"How's it going, how does it feel?"

After visiting the office building of Preston, the chairman proudly said, "Although our company is far from being as strong as the world's leading companies such as Novartis and Roche, it is also one of the top 100 companies in Zurich." ”

"Not bad."

Chen Chen nodded with a smile.

Ordinary Swiss people may think that Chen Chen thinks it is really good, and only Qian Wenhuan can understand Chen Chen's feelings.

The so-called Preston office building is actually a small five-story building made almost entirely of glass, which is the standard building in the middle of the continent, which is a fifth-tier city.

Accustomed to seeing the 5A Grade A office building cluster with hundreds of floors in Shangdu at every turn, Chen Chen didn't say "This earthen culture house is very exquisite", which was very face-saving.

In addition to the good air and the exotic atmosphere of the city, Zurich is indeed the size of a fifth-tier city.

However, the reason why Chen Chen chose to open a branch in Switzerland is not because of the prosperity here, but because of the general environment and system in the field of life sciences.

Switzerland has always had the highest chance of surviving cancer in the world.

The reason is that Switzerland has world-renowned biology universities, many pharmaceutical companies that focus on scientific research, and a large number of highly qualified life science researchers.

Compared to other life sciences sites in the world, Switzerland is more cutting-edge in the field of life sciences.

There are the world's top 10 pharmaceutical companies Roche and Novartis, and a large number of world-class pharmaceutical companies.

Eventually, these companies formed four "bio-valleys" in Switzerland, just like the Silicon Valley in the United States.

Preston is located in the BioValley Zurich.

Eventually, the Preston directors led Chen to an industrial park-like area on the outskirts of the city.

Similar to the industrial park, except that the buildings here are not factories with smoke but biological research centers.

"This is the Zurich Bio Valley."

In the northern part of the Zurich suburb, several cars were parked at the intersection of the road, and a crowd of people gathered around a young man and stepped out of the car.

Under the blue sky, Mr. Wynn pointed to the scattered buildings in the distance and said loudly, "Although it is not as large as the Basel Biovalley dozens of kilometers away, the technology of our Biovalley should not be underestimated. ”

"The perfect blend of technology and nature, a beautiful view."

Chen Chen nodded, "That's what I'm here for." ”

"Hahahaha!"

When Mr. Wen heard this, his heart finally fell into his stomach, "In that case, then my old man doesn't have much nonsense, let's go directly to the research institute!" ”

With that, several people got into the car again and went straight to the Life Science Research Institute of Preston Company.

The Preston Institute is a small three-story building with so much ash that if you look at it from the outside, you can't see any connection between the building and the life sciences.

However, it is also in line with the strict and rigid style of Switzerland.

You know, on the Internet, the Swiss have the title of "Mama".

For example: "I parked a car, the parking space was slightly crooked, and that stupid Swiss neighbor called the police, mom Rui!"

"Before going to the toilet, I found that the toilet paper was used up, and I wanted to buy a roll in the supermarket quickly, but I didn't realize that there was no supermarket open on Sunday in Switzerland, and in the end I had to drive ten kilometers to the train station to buy it.

……

In the end, the car stopped in a special parking space, and several people got out of the car one by one, but at this time Winn couldn't laugh.

In front of the institute, except for a few scattered company personnel, no one else came out to greet them.

"Sam Evan, call him."

Wen En reminded Qian Wenhuan beside him in a low voice, and then smiled apologetically at Chen Chen, "I'm sorry, I think it should be our great scientists who forgot to sleep and eat because of their research." ”

"It's okay, Mr. Winn."

Chen Chen said that he didn't care, and at the same time walked directly towards the research institute.

A group of people hurriedly followed.

It wasn't until he entered the research institute that Chen Chen saw that in the hall of the research institute, several people in white coats were sitting in front of the bar, talking and laughing.

The faces of several directors became even more ugly.

"Where's Sam Evan?" As the general manager, Wen En had to stand up, "Didn't he receive a notice from the company?"

"Here I am, Mr. Winne."

Before Wynn could finish speaking, a blonde man with a serious face walked out of the next room.

Wen En held back his anger and said dryly to Chen Chen, "This is Samel, the head of the research institute, who has five genetically modified patents and three stem cell patents. ”

"Mr. Samel." Chen Chen nodded in acknowledgment.

"Hello, Mr. Chen." A smile erupted from Samel's stiff face, but it was somewhat arrogant and perfunctory no matter how you looked at it.

Chen Chen shook hands with the other party, he understood that this kind of researcher was courteous everywhere he went, and even some small companies were supported by a few top scientific researchers, and as soon as these people left, the company would collapse.

And Chen Chen had already gotten the news that the reason why Preston Company was able to do so big today was due to Samel's contributions.

However, it seems that this person in charge is already a little arrogant because of his high merits.

After everyone finished the introduction, accompanied by a group of people, Chen Chen began to visit the institute again.

"Our company's main business is 'cell anti-aging' and 'stem cell anti-aging' two tissue engineering technologies, so the laboratory within the institute is also dominated by cell and stem cell laboratory."

At this time, the narrator was replaced by Wen En to an employee of the institute, "The laboratories of the institute are all accredited by the International Laboratory Accreditation Cooperation Organization (ILAC), and their professionalism is the first level in the world......

Speaking of this, the employee said confidently, "Would you like to visit by sample or by project?" ”

"I'm not going in, just look through the window."

Chen Chen waved his hand.

Many people always think that the face project is the national condition of Central, but it would be naïve to think that foreign countries do not have face projects.

At this time, I came over with great fanfare, even if there were hidden dangers in the laboratory, they had already been hidden, even if I checked carefully, what could I see?

Therefore, Chen Chen didn't want to visit at all, and instead said, "Let's talk about the research results of the laboratory now." ”

The employee was stunned and turned to look at Samel.

Samel nodded slightly.

"That's fine, but our vocabulary may be a bit specialized, so if you have any questions that you don't understand, just ask."

The researcher thought for a moment and said carefully, "In terms of cell anti-aging, we have achieved the perfect commercialization of fibroblast scar removal and wrinkle removal, oh yes, do you know 'fibroblasts'? This is a kind of 'fibroblast precursor cell' that exists in the 'loose connective tissue', and its main role is to fill the wound tissue defect and heal the wound. ”

"However, it has been studied a long time ago that collagenase secreted by fibroblast precursor cells has the ability to remodel tissues, so we only need to extract a piece of 9 cubic millimeters of skin tissue from a human body, isolate fibroblast precursor cells from it and purify it, and then add a specific culture medium to differentiate it into fibroblasts and proliferate a lot, and then add a certain amount of trypsin solution for multiple centrifugations to make a fibroblast suspension."

The researcher looked at Chen Chen with a little pride, "The advantage of this is that it can ensure that the number of passages of the prepared cells does not exceed 5 times, and all of them are in the active period, whether it is for the removal of scars or the elimination of wrinkles in the human body, they have certain curative effects." ”

Chen Chen frowned, "The purification you mentioned in the first step is to use the differential speed removal method. ”

"Well, that's true...... the researcher nodded subconsciously.

"What is the composition of that particular culture?" Chen Chen asked again.

"Yes......" The researcher was stunned for a moment, how could he possibly remember this?

"It is to add 15% fetal bovine serum to a non-autoclavable MEM cell culture."

Samel on the side suddenly spoke calmly.

"That's a good plan."

Chen Chen nodded, "But I think fetal bovine serum can be increased to 30%, and in addition, 3.5g/L glucose and 50mg/L human insulin can be added." ”
