Chapter 120: Origin Cells! Universal regeneration of cells!

Stem cell?

Everyone showed expressions of disbelief.

If this were not a research institute led by Academician Jiang, they would simply jump up and scold the liars. Because, stem cells are almost all played by unscrupulous businesses.

Stem cells are the famous origin cells.

It has the potential to proliferate and differentiate, has the ability to self-renew and replicate, and can produce highly differentiated functional cells. There are two types of stem cells in the human body.

One is fully functional stem cells, which can be used to clon the human body directly.

The other is pluripotent stem cells, which can directly copy various organs and repair tissues.

It is precisely because of the anti-heavenly function of stem cells that there are countless technological scams concocted by using it. For example, some wealthy people will spend millions to inject stem cells in the country of Damao in the hope of prolonging their lifespan. This is not bad, at least it is still an injection.

The most outrageous thing is that some unscrupulous merchants have launched oral stem cell products! Take orally?

You heard it right, orally!

There are really people who believe it!

You know, stem cells are also cells, there is no ability to resist stomach acid, and the only end of drinking into the stomach is to be digested by stomach acid.

Oral stem cells are no different from eating steak, because beef is also made of cells!

According to the ideas of these merchants, if you want to live forever in the future, you can fry a plate of sweet and sour stem cells, and then boil a pot of ten complete stem cell soup, and finally dry this cup of stem cell fat house happy water.

In short, most scientists nowadays, as soon as they hear this name, suspect that it is a hoax. Of course, no one dares to say such a thing here in Academician Jiang.

Are there still few outrageous results made by Academician Jiang? Multiple stem cells, it seems to be nothing?

Zheng Hao took the internal lecture PPT, used the pons generation to show everyone a variety of pictures, and explained: “First of all, about the regenerative switch, Western scholars have studied more on salamanders, zebrafish and multi-finned fish before. ”

“These three organisms share the same set of genetic switches, and they are all called by one group.”

The gene regulatory network of “microRNAs”

“Network control, which allows animals such as axolotls to regenerate limbs and body tissues.”

“This discovery means that all three organisms may have inherited the regenerative ability of the same ancestor 420 million years ago, and humans may have inherited some of their genes, but these genes are very inactive in the human body.”

“Of the 10 microRNAs that are important for the regenerative ability of animals such as axolotls, five of which are turned on during limb regeneration and the other five are turned off accordingly.”

“Academician Jiang successfully found this group of genes in the human body and successfully invented the technology of editing switches…”

Just a few words made everyone stunned.

They are all experts in the industry.

However, the more expert you are, the more you can understand the difficulty.

Speaking of which, “finding the gene and successfully editing it” is a two-step process. Very simple?

Wrong!

Researchers who study regeneration and longevity, such as carp crossing the river, are countless. The rich and powerful abroad are particularly fond of investing in related research. MicroRNAs are nothing new, either.

Someone has long found out.

So many people, so long, why did it not bear fruit? Because you really can’t do it.

Not to mention editing, even if you want to find out from 30,000 genes and 3 billion base pairs, it is rare to die. Now, Academician Jiang is engaged in physics and chemistry research, and he has done it all!

How can it not be shocking! Someone unconsciously asked, “How did you find it?” This is also outrageous! ”

Everyone looked at Zheng Hao expectantly.

Zheng Hao also said with a tone of adoration: “Don’t look at me like this, it’s all done by Academician Jiang, it’s really none of my business!” ”

Immediately burst into laughter: “Hahaha! ”

Zheng Hao smiled and said, “Okay, don’t pull it.” I really don’t know, anyway, Academician Jiang just sat in the office for 5 days, found that set of genes, and invented the editing method. ”

“Then, we followed his method and experimented. One success! ”

“Perhaps, this is genius!”

His tone was quite embarrassing. But everyone else felt the same way.

Scientific research is the most intelligent profession in the world.

Ordinary people, even the ability to be cannon fodder is not enough.

……

··· Ask for flowers…

Everyone may have been the pride of heaven everywhere in high school, and they were easily admitted to the “other people’s children” in Qingbei. When I entered college, I found that I was just an ordinary person.

In college, there are talented students who are better than themselves.

The talented students in these universities, after studying for a doctorate from a prestigious university, confidently followed their supervisors into the key laboratory. Then they will find out: “The senior brothers and sisters in the group are all gods!” I’m an idiot! Mentors are not people at all! ”

However, these mentors, who are adored by gifted students, know that they are just ordinary people who follow the direction blazed by scientific geniuses and strive to crawl forward.

A lifetime of desperation may not be able to leave a trace in the history of human science.

From the tutor of a famous school and then up, about 2 or 3 levels, you can reach the level of academician.

For most academicians, the Nobel Prize, or major national scientific research awards, is basically useless. Further up are the winners of various awards, all of whom are the world’s top bulls in various fields. They spend their whole lives and may be able to achieve something in a certain niche.

Even if they reach the level of the world’s top cattle, their lifetime achievements will not have much impact on the world. If you don’t break it and crumple it, ordinary people don’t know what they’re researching.

As for Jiang Fan…

About 3 levels up, or 5 levels?

In short, in the eyes of scientists, Jiang Fan is a god! Zheng Hao continued: “Academician Jiang’s plan is to prepare different pluripotent stem cells for tissues and organs, rather than using full-function stem cells. ”

The difference between these two stem cells, simply put, is: full-function stem cells can differentiate into blood, brain, bone marrow, limbs, organs and other human tissue and organ cells, while pluripotent stem cells can only differentiate into cells of specific tissues.

Normally, fully functional stem cells are obviously a better choice, but there are not many studies on them in countries around the world, so Jiang Fan cannot find a suitable basic technology.

Pluripotent stem cells are different, and the research results have been relatively eight.
