Chapter 858 The most amazing discovery!

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

Jenny let out a horrified cry.

After all... this is too subversive.

Such a subversion of imagination really made Jenny a little at a loss.

"The split is too fast! It's too fast!"

The corners of Jenny's mouth twitched.

Well, things are a bit different from what I imagined.

When there is enough medium, the growth of these cells is almost crazy...

The nutrients required for cell culture in vitro are basically the same as those in vivo, for example, sugars, amino acids, inorganic salts, growth-promoting factors, trace elements, etc. are required. A culture medium that is strictly formulated with the above-mentioned substances required by cells according to their types and required quantities is called a synthetic medium. Since there are still some components in the internal environment of animal cells that have not been studied clearly, animal serum needs to be added to provide an environment similar to the organism. Therefore, when using synthetic media, it is usually necessary to add some natural components such as serum and plasma.

When cultivating Rebecca's cells, Jenny did the same, and in order to make the nutrient content of the medium reach the most perfect state, Jenny has always been very careful about these tissue cultures.

No... In fact, just these organizations can "survive", which has surprised Jenny.

For the cultivation of body tissues, first get animal embryos or juvenile animal organs and tissues. The material is cut into small pieces and treated (digested) with trypsin (or collagenase) to form dispersed single cells, and the treated cells are transferred to the culture medium to prepare a certain concentration of cell suspension.

The cells dispersed in the suspension quickly adhere to the wall of the bottle and become cell adherents. When the adherent cells divide and grow to contact each other, the cells stop dividing and proliferating, and contact inhibition occurs. At this time, it is necessary to re-treat cells with contact inhibition with trypsin. Then make a certain concentration of cell suspension. In addition, primary culture refers to cell and tissue culture immediately after being taken out of the body. When the cells grow and migrate from animals and plants, form a growth halo and increase, then subculture is carried out, that is, the primary cultured cells are divided into several parts and inoculated into several mediums to make them continue to grow and proliferate.

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

Although it is said to be "cultivation", in fact, Jenny just wants to see what happens when these tissues come into contact with the protein in Catherine's body.

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

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

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

"Can this protein also tell whether the surrounding environment is suitable for growth...?"

Jenny's eyelids twitched.

Throughout the experiment, Jenny did a total of three sets.

The first group is the control group, and the cells on it quickly died out, with no effect at all.

Then there was the second group. This group added the medium, but did not change the medium. After the protein was put in, the cells began to divide vigorously, and then they stopped, even if they Continuing to add protein will not promote the growth of these cells.

The third group is what surprised Jenny the most.

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

This is not the most surprising, but one of her previous verified guesses was the one that stunned Jenny the most.

In tissue cell culture, through certain selection or purification methods, cells with special quality obtained from primary cultures or cell lines are called cell lines. When cultured for more than 50 generations, most of the cells have died of senescence, but some of the cells have undergone changes in their genetic material and have an infinite passage, that is, cancer. The cells at this time are called cell lines.

But at this time, the number of cell divisions Jenny has observed has exceeded 60 generations, and even these tissues alone are as many as several kilograms!

Of course, not all cells have divided so many generations. Every fifteen minutes, these cells will divide for one generation, and after a few generations, these tissues will occupy the entire culture flask. At this time, Jenny will take out some of the tissues and repeat the three experiments.

"If there is no cancer, or even after being separated from the protein, you will also lose life... In other words, such an amazing split is actually caused by Kate's protein..."

Those skins are still skins, without any other changes, and there is no problem even now that Rebecca is completely re-skinned.

This sounds weird, or even crazy, but this is how it is.

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

Jenny suddenly had such an idea.

But she didn't do it like this. Instead, she took out the skin she cultivated from the previous culture medium and spread it out.

At this time, Jenny also discovered an even more shocking thing: the shape of these skin tissues, except for the shape of the skin tissue, was surprisingly similar!

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

"Sure enough, wěn together."

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

"This unscientific!"

Jenny shouted.

This is too exaggerated, right?

It is worth mentioning that Rebecca's skin is now intact, which is also due to 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 healed.

That's it.

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

Thinking of this, Jenny frowned.

Catherine’s cells seem to be able to “recognize” in the same way, even if they have this protein, they will die, but at this time, this cell will remain in its original state, as if it was “frozen”. , But the energy consumption will not be reduced, it is like sitting on the ground waiting for death.

In other words, if you want to cultivate Catherine's cells, you have to "deceive" Catherine's cells themselves.

But these cells seem to produce rejection reactions in the external environment, which makes Jenny a headache.

"...Forget it, let's get Rebecca's experiment first... and then find a way to cultivate some bacteria that have representative xìng..."

Jenny nodded, then the next thing would be easy.

Jenny cut all the previous Rebecca's tissue cells and put them in the culture tank, and then put all the remaining Catherine's protein into it.

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

Taking advantage of this moment, Jenny looked at the other medium, which was the cultivation of plant cells.

This time the experiment was successful, but on the plant cell side, the situation did not exceed Jenny's expectations.

"The cells are all dead, and this enzyme is also effective for plant cells... Then, can it be effective for RNA viruses?"

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

After waiting for about an hour, the skin that has been growing in the culture tank over there seems to have not changed. Jenny was a little suspicious, and then walked over and took the lump—please forgive me for using this adjective— —The skin is taken out from the inside.

"This--"

Jenny's eyes widened.

It turned out that these skins... turned out to look like human skins!

No, that may not be correct, these skins should have grown into the appearance of "Rebecca".

I say this because if Rebecca’s skin is now peeled off her, it will probably look like this, and at this time, Jenny has no doubt that these injured skins can be implanted in Rebecca’s body. Used to replace her skin.

In fact, the truth is easy to understand, Catherine's protein is to restore the cell to its best condition.

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

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

And everything that does not meet this characteristic will be eliminated.

For example, bacteria that invade the human body.

However, Jenny is still not sure about the beneficial bacteria~www.wuxiaspot.com~ We have to do experiments to find out.

"It should be because of some genetic mutation in Catherine, or a certain sleeping gene in her body was alive..."

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

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

Jenny murmured.

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

...

Well, come here to interact. Guess if this section of Catherine’s gene that has been alive allows others to live as well, it will cause a god-horse situation? Hehe~

Three shifts and three shifts!

Roar~
