Chapter 569 Welcome to join us
Originally, Yang Ping thought that he needed to spend some time chatting with the little guy.

After all, no matter how smart and sensible she is, she is still a ten-year-old girl. She never expected 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 certain pain.

From Sisi, all the cells Yang Ping wanted could be obtained.

Normal mature cells, cells in developing organs, tumor cells, pluripotent stem cells in the bone marrow.

While deciphering the law of cell differentiation, the research on Sisi tumor cells will also be in-depth, and maybe a more advanced treatment plan than targeted therapy can be found.

Yang Ping cheers himself up, it depends on human effort, not to mention that he is not an ordinary person.

Originally, Yang Ping's subject was to cultivate muscle with stem cells, 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 Hayflick's upper limit and slowly undergo apoptosis.

However, in vitro culture cannot naturally provide new cell replacement like the human body, and can only continue to divide by providing more stem cells.

The development of human organs is a kind of natural increase, that is, there is a powerful algorithm in the human body, which can regulate the ratio of newborn and apoptotic cells. The ratio is different between growth and development and adulthood. One is increasing and the other is balanced. Yes, but the mystery of this human algorithm cannot be simulated in vitro.

These mature cells are printed into target organs with a 3D printer, and the cells of these target organs also have the Hayflick upper limit, so it will be a matter of time before they collapse.

This has also become a gap that cannot be bridged by the organs of the human body produced in vitro.

On the contrary, if you find a way to make cells exceed the Hayflick upper limit, these cells will accidentally become tumor cells. They can divide indefinitely, but once unqualified cells appear, they will also divide together. In the end, unqualified cells form malignant tumors.

In a sense, the normal cells of the human body have a lifespan, and they will die after a certain lifespan, so even if there are unqualified cells, they will be lost after all, and will not bring damage to the human body.

If a substandard cell loses its life span, it will divide endlessly and eventually replace a normal organ, disrupting its function.

This is how tumors work.

Therefore, how to achieve a balance between normal cells and tumor cells can find out the locking and unlocking mechanism of their division.

Not only found the key to culturing organs in vitro, but also found the key to tumor treatment.

In this way, whether it is an organ grown in vitro or printed by a 3D printer, it can achieve a certain degree of stability and not collapse like a real organ.

Yang Ping stopped the wheelchair beside the bench and let Sisi blow some fresh air.

He was still thinking about the subject in his mind. The cultivation of stem cells into an organ in vitro faced many difficulties.

There is a need to provide a structural scaffold to support organ function, a supply of professional cells and a supportive environment to allow these cells to repopulate the scaffold and form mature tissues to perform complex organ functions.

Because a certain organ of the human body is only a part of the human body, it accepts the support and constraints of the human body.

To cultivate organs in vitro, it is necessary to simulate all the supports of the human body in vitro.

"Sisi, then you will become the cell warehouse for my brother's research in the future. If you need to take cells, you will need to stick needles on your body at any time, and the needles are very thick and long. Go into the internal organs and steal some internal organs, you have to think about it." Yang Ping took a rest for a while, then pushed Sisi away again.

I 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 cutting with a knife. I could bear it."

Sisi didn't care.

Yang Ping saw Sisi lying on the bed, enduring the pain of the tumor, sweating constantly on her forehead.

"Then we've made a deal and formally invite you to join our scientific research team!"

"Pull the hook!"

The turmoil between the giants and Ruixing is still going on, and it is impossible to pass it so quickly.

For every hospital that rejects giants, there will be no loss. Hospitals generally have several suppliers, and removing one has no effect, and the products of giants are not irreplaceable.

Zimmer for trauma orthopedics, Shufamo for spine, Lin Ke for joints, and a lot of alternative products.

But the giants are different. If they lose the hospital, they will lose the market and the foundation of survival.

Hans lay his head back on the boss's chair and put the towel on his forehead.

I haven't slept all night, and my head is swollen and hot.

I couldn't figure it out all night, it's not logical.

In the industry of orthopedic consumables, he had never seen any storms, and he couldn't figure out how to fight against a little Ruixing, and he fought like this.

Why did my ban on Ruixing cause such a storm.

It can also be explained that Chinese hospitals united to fight back. Those hospitals in Europe, America and Japan followed suit. How can this be explained?

Why?

Hans asked the orthopedic directors of several major hospitals in Mordo to meet and have a chat, but they all said that going abroad for a meeting would not give them any face.

I really want to go up and kick the door!

Lifting the veil on his face and handing it to Richard Chen, Hans took a sip of coffee.

I didn’t eat on an empty stomach in the morning, but I was so hungry that I had no appetite. I couldn’t eat anything at all, so I could only drink cup after cup of coffee to satisfy my hunger.

I have already drank more than a dozen cups of coffee, and my bladder has been emptied several times.

The U.S. headquarters directed all its anger on Hans, and if the current predicament is not resolved, let him pack up and leave.

"Give me an appointment with Ruixing's Mr. Huang!"

Hans sighed, should he bow his head or bow his head, he is a mature man.

"Reply from Ruixing, Mr. Huang has no time to see you!"

Pretending to be a wolf with a big tail, the president of the Asian region of the majestic giant, unexpectedly disappeared, but he had to bow his head under the eaves.

Gan Fengyi has been deeply involved in South China for many years, and she has a personal relationship with Huang Jiacai. Maybe she can ask Huang Jiacai to come out and have a 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 the thinking of the jungle, that is, they are willing to bet and admit defeat.

If he wins, he will ride on your head and oppress you; if he loses, he will lie on the ground and lick you without any embarrassment.

"Get me Gan Fengyi from South China!" Hans said helplessly.

Richard Chen was a little surprised: "You want Gan Fengyi to come forward?"

"If you don't let her come forward, you can handle it?" Hans lost his temper and turned it on Richard Chen.

Richard Chen had no choice but to shut up.

The phone on the desk rang, the phone of the CEO of the headquarters.

"Yes, yes, good, good, good, it must be carried out, it must be done, it must be done!"

Hans stood up immediately as if he was a different person, bowed his waist, and talked into the phone like a pug, with a gentle and pleasant voice.

It seemed that Mr. CEO was right in front of him.

Soon, an apology letter signed by Mr. Hans of the giant company was published on major media.

First of all, we recognize the safety issues raised by major hospitals, sincerely and earnestly improve them, and hope to provide patients with better products.

Secondly, admit that many recent articles slandering the external fixator of the spine were written by Hans personally. Ping's original product was not a plagiarism of the giant's product. At that time, Hans was jealous and organized the media to slander the spinal external fixator.

Finally, the giant stated that the giant and Ruixing are partners and will continue to support free competition. The rumored ban is Hans’ personal behavior. The headquarters has revoked his post in Asia and is under investigation by the headquarters.

After the statement was released in major media, Hans had a high fever for several days.

There is no way, the headquarters of the giant can only give up the soldiers to protect the handsome, and for the benefit of the entire giant, Hans can only sacrifice.

In front of capital, Hans is just a pawn, he puts it on the chessboard when it is useful, and discards it when it is useless.

"What should we do?" Richard Chen was stunned.

Hans put a cold water towel on his forehead: "What else can I do, Gan Fengyi will temporarily take over my position, pack up and pack up, and I will be the president of the African region."

"To Africa?"

"Yes, let's develop business, be content, anyway, I am still a president, and you are still a high-level executive."

Anyway, Hans is a talent, and he helped the giant destroy several companies, and he is also a hero. If it wasn't for a mess, and the matter was too big, it wouldn't be like this.
