Chapter 54: Potential risks of STAR cells

"Well, it's as easy as a band-aid!"

As he spoke, Zhong Xiongtong raised the radish with tooth marks on his chopsticks towards Lin Xiu, and then smiled at Lin Xiu quite proudly.

"It's amazing technology, no wonder Hideki Calais is so respected!"

"Yes, that's the proudest thing about this technology, because what was originally a promise that required embryonic stem cells can now be realized with the technology of STAR cells. Blood, bones, skin, organs, tissues, and even glands can all be regenerated through STAR cell technology, and if I continue to research in this direction, I may be able to achieve immortality in my lifetime!"

"This ...... It's just science fiction, isn't it?"

"Sci-fi? no...... That's why today's symposium is so eye-catching, and if all goes well with the subsequent surgeries, I think this year's Nobel Prize in Physiology or Medicine will belong to Professor Calais......

"That's amazing, that's a ...... It's amazing!"

"Hmm...... However, I didn't expect that the research progress of the Institute of Physics and Chemistry at Imperial Capital University would suddenly become so fast. After all, just the retinal regeneration technology, Professor Calais's team has been studying it for ten years!"

"Wait a minute, didn't you just say that Professor Hideki Kalai had already implemented this technology on mice ten years ago? Why wait until ten years later to apply this technology to clinical practice? Isn't it...... Did you encounter any difficulties?"

"That's an experimental mouse, not a mouse! And there's a huge gap between theoretical discovery and clinical application. ”

"Huh, what's going on?"

……

Hearing this, Lin Xiuyi suddenly couldn't wait to take out his notebook from the briefcase on the side, and then began to record it seriously.

"If you want to explain it in detail, the experiment that Hideki Kalai tried at Harvard University only demonstrated that STAR cells can differentiate into terminal tissue cells, and the significance of this is that it has opened an unprecedented door for the medical community. But...... What happened to the mouse that was the recipient was not something that Professor Calais had to consider. ”

"You mean that the rat is in danger of health after it has undergone a transplant?"

Professor Calais is a pioneer in the field of regenerative medicine, and what he has done is to prove that the path of STAR cells may work, but how to safely apply them in the field of clinical medicine, and how much potential STAR cells have to develop, is something that his assistants need to study. ”

"Wait a minute, there's one more thing I don't understand, you just said that the rat is in danger of health, may I ask...... What kind of danger is it?"

"This ...... The generation of STAR cells is actually very complex, but if you want to explain it to a layman like you, it is actually to let a virus carrying a transcribed gene infect a differentiating cell, and if successful, the transcribed cell will carry the changed genetic material to continue dividing. STAR cells use this technology to change some specific transcription factors, so that ordinary somatic cells have the same magical ability as embryonic stem cells, but ...... In fact, there are still quite a few risks in this mechanism of action, such as...... Cancer!"

"Cancer......? Does it mean cancer?"

"Hi, some studies have shown that some cancer viruses will write their genetic information into the DNA of this cell after infecting the cell, thus turning normal human cells into cancerous cells, and its mechanism of action is very similar to the principle of Professor Calais to make STAR cells, and we still know very little about the mechanism of cells, so ...... In fact, it is difficult to prove the safety of STAR cells. ”

"So...... This regenerative retinal transplant is another ......"

According to the leaked grapevine, it seems that the differentiated cells are manually checked one by one to ensure that there are no cancerous and undifferentiated cells, but ...... There are also studies that claim that the possibility of STAR cell carcinogenesis is very small, but unfortunately these specific studies are too specialized, and I don't know much about this aspect, so I ......"

"In other words, STAR cells cannot be considered a 100% safe treatment until now, right?"

"100% is too harsh, but it will take a long time to prove that STAR cell therapy is a safe medical treatment. ”

"I see......"

Lin Xiuyi responded thoughtfully, and then silently put away his notes.

……

Lin Xiuyi and Nakakumatong didn't walk out of the izakaya until it was almost closed, and when Lin Xiuyi put his alumnus in a taxi, he breathed a long sigh of relief.

"Sure enough, it needs an answer from people in the industry to understand the doorway! The risk of cancer may be something that Sumitomo Pharmaceutical and the Institute of Physics and Chemistry of Imperial Capital University are trying to deny! Hiccup!"

The breeze was blowing, Lin Xiuyi couldn't help but burp, and then he walked in the direction of the subway station with his briefcase.

Half an hour later, when Lin Xiuyi walked out of Kichijoji Station with the crowd of people who got off work, he couldn't help but take a deep breath after a tired day.

"Whew...... By the way, I think I have to go to the drugstore and buy some groceries for Akemi or something!"

Lin Xiu thought in his heart, so he looked around the street and found that there was a Don Quixote drugstore not far away, so he walked towards the location of the shop.

Speaking of which, the work of procurement on weekdays is basically done by Ling Nai, and now that Ling Nai is not around, Lin Xiuyi naturally has to do these things himself. When he walked into the store, he was first surprised by the variety of products in the store, and then took a leisurely stroll around the store with the purchase box.

"That...... I heard that this brand has become more popular recently!"

"Hey, and Don Quixote has been on sale recently, and the price is a lot cheaper than usual!"

Hearing the word cheap, Lin Xiuyi couldn't help but stop, then turned around and looked towards the place where the voice came from. He doesn't usually come to the drugstore, so he doesn't know what to buy, but he shouldn't be mistaken by looking at the preferences of other customers!

Although the distance was far, Lin Xiuyi still saw the slogan of happiness 0.01 written on the shelf, which made Lin Xiuyi can't help but arouse the curiosity in his heart.

"Buy a few more boxes, it's indispensable anyway!"

"Wait a minute, that guy over there, what a pervert, he just stared at me just now!...... It's disgusting to be smiling at me!"

Eh...... It's really annoying, actually staring at someone in such a place, wait a minute, I'll teach him a lesson for you!

"Forget it, let's change stores!"

……

The couple who were originally picking a happy 0.01 saw Lin Xiuyi standing not far away, and they couldn't help but feel a chill in their hearts, so the two glared at Lin Xiuyi unkindly, and then left here in a panic.

Seeing that the other party left suddenly, Lin Xiuyi stepped forward with some confusion and picked up the happy 0.01 to check it, and at this moment, Lin Xiuyi suddenly understood why the couple looked at him a little strangely just now.

"What, why are the letters mm so small!"
