Next.

Three o'clock in the afternoon.

The entrance of the experimental area of the Institute of Life Sciences.

Zhao Heng carried a white biological sample transport box in his right hand, which contained a sample of the spinal pith, and in his left hand, he carried a laptop bag, which contained Sun Xinxin's examination materials.

However, as soon as Zhao Heng arrived at the gate of the experimental area, he was stopped by the security brother, this is a national-level biological experiment center, of course, not everyone can enter.

"Hello, I'm Zhao Heng, and Professor Li Hongwei asked me to come."

Zhao Heng said very politely and cool security guy.

"Professor Li Hongwei?"

When the security brother saw such a young Zhao Heng, he was a little puzzled, because Professor Li Hongwei was the absolute elder in this experimental area, and he usually only brought doctors, so Zhao Heng, who seemed to be only in his early twenties, naturally aroused the suspicion of the security brother.

"Yes, just make a phone call to Lab 1 to make sure, it's troublesome."

Zhao Heng nodded and said.

This is a heavily guarded national laboratory, and if you break in, you may have to eat and stay free in the future.

"Okay."

Seeing that Zhao Heng was very polite, and he was very confident when he spoke again, the security brother nodded, turned around and went to call.

After a while, the security brother came out, but although he confirmed Zhao Heng's identity, he still felt a little unbelievable that Zhao Heng could have a relationship with Professor Li Hongwei.

Therefore, he kept looking at Zhao Heng, wanting to see where Zhao Heng was sacred, so that Professor Li Hongwei, who had always been strict, could give him this green light.

"Can I go in?"

Zhao Heng saw that the security brother couldn't stop looking at himself, so he asked.

"Well, yes, this is a temporary pass, but you can only go to Lab One, and you must carry this pass with you at all times."

The security guy nodded and handed Zhao Heng a silver-white chip card.

This chip naturally has the function of monitoring, which is also a measure of secrecy.

"Okay."

Zhao Heng took the chip card and put it in his pocket.

Next, the security guy opened the door, and Zhao Heng finally came in.

This place is really hard to enter!

Zhao Heng couldn't help but feel a little emotional.

It deserves to be a national biological experiment area.

After a while, Zhao Heng found the No. 1 laboratory, and after swiping the access control with the chip card, Zhao Heng entered the laboratory.

When he came in, Zhao Heng saw several scientific researchers in white coats, and these people should be members of Professor Li Hongwei's scientific research team.

And Professor Li Hongwei is directing a scientific researcher to operate something, and there is a person standing next to him, who is Assistant Professor Wei Jinghao.

Seeing Zhao Heng coming in, Li Hongwei beckoned to Zhao Heng.

Seeing this, Zhao Heng hurriedly walked towards Li Hongwei and quickly walked to his side.

"Xiao Zhao, did you bring the sample?"

Li Hongwei looked at Zhao Heng and said straight to the point.

To be honest, he was also quite interested in the degenerative changes in the spinal cord that appeared in top athletes, otherwise, he would not have taken time out of his busy schedule to let Zhao Heng come over.

"Well, Professor, the sample is here."

Zhao Heng put the white biological transport box on the workbench and said slowly.

"Xiao Wei, you can do a microscopic projection."

Li Hongwei nodded and said to Assistant Teacher Wei Jinghao.

"Okay, Professor."

Wei Jinghao nodded, glanced at Zhao Heng, opened the white biological transport box, took out the bone marrow smear inside, and put it under the microscope.

Then Wei Jinghao operated on the workbench, and the image of the bone marrow smear under the microscope was transmitted to the big screen.

Li Hongwei looked at the screen very casually at first, but the more he looked at it, the more solemn his face became, and then, he personally operated the microscope and carried out several examinations.

"Well, it's true that it's a bone marrow degeneration, but it's pretty rare for it to happen to someone so young."

After the test was completed, Li Hongwei nodded to Zhao Heng and said.

"Professor, with the condition of this patient's spinal cord, is it still possible to differentiate into neural stem cells?"

Zhao Heng saw that Li Hongwei had already determined the situation, and couldn't help asking.

"I've done it before to get pluripotent stem cells and various functional cells through cell fate regulation, but that's been done in mice. As for the clinical trials, this is the first time. ”

Li Hongwei thought for a while and said.

As soon as Li Hongwei's words came out, Zhao Heng noticed that he was talking about me, not us, or the team.

In other words, this technology, so far, has been mastered by Li Hongwei alone.

"Professor, can you give it a try? The patient is Sun Xinxin, a Winter Olympics skiing champion. ”

Zhao Heng saw that Li Hongwei was a little hesitant, so he told the identity of the patient.

He can't say this at the beginning, and if he says it at the beginning, it will become persecution.

Now is just the right thing to say.

"Sun Xinxin? You're talking about the ski champion who got injured while competing abroad? ”

As soon as Zhao Heng's words came out, Li Hongwei said with some surprise.

Sun Xinxin has naturally heard of it, and he is a champion hero who won glory for the country at the Winter Olympics.

"Well, yes, just transferred back from the Mayo Clinic."

Zhao Heng nodded and said.

"In that case, let's give it a try. However, at present, only I can master this technique, and the time to cultivate differentiation is a bit long, at least a month. ”

Li Hongwei thought about it and quickly agreed.

He still admires the champion heroes who have won glory for the country, and this must also be saved.

"Professor, can this time be shortened?"

Hearing Li Hongwei say this, Zhao Heng was happy at first, but when he heard this one-month deadline, his heart suddenly sank.

In Sun Xinxin's case, the brainstem aneurysm in the brain could not last for a month at all.

"Unless I have someone working with someone who is about the same level as me in cell fate regulation, I can't shorten that time."

Li Hongwei said helplessly.

Cell fate regulation, which can be said to be the most cutting-edge and high-end technology in the world, is so easy to master.

"Professor, I have a presumptuous request, can I observe the time of your operation?"

Hearing Li Hongwei say this, Zhao Heng decided to take a risk.

"Observe? Yes, yes, you can. ”

When Li Hongwei heard Zhao Heng's request, he suddenly felt a little strange, but he still agreed.

If he wants to talk about the technology of cell fate regulation, he would like a few more people to master it, let's just say that these doctoral students under him, he teaches this technology without hiding it at all, but none of them can master it.

This is a technology that relies on personal ability to realize, rather than producing biosynthetic drugs, and of course it is not afraid of people to see it.

If you can learn it by looking at it, Li Hongwei is still happy.

"Then please professor, in terms of fees, I will try to coordinate."

Zhao Heng said gratefully.

"It's only a few dollars, and if this thing is done, it will be of great significance. And, without you, I wouldn't have had this opportunity to conduct clinical trials. ”

Hearing Zhao Heng talk about the cost, Li Hongwei waved his hand and said indifferently.

This cultivation and differentiation of a person's neural stem cells, even if it is used in the laboratory, the cost price is more than 100,000 yuan at most, which is not a matter at all for Li Hongwei, who has hundreds of millions of scientific research funds every year.

In addition, the redifferentiation and cultivation of neural stem cells in the vestigial spinal pulp is a very significant experiment.
