I really don't want to be a doctor

Chapter 413 Incredible Mesenchymal Stem Cells

While Jing Xiaoran was thinking, Zhu Xianqing on the stage had already started to give a speech.

"A notable feature of modern anti-tumor drugs is the emergence of a group of drugs that target molecular abnormalities—that is, targeted drugs. The most representative drugs are tyrosine kinase inhibitors that target abnormal epidermal growth factor signaling pathways. Currently According to whether target detection is required, commonly used small molecule targeted drugs and macromolecular monoclonal antibody drugs can be divided into two categories..."

"So, today my topic is the development of new anticancer drugs."

Zhu Xianqing's main research direction at Pfizer is targeted drugs in the field of tumors. In addition to his current immune checkpoint inhibitor project, he can be regarded as an expert in the field of tumors.

"Targeted drugs?" Harris smiled slightly.

This came right at his gunpoint, as his field of research happens to be oncology.

Although Harris did not receive any good projects in the laboratory, the US National Laboratory is a national key experiment after all, and the things Harris comes into contact with every day are naturally at the international leading level. Class.

Zhu Xianqing's talk today did not involve immune checkpoint inhibitors, but the students sitting in the back row couldn't understand it at all.

"Senior Luo Xin, the teacher on the stage, what is he talking about? This targeted drug or something, I don't understand it at all!"

Sitting next to Luo Xin was a sophomore girl from Ning'an Medical College. Both she and Luo Xin were members of the student union, and they also took the opportunity of this academic exchange to come to Shenzhou Laboratory.

Luo Xin smiled and explained in a low voice: "This is a new type of anti-tumor drug, a tyrosine kinase inhibitor targeting tumor molecular pathways..."

"Senior sister, you are really amazing, you know such profound knowledge!"

"Hey, these are the most basic knowledge." Luo Xin said with a smile, "You have never been in contact with it, so you feel that it is unfathomable, but after you have really studied it, you will understand that it is actually very simple."

"That's a good thing to say, but it's very difficult to enter the Shenzhou laboratory. There are only a few people who can come to study every year." The junior girl smiled bitterly, "I will never have the opportunity to study in the laboratory again."

……

The content of Zhu Xianqing's speech is very simple, he is just a role of throwing bricks and attracting jade, so that the next people can play better.

But for the students in the background, no matter how you listen to it, it is a "book from heaven".

About 10 minutes later, Zhu Xianqing finished his speech, and there was warm applause in the hall.

Although most of the students couldn't understand, most of them were very supportive.

Harris, who was sitting under the stage, looked at Zhu Xianqing the whole time, with a completely nonchalant appearance.

"Peter, just now you always said how powerful the Shenzhou Laboratory is. Now it seems that even a molecular targeted drug is not clear, that's all!" Harris smiled.

He has a good understanding of the research on molecular target tumor drugs. Except for a small number of people present, his knowledge reserve exceeds most of the people.

Peter shrugged his shoulders and said, "This is the first scene, and there may be more in the future."

"Oh, then I'll just wait and see."

……

Zhu Xianqing's speech was over, and Jeffrey was the second to give a speech.

"Who is this?" Harris looked at Peter suspiciously, "Could it be that there are other laboratories participating in this academic exchange besides us?"

"No." Peter shook his head, "He is a member of Shenzhou Laboratory."

As soon as he finished speaking, Jeffrey's profile appeared on the projection screen.

"Jeffrey, Lawrence Berkeley National Laboratory?"

After seeing the introduction on the screen clearly, Harris couldn't help muttering.

The global ranking of Lawrence Berkeley Lab is even higher than them!
Peter continued: "He is one of my PhD classmates, but he came to the Shenzhou Laboratory before graduation."

"That means he hasn't got Lawrence's diploma yet?" Harris said.

"Yeah." Peter nodded.

He gave up his degree from the National Laboratory of the United States and came to a little-known laboratory in China instead.

Well, is this person's head flooded?

Harris carefully looked at Jeffrey on the stage, wanting to see what this crazy person looked like.

As soon as Jeffrey came to the stage, the students in the audience concentrated their attention.

"Is this foreigner also a researcher at the Shenzhou Laboratory?"

"I see that he was introduced from the National Laboratory of the United States."

"Is the Shenzhou Laboratory so powerful? Can it attract foreign research institutes?"

……

Jing Xiaoran sat on the rostrum, and he looked at Jeffrey with great interest.

This foreign friend gave him too many surprises.

When Jeffrey first came to the Shenzhou laboratory, Jing Xiaoran thought he was just here for sightseeing, so he came to the laboratory to have fun.

Unexpectedly, it took him more than half a year to do this, and he really made a lot of things, published a few high-scoring SCI papers, and taught Hong Sheng, an excellent student, by the way.

"Hi everyone, I'm a researcher from Shenzhou Laboratory." Jeffrey stood in front of the rostrum and said with a smile.

Although he has been in China for nearly a year and can communicate in some short spoken Chinese, it is better to use his native language when speaking of professional words.

In this way, the interest that the students in the audience had just raised was lost again.

Jeffrey's speech was very fast, and there were so many technical terms that the students in the audience couldn't understand him at all. Even some researchers in the Shenzhou Laboratory had difficulty understanding what he said.

However, Harris and others listened attentively to Jeffrey's speech.

"I believe everyone has heard of the biggest scandal in the academic circle a year ago." Jeffrey attracted the attention of Harris and others as soon as he opened his mouth, "Professor Piero Anversa's paper on cardiac stem cells contained data falsification , and my current project is based on cardiac stem cells."

Hearing this, Harris frowned slightly in the audience, "Myocardial stem cells? Hasn't it been proven that they don't exist at all? What else can this person do?"

Only Jeffrey on the stage continued: "Although myocardial stem cells do not exist, our Shenzhou laboratory has found another way to find another kind of cells that exist in the myocardium, that is, myocardial mesenchymal stem cells. Mesenchymal stem cells Can differentiate into a variety of cell types, including osteoblasts, adipocytes, skeletal muscle cells, islet cells, and cardiomyocytes, among others."

"The experiments we have done so far have confirmed that myocardial mesenchyme can be transplanted into the body and transformed into cardiomyocytes to repair infarcted myocardium. Animal studies have shown that mesenchymal stem cells can improve myocardial function..."

As soon as Jeffrey finished speaking, Harris' eyes widened in the audience.

Watching the dynamic pictures of PPT flashing on the projection screen, Harris felt a little unbelievable.
