord into neural stem cells through fate regulation.

At the Dongfang Hospital, Gao Jun was shocked when he heard that Zhao Heng contacted Professor Li Hongwei from the School of Life Sciences of Yanjing University to cultivate stem cells.

Gao Jun readily agreed to Zhao Heng's request to come and observe. After Liu Ziang knew about it, he even asked Zhao Heng to go there with peace of mind. He would come in person to manage Sun Xinxin's bed.

With the support of these good teachers and helpful friends, Zhao Heng naturally came to observe Professor Li Hongwei's operation without any burden.

To be honest, although such an opportunity is rare, it is basically useless to other people, because it is too high-end, and you can't understand it, and you can't learn it.

While Li Hongwei was operating with his heart, Zhao Heng suddenly saw a white light ball that Zhao Heng was very familiar with but hadn't seen for a long time falling from Li Hongwei's body.

Zhao Heng was very excited at the moment. After so much preparation, it finally came.

Zhao Heng was familiar with the road, and Zhao Heng's heart moved. The white light cluster that only Zhao Heng could see turned into a stream of light and entered Zhao Heng's mind.

【Ding!Congratulations to the host, picking up Fusion Cell Fate Regulation (Proficient)! 】

The notification sound of the system also sounded at this moment. Zhao Heng had never felt that the notification sound was so sweet.

With the integration of "Cell Fate Regulation (Proficient)", Zhao Heng has a very in-depth understanding of this very high-end and difficult technology at once, comparable to a genius biological scientist who has studied several level of ten years.

However, Zhao Heng noticed that the fusion skills dropped and picked up from Professor Li Hongwei are only at the proficient level, which shows that there is still a lot of room for improvement in such skills.

Here, Li Hongwei has already finished an operation. During the short break, he saw Zhao Heng so focused, so he asked him: "Xiao Zhao, do you know that stem cells mainly experience two kinds of fate choices during the development process?" Is it?"

Li Hongwei's question is actually equivalent to teaching.

Therefore, he didn't expect Zhao Heng to answer at all.

"It should be the proliferation process of self-renewal, and the differentiation process of transforming into functional daughter cells."

Zhao Heng retrieved the fusion experience he had just fallen from Li Hongwei in his mind, and said slowly.

"..."

When Zhao Heng answered, Li Hongwei was stunned for a moment.

"Professor, am I wrong?"

Zhao Heng searched the experience in his mind again, and after confirming that it was correct, he asked with some doubts.

"Well, that's right, that's right. Um... Then let me ask you again, what are the key points to pay attention to in stem cell differentiation?"

Zhao Heng's answer was completely beyond Li Hongwei's expectations, so he decided to ask a more in-depth question. He wanted to find out where Zhao Heng was going.

"The differentiation of stem cells must not only ensure that stem cells provide the body with a steady stream of functional progeny differentiated cells; but also ensure that there are sufficient reserves of stem cells in its microenvironment. At the same time, it is necessary to prevent stem cells from over-differentiation. The depletion of the reserve pool; and the avoidance of tumor-like structures caused by the excessive proliferation of stem cells."

"Professor, am I right?"

Zhao Heng quickly retrieved the information in his mind and continued.

"...You are right. Then let me ask you again, in stem cells, how does the Csn4 factor maintain the self-renewal of stem cells as a member of the COP9 complex?"

"Also, in the differentiated progeny cells, how does the abundantly expressed pro-differentiation factor Bam recruit Csn4 through competition, thereby converting other Csn protein components to play a role in promoting differentiation?"

Seeing that Zhao Heng answered again, Li Hongwei lost his composure a little, and quickly asked two questions that he had just explored recently.

He didn't believe it. If Zhao Heng could answer these two questions, it would be hell!
"Um.."

Zhao Heng pondered for a while. These two questions are very difficult. Even if he retrieves the knowledge and experience in his mind, it will take time, and he also needs to organize his language and expression.

"It's okay, Xiao Zhao, you can't answer, it's normal."

Seeing Zhao Heng stopped, with a face of hard thinking, Li Hongwei breathed a sigh of relief, and comforted Zhao Heng instead.

To be honest, Zhao Heng was able to answer the two previous questions. From Li Hongwei's point of view, this has the potential to be his student and inherit the mantle.

You know, he doesn't accept students easily.

"Professor, I figured it out."

Just when Li Hongwei secretly breathed a sigh of relief, Zhao Heng said that he had organized his words.

"Huh? You figured it out? It's impossible, tell me!"

Hearing what Zhao Heng said, Li Hongwei was a little incredulous, and asked repeatedly.

"CSN4, one of the self-renewal factors targeted by Bam, is an evolutionarily conserved multifunctional complex containing 8 protein subunits whose functions are..."

Next, Zhao Heng spent nearly 10 minutes explaining in detail the two most difficult questions raised by Li Hongwei.

When Li Hongwei listened to it at first, he was a little disapproving, but the more he listened, the more solemn his expression became. Zhao Heng's level of cell fate regulation technology was completely beyond his expectations.

After listening to Zhao Heng's narration, Li Hongwei suppressed the excitement in his heart, and asked a question that he hadn't solved yet in some inconceivable way.

"As CSN4 is also the only subunit not involved in stem cell differentiation among the 8 subunits, why do you think CSN4 has the opposite effect to other CSN proteins?"

After asking this question, Li Hongwei stared at Zhao Heng closely. He was really nervous at the moment.

"CSN4?"

When Zhao Heng heard Li Hongwei's question, he fell into search.

After a while, he shook his head at Li Hongwei and said, "Sorry, professor, I can't answer this question."

"Can't answer? Good! No, not good. Xiao Zhao, you really gave me a big surprise!"

Li Hongwei said a little indiscriminately.

When Zhao Heng said he couldn't answer this question, he immediately felt relieved. If Zhao Heng could even answer this question, then Zhao Heng was his teacher, not him here.

"Xiao Zhao, next, you come to work with me. I believe that with your help, the time of one month can be shortened a lot."

Li Hongwei looked at Zhao Heng carefully again. Although he felt that Zhao Heng's level was unbelievable in his heart, he felt frightened at first, but after the fright, he was full of surprises.

Zhao Heng is so young and has such a level, so why not worry about scientific research!
"Well, trouble, Professor."

Zhao Heng nodded humbly without any arrogance.

Zhao Heng participated in the cultivation of stem cells in this way of showing off, and Zhao Heng also wanted to shorten the cultivation time, which is also impossible.

What's more, Li Hongwei's actions are worthy of his admiration.

"All right."

Seeing Zhao Heng's humble face, Li Hongwei was even more satisfied.
