Chapter 858 The most amazing discovery!

"It's different! It's different! It's different!"

Jenny screamed in horror.

After all...this is so subversive of imagination.

Such an unimaginable thing really made Jenny a little overwhelmed.

"It's splitting too fast! It's too fast!"

The corners of Jenny's mouth twitched.

Well, things are really a little different from what I imagined.

With enough culture medium, these cells grow like crazy...

The nutrients required for cell culture in vitro are basically the same as those in the body. For example, sugars, amino acids, inorganic salts, growth-promoting factors, trace elements, etc. are required. The above-mentioned substances required by the cells are strictly formulated according to their types and required quantities.

The base is called a synthetic medium. Since some components of the internal environment of animal cells have not yet been clearly studied, animal serum needs to be added to provide an environment similar to that of living organisms. Therefore, when using synthetic culture media, serum is usually added.

Some natural ingredients such as plasma.

When cultivating Rebecca's cells, Jenny did the same thing. In order to achieve the most perfect nutritional content of the culture medium, Jenny has always been very attentive to cultivating these tissues.

No...in fact, just the fact that these organizations can "survive" already surprised Jenny.

To culture body tissues, first remove animal embryos or young animal organs and tissues. Cut the materials into pieces and treat (digest) them with trypsin (or collagenase) to form dispersed single cells, and then move the processed cells into culture

A cell suspension of a certain concentration is prepared in the base.

The cells dispersed in the suspension quickly adhere to the bottle wall and become cell adherents. When the adherent cells divide and grow until they are in contact with each other, the cells will stop dividing and proliferating, and contact inhibition will occur. At this time, contact inhibition needs to occur.

The cells are re-treated with trypsin and then prepared into a cell suspension of a certain concentration.

In addition, primary culture is cell and tissue culture performed immediately after being removed from the body. When cells grow and migrate from animals and plants, form growth haloes and increase in size, then subculture is performed, that is, the primary cultured cells are divided into several parts.

Inoculate it into several portions of culture medium to allow it to continue growing and multiplying.

But the tissues in Rebecca's body were different. These tissues were just some skin cells taken out by Jenny.

Although it was said to be "cultured", in fact, Jenny just wanted to see what would happen to these tissues when they came into contact with the proteins in Catherine's body.

Because judging from the previous situation, Catherine's protein should be able to have some impact on these tissues, but I am not entirely sure what it is specifically.

But now, it's different. When Rebecca's skin cells received Catherine's protein, they were indeed confused at first, and then promoted the growth of these cells.

But Jenny didn't expect that these cells would divide so quickly!

"Could this protein also be able to tell whether the surrounding environment is suitable for growth...?"

Jenny's eyelids twitched.

In the entire experiment, Jenny did three groups in total.

The first group is the control group. The cells on it died quickly and there was no effect at all.

Then there is the second group. This group added the culture medium, but did not change the culture medium. After adding this protein, these cells stagnated after vigorous division at the beginning, even if they themselves

Continuing to add protein will not promote the growth of these cells.

The third group was what surprised Jenny the most.

Here, Jenny changes the culture medium every two hours, which keeps the cell division at a very vigorous stage.

This was not the most surprising thing, but a certain verified guess of hers before was what stunned Jenny the most.

In tissue cell culture, cells with special properties obtained from primary cultures or cell lines through certain selection or purification methods are called cell strains. When cultured for more than 50 generations, most cells have aged and died.

, but there are still some cells that have undergone changes in genetic material and have the characteristics of unlimited passage, that is, cancer. The cells at this time are called cell lines.

But at this time, the number of cell divisions that Jenny observed had exceeded 60 generations, and even these tissues alone already amounted to several kilograms!

Of course, not all cells divide for so many generations. Every fifteen minutes or so, these cells will divide for one generation, and after a few generations, these tissues will occupy the entire culture flask. At this time, Jenny

Part of the tissue will be removed and three sets of experiments will be repeated.

"It is not cancerous, and even after being separated from the protein, it will lose its activity... In other words, such amazing dividing characteristics are actually caused by Kate's protein..."

Those skins are still skins, there are no other changes, and even now Rebecca is completely reskinned without any problem.

This may sound unbelievable, even crazy, but that's how it is.

"Wait a minute, what would it look like if these skins were allowed to grow in a normal environment?"

Jenny suddenly had such an idea.

However, she did not do this. Instead, she took out the skin she had cultured from the previous culture medium and spread it out.

But at this time, Jenny also discovered something even more shocking: except for the shapes of these skin tissues, which were cut off by herself, the shapes were surprisingly similar!

Jenny walked up to Rebecca, then looked at Rebecca and compared a piece of skin with Rebecca's arm.

"It really matches."

This place is where Jenny took away Rebecca's skin, and at this time, these tissues also extended from the wound, just like human skin - but speaking of it, it was originally human skin.

"This is unscientific!"

Jenny shouted.

Isn't this too exaggerated?

It is worth mentioning that the skin on Rebecca's hands is now intact, which is also because of Catherine's protein.

In fact, just two hours ago, Jenny sprayed these protein solvents on the wound. After that, the skin of the wound began to proliferate and then heal.

That's it.

"What if...it's Kate's own cells..."

Thinking of this, Jenny frowned.

Catherine's cells seem to be able to "recognize" them as well. Even if they have this protein, they will die, but at this time, the cells will maintain their original state, as if they were "frozen"

, but the energy consumption will not be reduced, it is like a person sitting on the ground waiting to die.

In other words, if you want to cultivate Catherine's cells, you must also "cheat" Catherine's cells themselves.

However, these cells seemed to produce a rejection reaction when exposed to the external environment, which gave Jenny a headache.

"...Forget it, let's finish Rebecca's experiment first...and then find a way to get some representative germs for culture..."

Jenny nodded, then the next thing would be easy to handle.

Jenny cut up all of Rebecca's tissue cells and put them into a culture vat, and then put all the remaining Catherine's proteins into them.

Sure enough, at this time, these cells began to fuse together, and these skin cells began to undergo drastic changes. Jenny even seemed to see these cells "squirming"!

Taking advantage of this moment, Jenny looked at the other culture media, which contained plant cell culture.

This experiment was successful. On the plant somatic cell side, the situation was not beyond Jenny's expectations.

"All the cells died. This enzyme is indeed effective on plant cells... So, can it be effective on RNA viruses?"

Jenny suddenly thought that she seemed to have to find a way to get some viruses...

After waiting for about an hour, the skin that had been proliferating in the culture tank over there seemed to have not changed. Jenny was a little confused, and then walked over and removed the lump - please forgive me for using this adjective -

The skin was taken out from inside.

"this--"

Jenny's eyes widened.

It turns out that these skins... actually grew into human skin!

No, that may not be correct. These skins should look like "Rebecca".

I say this because if Rebecca's skin was peeled off her body now, it would probably look like this. At this time, Jenny had no doubt that the injured skin could be implanted into Rebecca's body.

Used to replace her skin.

In fact, the truth is easy to understand. Catherine's protein is to restore cells to their optimal state.

At this time, similarly, telomeres will return to their optimal state.

It's like the system has turned on mirroring. No matter what the state is, you can use this "ghost" system to restore it to the time when the mirror was just installed - that is, when cells are most vital and the human body is most vital.

And anything that does not meet this characteristic will be excluded.

Just like bacteria that invade the human body.

However, Jenny still doesn’t know much about beneficial bacteria, and experiments will be needed to find out more about this.

"It should be that Catherine has some genetic mutation, or that a sleeping gene in her body has been activated..."

If this is the case, everything can be explained smoothly, and it seems to be clear at a glance what the thing is like.

"It seems like something terrible has been discovered..."

Jenny muttered.

She didn't know that because of the discovery of this thing, the history of the entire world would undergo major changes...

…

Well, let’s interact here. Guess what will happen if Catherine’s activated gene is activated by others? Hehe~

Three updates, three updates!

Hoho~
