I reach the pinnacle of life by learning

Xun'an Biopharmaceutical No. 02 Laboratory.

Both breaths were warm and heavy.

Ever since Qiao Yu took the initiative to kiss Song Tianyu a few days ago, every time Qiao Yu entered the laboratory these days, he would always be kissed against the wall.

Although it will not exceed 10 minutes each time, Qiao Yu feels that it will greatly affect the progress of the experiment because of the need to calm down and chirp later.

Sure enough, human beings can't escape the true fragrance theorem.

A few days ago, he was still wondering if he couldn't get up, but after a few days, he found that his body was very honest.

During the breathing gap, Qiao Yu wanted to take a step back, but was firmly pinched by a hand.

With the laboratory wall behind him, there seemed to be no retreat.

"Well... Qiaoqiao, kiss for a while."

Song Tianyu held his face and spoke vaguely.

Qiao Yu's legs softened after being kissed.

He wondered if Song Tianyu's talent was a bit crooked. It was obviously everyone's first time in a relationship, but after a few days of practice, the other party's kissing skills improved by leaps and bounds, making him look like a rookie with a bad level.

After a while, Qiao Yu remembered that Song Tianyu probably wasn't in love for the first time, he seemed to have an online girlfriend before.

But since it's an online dating girlfriend, I'm afraid there's no way to practice facing the air in the air?

Qiao Yu tried to regain the initiative. He had never eaten pork but had seen pigs run. He put his arms around Song Tianyu's waist with his backhand.

It's a pity that he overlooked one thing, that is, there is a little height difference between the two people in the film and television drama.

Now that Qiao Yu is 184, he can't be called short, but Song Tianyu is two centimeters taller than him. Although 2cm doesn't seem to be much, but on the height of a human being, it is also the distance between the lips facing the chin of others, which makes him look like It's throwing yourself in the arms.

There was a pleasant smile in Song Tianyu's eyes, and his words became sticky: "Qiao Qiao..."

After working hard for a long time, Qiao Yuren didn't feel good about kissing him, and he was still out of breath.

He calmly pushed the person away, his usually light lips were bright red and moist: "Enough, work."

Only then did Song Tianyu let go unwillingly.

Today is the last day of National Day, and Qiao Yu hasn't been to Sun Rui's biology laboratory for four days.

He sat in front of the workbench and dug out the mouse experiment that he designed yesterday.

How to prove that cardiac stem cells are fake is a question that Qiao Yu has been thinking about recently.

Internationally speaking, "cardiac stem cells" generally refer to "c-kit positive cardiac stem cells".According to the current cell tracking technology, after the stained c-kit+ enters the heart, it will multiply and differentiate in the cardiomyocytes, allowing the necrotic myocardium to function again.

But because it was confirmed to be false, Qiao Yu boldly guessed that in the animal experiment, it should be that the labeled c-kit+ had penetrated into the cardiomyocytes.It was as if the bag had been punctured, and the water inside was exposed and sprinkled on the surface of the heart muscle.It does not prove that c-kit+ repairs damaged cells.

In fact, at present, many scholars have questioned whether the theory of "cardiac stem cells" really exists.

Because of the extremely rigorous approach, the repeatability rate of this experiment is too low, let alone the next step of drug research.

Many laboratories are wasting time and energy for no reason, and naturally they are not happy.

Of course, the main thing is a waste of money.

But Anvisa said that there was a problem with the other party's experimental method.

In 2001, Anvisa was honored as a tenured professor at Harvard for proving the existence of "cardiac stem cells".In the following ten years, he won numerous honors because of this research achievement, and his 74-page resume is full of award-winning experience and honorary certificates.

Why, even though someone felt something was wrong, they still couldn't expose Anvisa's lies?

Because Anvisa is highly praised, it is no exaggeration to say that he is a god in this field.There are also countless people who have invested a lot of resources for this, and the sunk cost is so high that it is unbelievable.

Most importantly, with the current level of cell tracking technology, no conclusive evidence can be found.

Song Tianyu picked up the rat food and started feeding the mice.

The mice were bought from the laboratory next door. They are non-polluting and nuisance-free. They are pure natural and authentic laboratory mice with heart disease genes.

There is one breeding male and three breeding females.The mother mouse is already pregnant, and she is waiting to give birth to a baby mouse.

Raising mice by oneself is also a basic operation in a laboratory.

Qiao Yu thought for a moment, then put down the pen.

"Take out Poseidon." He said to Song Tianyu, "Poseidon has a heart attack. Let me take it out first to see how c-kit+ performs with traditional tracer technology."

Song Tianyu named all the four mice in the laboratory, and Poseidon was the only male mouse.

Song Tianyu said "oh".

After raising it for a few days, Song Tianyu also had some feelings for Poseidon. He put on his gloves, took out the fat Poseidon with big ears, fondled the mouse's head lovingly, and skillfully twisted the cervical spine to death.

It's a pity that the rat food I just swallowed hasn't had time to digest, it's a waste, if I knew it, I wouldn't have fed it just now.

Under the microscope, the stained c-kit+ cells appeared in the cardiomyocytes, which undoubtedly proved from the results that Piero Anvisa was right.

Qiao Yu pondered for a moment, then contacted Lin Qin who was far away overseas.

Lin Qin is currently working in the laboratory of Merkel Pharmaceutical Company and is employed as a middle-level researcher.

Merkel is an oligarchic pharmaceutical company in Germany, dedicated to innovative pharmaceuticals and cutting-edge life science technologies.

Many popular drugs on the market, such as Sigma, Erbitux, and Stanine, are all patented products of the Merkel Group.The blood cancer targeted drug that Qiao Yue took before was also a product of Merkel's research.

Previously, many of the bulk equipment that Qiao Yu purchased were entrusted to Lin Qin to purchase.

Qiao Yu: Senior, I want to ask a question.Is the inducible recombinase Cre/loxp system available for purchase?

This is the result Qiao Yu got after checking a lot of information.

Before, he asked Lin Feng if there was a technology or machine that could simultaneously trace the lineage of c-kit+ cells and cardiomyocytes in time, and the answer he got at first was negative.

Cell lineage tracing refers to the use of various methods to mark cells and track and observe the activities of all cells including their descendants.

However, the tracer cannot be applied to all cells, and some cells may even shrink and die as a result.

Finally, a professor in the field of biological genes asked Lin Feng to tell that Merkel recently developed something called the inducible recombinase Cre/loxp system, which greatly broadened the application range of cell lineage tracing technology, maybe You can try it.

Lin Qin smiled: You are well informed.But the system has not yet been officially put into production use, and has not even been approved for sale.It may be more than a year before it goes into circulation.

Qiao Yu: Can I buy it now?Can you buy it?

Lin Qin: Let me ask for you.

A few hours later, Lin Qin gave a reply.

Lin Qin: Sorry, it's still not for sale.

Because he knew that Qiao Yuhao was not short of money, Lin Qin specially added, "There is a price but no market."

Lin Qin: My authority is low, so I can't make the decision... Uh, but the company plans to promote this technology at the International Biotechnology Conference (IBS) in a month, and trials should be allowed at that time.If you can participate in IBS, you can try to persuade Merkel's chief scientist to give you a chance to try.

However, Lin Qin felt that the possibility of this should be very low.

First of all, IBS can be regarded as the top international biotechnology conference in the world.It is equivalent to the "International Congress of Mathematicians" in the mathematics world.Among the participants, probably more than one person has won the Nobel Prize. At present, Qiao Yu is not eligible to participate.

Of course, ordinary students may not have heard of this conference, and naturally they would not want to attend it.

Secondly, how could the Merkel Group allow an unknown young man to try out his latest technology.

The Merkel Group is the world's top biopharmaceutical company, and the experimenters they invited must be big names in the industry. This matter is beneficial to the reputation of both parties, and it is a win-win situation.Letting Qiao Yulai means that Merkel is unilaterally doing charity.

But capitalists don't do charity.

Qiao Yu put down the phone, feeling that the experiment seemed to have an answer, but it seemed that there was no answer.

To prove falsification, it is necessary to prove that c-kit+ has nothing to do with cardiomyocytes and will not produce a reaction.

To prove the above experiment, new technology is needed.

New technology cannot be bought unless he can participate in IBS and convince the chief scientist of the Merkel Group to give him a chance to experiment - he doesn't even know the name of the scientist.

Although it sounds difficult, Qiao Yu plans to try.

Qiao Yu found Professor Ye's contact information.

Qiao Yu: Mr. Ye, has the school received the invitation from IBS?

Ye Qinxue happened to be using his mobile phone, and he replied quickly: Received, there are three places in total.The school is going to let a group of young and middle-aged professors go to learn more, what's wrong?

Ye Qinxue did not say one more thing.

More than a dozen professors of the right age were torn apart for the sake of these few participants. Ye Qinxue, as one of the voters, was harassed every day.

Qiao Yu cheekily asked: Professor, if I want to participate in IBS, is there a way?

Ye Qinxue: ...? ?

Ye Qinxue had received a message from Sun Rui before, saying that Qiao Yu was a little ambitious, Ye Qinxue thought that it was normal for young people to be young and vigorous, but looking at it now, this is not going to the house, but directly thinking about going to heaven.

Ye Qinxue thought for a while: If he is a "scholar", it must be impossible.However, the professor who got the quota is generally allowed to bring a student to help the professor distribute the thesis booklet, do some chores, and learn a lot by the way.

The professors are usually their own disciples, which have nothing to do with Qiao Yu.

Qiao Yu: May I ask, which professors in the School of Biological Sciences got their places?

Ye Qinxue: Kou Yuhang, Sun Rui, Zhang Kaiwei.

Kou Yuhang is his teacher in molecular chemistry class.Sun Rui is the boss of the laboratory.Zhang Kaiwei has never been in contact with it, so he has no impression.

Qiao Yu wrote down this note thoughtfully, and said sincerely, "Thank you, Professor."
