Doctor: I picked up attributes in the hospital

Chapter 273 Professor Li Hongwei's Amazing Research Achievement - Totipotent EPS Cells!

The next day.

nine in the morning.

Zhao Heng came to the Institute of Professor Li Hongwei, School of Life Sciences, Yenching University again.

Standing in the laboratory, Zhao Heng looked at the electronic screen in front of him. The picture displayed on it was the latest research achievement of Professor Li Hongwei's team. Using small chemical molecules to establish stem cells (EPS cells) with pluripotent characteristics in vitro for the first time , this kind of cells has stronger developmental potential and will provide a better source for preparing various functionally mature cell types in vitro.

"Professor, is this the latest EPS cell with pluripotency? This is amazing."

Looking at the electronic screen, Zhao Heng couldn't help but admire and said, thinking that this is the result of independent research and development by domestic scientists, Zhao Heng felt full of pride in his heart.

I don't know when he will be able to develop such scientific results independently.

At this moment, Zhao Heng couldn't help but think in his heart.

"Yes, after 20 years, EPS cells have finally been developed."

Professor Li Hongwei also said with admiration.

He is now 50 years old. Since he was 30 years old, he has been developing this achievement with his mentor at that time. Until now, after two generations of hard work, this achievement has finally come out. Scientific research is not easy. .

"The current ones are only the first-generation cells, Xiao Zhao. Now this project needs talents like you to join in. We will work harder to develop the second-generation or even third-generation cells, so that they can be put into clinical use soon. In the future, we will This totipotent EPS cell will be used to differentiate into functional blood cells, islet cells, and liver cells, and combined with gene editing technology to prepare a new type of anti-tumor CAR-T cells."

After a pause, Professor Li Hongwei said with pride.

Hearing his words full of pride, Zhao Heng was also inspired, and his heart was very moved.

"Professor, it is my honor to participate in such a project, and I will do my best."

Zhao Heng said seriously.

He is telling the truth, for such a great project, he can participate in it, which is already a very honorable qualification in itself.

Moreover, so far, Zhao Heng has only picked up the skill "Cell Fate Regulation" from Professor Li Hongwei. For a professor like Li Hongwei, he obviously has more than one skill.

Only in this way, Zhao Heng's schedule became even more tense.

"Very good, Xiao Zhao, I am very optimistic about you. Maybe you will take over this field in the future."

Professor Li Hongwei spoke very highly of Zhao Heng, and almost regarded Zhao Heng as his future successor.

It can be said that Professor Li Hongwei has never given such a high evaluation to any young scientist before. Think about it and you will know that Yenching University is the top university in China, and there are countless geniuses in it, but no one has won the mantle of Professor Li Hongwei. From the evaluation, we know how high the requirements and standards of Professor Li Hongwei are.

"Thank you professor, I will try my best."

For Professor Li Hongwei to value him so much, Zhao Heng felt very proud on the one hand, and on the other hand, it was also a kind of pressure.

Regarding this point, just look at the eyes of other doctoral students in the laboratory who followed Professor Li Hongwei when they looked at Zhao Heng.

Doctors who can follow Professor Li Hongwei can be said to be the elite of the elite, but no one can get such a high evaluation from Professor Li Hongwei.

It can be said that with the birth of EPS cells, Professor Li Hongwei's evaluation of academicians is already done.

In the future, in the field of domestic life sciences, Professor Li Hongwei will also be an absolute leader. Whoever can get the attention of Professor Li Hongwei at this time will simply reach the sky in one step.

It's no wonder that the other doctoral students looked at Zhao Heng with envy and hatred.

"Professor, now that the first generation of EPS cells has come out, the next research direction is to chimerize EPS cells into early embryos, and then participate in the development of various cell lineages of embryos?"

After a pause, Zhao Heng thought about it and expressed his thoughts.

"Yes, Xiao Zhao is right. But at present, the developmental potential of the first generation of EPS cells is limited to the tissues within the embryo, and it is difficult to develop into extraembryonic tissues such as placenta and yolk sac. Our future research focus will be on How to establish and maintain a stem cell line with potential for intraembryonic and extraembryonic development in vitro is also the most challenging problem in the field of stem cell research in the world."

Professor Li Hongwei appreciated Zhao Heng's idea very much, and said slowly.

"So there is still a long way to go."

Zhao Heng nodded and said.

Scientific research is endless, especially in the current scientific community, it is very difficult to research a brand new result.

"Yes, for now, although we have completed the injection of human EPS cells into early mouse embryos, and can stably chimerize into mouse embryonic tissues, the efficiency of the integration ratio in embryos is already sufficient compared to before. It has been improved by nearly 20 times, but there is still a long way to go before it can be applied to the human body or even clinically."

Professor Li Hongwei said slowly.

Next, Zhao Heng continued to participate in the development of the first generation of EPS cells as the assistant of Professor Li Hongwei.

By 11:30, this time the work was over.

It was only a morning to come to Professor Li Hongwei's side. In the afternoon, Zhao Heng had to rush back to work in the hospital.

Before leaving, Professor Li Hongwei said to Zhao Heng: "Xiao Zhao, you are really tired from running around here. Otherwise, I will tell your dean to let you stay here forever."

For Zhao Heng, Li Hongwei really appreciates it. On the one hand, Zhao Heng's level is simply beyond the scope of his age. On the other hand, Zhao Heng's attitude is also very correct. It can be said that in At work, Zhao Heng is an extremely serious and responsible person, which makes Professor Li Hongwei very reluctant to be such a good assistant to Zhao Heng.

"Professor, I still can't let go of the job at the hospital."

Zhao Heng could only politely decline Professor Li Hongwei's appreciation and invitation.

It is impossible for him to give up his work in the hospital, to save patients and cure diseases, which is his original intention of studying medicine.

"It's good that you young people have your own ideas."

Seeing that Zhao Heng said so, Professor Li Hongwei no longer insisted, but he still looked a little regretful. If Zhao Heng had been around all the time, then his research efficiency would have at least doubled.

"Professor, I want to ask something."

This is about to go, Zhao Heng asked Professor Li Hongwei.

It was also the result of Professor Li Hongwei's research this time, which greatly shocked Zhao Heng. He just remembered that this time he would also ask about the professor who is proficient in gene-targeted therapy.
