Originally, Yang Ping thought he needed to take some time to have a good chat with the little guy.
After all, no matter how smart and sensible she is, she is still a ten-year-old girl. I didn’t expect the little guy to agree so readily.
During the experiment, various tissue cells need to be extracted repeatedly, and various punctures are inevitable. Even with local anesthesia, punctures will cause a certain amount of pain.
From Sisi, you can get all the cells Yang Ping wants.
Normal mature cells, cells in developing organs, tumor cells, and pluripotent stem cells in the bone marrow.
While deciphering the rules of cell differentiation, we will also conduct in-depth research on Sisi tumor cells, and perhaps we can find a more advanced treatment plan than targeted therapy.
Yang Ping cheered himself up, it all depends on people, not to mention he is not an ordinary person.
Originally, Yang Ping's topic was stem cell culture of muscle, which had nothing to do with Sisi's condition.
However, after stem cells differentiate into target organ cells, these mature cells fall into the lock of Haiflik's upper limit and slowly undergo apoptosis.
In vitro culture cannot naturally provide new cell replacements like the human body, and can only rely on providing more stem cells to continue dividing.
The development of human organs is a natural increase. That is to say, the human body has a powerful algorithm that can regulate the ratio of new and apoptotic cells. During growth and development, this ratio is different from that in adulthood. One is incremental and the other is balanced.
Yes, but the mystery of this human algorithm cannot be simulated outside the body.
Use a 3D printer to print these mature cells into target organs. The cells of these target organs also have the Hayflik upper limit, so collapse will happen sooner or later.
This has also become a gap that cannot be crossed by organs produced outside the body.
On the contrary, if you find a way to make cells break through the Hayflick limit, these cells will accidentally become tumor cells. They can divide without limit, but once unqualified cells appear, they will also divide along with them. In the end, unqualified cells will
It forms a malignant tumor.
In a sense, normal cells in the human body have a lifespan and will undergo apoptosis after a certain lifespan. Therefore, even if there are substandard cells, they will eventually be lost and will not cause damage to the human body.
If an unqualified cell loses its lifespan limit, it will divide endlessly and eventually replace a normal organ, destroying its function.
This is the mechanism of tumors.
Therefore, how to achieve a balance between normal cells and tumor cells can help us find out the locking and unlocking mechanisms of their division.
Not only did we find the key to cultivating organs in vitro, but we also found the key to tumor treatment.
In this way, whether organs are grown in vitro or printed with a 3D printer, they can achieve a certain degree of stability and not collapse like real organs.
Yang Ping stopped the wheelchair beside the bench and let Sisi blow some fresh air.
He is still thinking about the subject in his mind. He faces many problems when cultivating stem cells into an organ outside the body.
It is necessary to provide a structural scaffold to support the function of the organ, a supply of professional cells, and a supportive environment so that these cells can repopulate the scaffold and form mature tissues to perform complex organ functions.
Because a certain organ of the human body is just a part of the human body, it accepts the support and constraints of the human body.
To cultivate organs outside the body, it is necessary to simulate all the support of the human body outside the body.
"Sisi, then you will become the cell warehouse for my brother's research in the future. If cells need to be taken, a needle will be inserted into you at any time. Moreover, the needle is very thick and long. Sometimes it penetrates into the bone marrow and extracts it, and sometimes it needs to be stabbed.
You have to think carefully about entering the internal organs and stealing some internal tissue." Yang Ping rested for a while, then pushed Sisi away.
We walked around the hospital a few times and bought an ice cream for the little guy from a canteen.
"I'm not afraid. In the past, when the tumor hurt, it was like a knife cutting me. I could bear it."
Sisi doesn’t care.
Yang Ping saw Sisi lying on the bed, enduring the pain of the tumor, sweating constantly on her forehead.
"Then we have decided to formally invite you to join our scientific research team!"
"Hook!"

The turmoil between the giants and Ruixing is still going on, and it cannot be over so quickly.
For every hospital that rejects the giants, there will be no losses. Hospitals generally have several suppliers, and removing one will have no impact, and the giants' products are not irreplaceable.
Zimai in traumatology and orthopedics, Pivotal model of spine, Linke in joints, and a lot of alternative products.
The giants are different. If they lose the hospital, they will lose the market and the basis for survival.
Hans lay half-ly on the boss's chair with his head raised, and this towel was placed on his forehead.
I didn't sleep that night, and my head felt swollen and hot.
I didn't figure it out all night. This is not logical.
In the industry of orthopedic consumables, he has never seen any turmoil, and he can't figure it out. How can he end up fighting like this with a small Ruixing?
Why did my ban on Rui Xing cause such a turmoil?
It can also be explained that Chinese hospitals unite to fight back, but those European, American and Japanese hospitals join in the fun. How can this be explained?
What’s the explanation?
Hans made an appointment with the directors of orthopedics at several major hospitals in the city to meet and chat, but they all said they were attending meetings abroad and would not give him any face.
I really want to go up and kick in the door!
Lifting the veil on his face and handing it to Richard Chen, Hans took a sip of coffee.
I had an empty stomach in the morning and didn't eat anything. I was so hungry that I had no appetite and couldn't eat at all. I could only drink cup after cup of coffee to satisfy my hunger.
I have drank more than ten cups of coffee and my bladder has been emptied several times.
The U.S. headquarters will direct all its anger at Hans and will let him pack up and leave if the current predicament is not solved.
"Give me an appointment with Mr. Huang from Ruixing!"
Hans sighed, should he bow his head or bow his head? He is a mature man.
"Reply from Ruixing, Mr. Huang doesn't have time to see you!"
Why are you pretending to be a big-tailed wolf? The dignified CEO of the Asian region of the giant is actually missing, but he has to bow his head when he is under the eaves.
Gan Fengyi has been involved in South China for many years and has a personal relationship with Huang Jiacai. Maybe she can ask her to make an appointment with Huang Jiacai so that they can come out and talk.
Hans felt a dull pain in his heart and felt a sense of shame, but the current situation could only be like this.
Westerners have a law of the jungle mentality, that is, they are willing to gamble and admit defeat.
If he wins, he will sit on your head and oppress you; if he loses, he will lie on the ground and lick you, without any embarrassment.
"Pick me up Gan Fengyi from South China District!" Hans was helpless.
Richard Chen was a little surprised: "You want Gan Fengyi to come forward?"
"If you don't let her come forward, can you handle it?" Hans was full of temper and took it out on Richard Chen.
Richard Chen had no choice but to shut up.
The phone on the desk rang. It was the CEO of the headquarters.
"Yes, yes, good, good, good, we must implement it, we must, we must!"
Hans stood up immediately as if he was a different person, hunched over, and spoke to the phone like a pug, with a gentle and pleasant voice.
It was as if the Mr. CEO was right in front of him.
---
Soon, an apology letter signed by Mr. Hans from the giant company was published in major media.
First of all, I would like to express my recognition of the safety issues raised by major hospitals, sincerely and conscientiously make improvements, and hope to provide patients with better products.
Secondly, he admitted that many recent articles that slandered the spinal external fixator were written under Hans' personal instructions. The headquarters has launched an investigation and will deal with it seriously. He also apologized to Ruixing Company and the inventor, and then explained eloquently that the spinal external fixator
It is Yang Ping's original product, not a plagiarized giant product. In a jealous mood at the time, Hans took the initiative and organized the media to slander the spinal column external fixator.
Finally, Giant stated that Giant and Ruixing are partners and will continue to support free competition. The rumored ban is Hans's personal behavior. The headquarters has revoked his appointment in Asia and accepted the investigation from the headquarters.
After the statement was released by major media, Hans had a high fever for several days.
There is no other way, the giant headquarters can only sacrifice soldiers to protect the commander. For the benefit of the entire giant, Hans can only sacrifice.
In front of capital, Hans is just a chess piece. If it is useful, put it on the chessboard, and if it is no longer useful, throw it away.
"What should we do?" Richard Chen was affected.
Hans put an ice-water towel on his forehead: "What else can I do? Gan Fengyi will temporarily take over my position. Pack up my things and I will take over as the president of Africa."
"Go to Africa?"
"Yeah, just be content with your business development. After all, I'm still the president, and you're still a senior executive."
After all, Hans is a talented person. He helped the giants destroy several companies and was also a hero. If it hadn't been for a pile of chicken feathers and the matter was too big, it wouldn't have been like this.
