I Have A Super USB Drive

"How do you feel?"

After visiting the office building of Preston, the chairman proudly said, “Although our company is far behind the global powerhouses like Novartis and Roche, it is also one of the top 100 companies in Zurich.”

"Not bad."

Chen Chen nodded with a smile.

The average Swiss may think 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 five-story small building almost entirely made of glass, placed in Zhongzhou District, which is a standard building in fifth-tier cities.

I am used to seeing the 5A Grade A office clusters with hundreds of floors in business capitals, and Chen Chen didn't say "this soil cultivation room is very delicate", which is very good.

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

However, Chen Chen chose to open a branch in Switzerland not because of the prosperity here, but because of the environmental system in the field of life sciences.

You know, Switzerland has always had the highest cancer survival rate in the world.

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

Compared with other life science bases in the world, Switzerland is more sophisticated in the field of life sciences.

Here are the world's top ten pharmaceutical companies Roche and Novartis, as well as a large number of world-class pharmaceutical companies.

Moreover, these companies eventually formed four "biological valleys" in Switzerland, just like the Silicon Valley in the United States.

The location of Preston is within the Zurich Bio Valley (Zurich).

In the end, the directors of Preston Company led Chen Chen to a similar industrial park in the suburbs outside the city.

It is similar to an industrial park, except that the buildings located here are not all kinds of factories that continue to emit heavy smoke, but rather biological research centers.

"This is the Zurich Bio Valley."

In the northern part of the suburb of Zurich, several cars stopped at the intersection of the road, and a group of people crowded a young man out of the car.

Under the blue sky, Mr. Winn pointed to the scattered buildings in the distance and said loudly, "Although it is not comparable to the huge scale of the Basel Bio Valley which is dozens of kilometers away, the technology of our Bio Valley is also Not to be underestimated."

"The perfect combination of technology and nature, beautiful scenery."

Chen Chen nodded, "I'm here for this."

"Hahahaha!"

Upon hearing this, Mr. Winn finally fell into his stomach, "In that case, then my old man is not too nonsense, let's go directly to the research institute!"

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

The Preston Institute is a small building with only three floors. The whole is dusty. If you only look at it from the outside, there is no connection between this building and life sciences.

But this is also in line with the rigorous and rigid style of Switzerland.

You know, on the Internet, Swiss people have the title of "Mom Force Swiss".

For example: "I parked a car, and the parking space was a bit crooked. That stupid Swiss neighbor actually called the police. Mom, Brian!"

“I found out that I ran out of toilet paper before going to the toilet. I wanted to quickly buy a roll of it in the supermarket, but I didn’t realize until I went downstairs that there was no supermarket in Switzerland. !"

...

In the end, the car stopped in a special parking spot tightly, and several people got off the car one by one, but at this time Wen En couldn't laugh.

Before the research institute, except for a few scattered company personnel, no one else came out to greet him.

"Where's Sam Evan, call him."

Wen En lowly reminded Qian Wenhuan beside him.

"It doesn't matter, Mr. Winn."

Chen Chen said he didn't care, and he walked directly into the institute.

A crowd quickly followed.

It was not until he entered the research institute that Chen Chen saw that in the lobby of the institute, several people in white coats were sitting in front of the bar talking and laughing.

The faces of several directors are even more ugly.

"Where is Sam Evan?" Winn, the general manager, had to stand up, "hasn't he been notified by the company?"

"I'm here, Mr. Winn."

Before Winn finished speaking, a serious blond man walked out of the next room.

Wen En forcefully resisted his anger and said dryly to Chen Chen, "This is Samuel, the head of the institute. He himself has five genetically modified patents and three stem cell patents."

"Mr. Samuel." Chen Chen nodded in greeting.

"Hello, Mr. Chen." Samuel's stiff face squeezed a smile, but no matter how he looked at it, he was a bit arrogant and perfunctory.

Chen Chen shook hands with the other party. He understood that such researchers were treated courteously everywhere, and even some small companies were supported by a few top researchers. The company would collapse once these people left.

Chen Chen had long been informed that Samuel had contributed to the fact that Preston was so big.

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

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

"Our company's main business is the two tissue engineering technologies of'cell anti-aging' and'stem cell anti-aging'. Therefore, the internal laboratories of the institute are mainly cell and stem cell laboratories."

At this time, the commentary was replaced by an employee of the Institute from Wenn, "The laboratories of the Institute have been recognized by the International Laboratory Accreditation Cooperation Organization, and the professionalism is the first level in the world..."

Speaking of this, the employee is very self-confident, "Do you want to take a sample tour or visit by project?"

"I won't go in, just visit through the window."

Chen Chen waved his hand.

Many people always think that the face project is the national conditions of China, but it would be naive to think that there is no face project in foreign countries.

At this moment, I came here with great fanfare. Even if there were hidden dangers in the laboratory, they had been hidden long ago. Even if I checked them carefully, what could I see?

Therefore, Chen Chen didn't mean to visit at all, and instead said, "Tell me about the research results of the laboratory."

The employee was taken aback for a moment, then turned to look at Samuel.

Samuel nodded slightly.

"That's good, but our vocabulary may be a bit professional. If you have any questions you can't understand, just ask."

The researcher thought for a while and said carefully, "In terms of cell anti-aging, we have realized the perfect commercialization of fibroblasts for removing scars and wrinkles. Oh, yes, do you know'fibroblasts'? This is a kind of existence in' The'fibroblast precursor cells' in the'loose connective tissue' evolved, and its main function is to fill the wound tissue defect and heal the wound."

"However, it was discovered 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 skin tissue of 9 cubic millimeters from a human body, and separate fibroblast precursor cells from it. After purification, adding a specific culture medium to differentiate into fibroblasts to proliferate in large numbers, adding a certain amount of trypsin solution and centrifuging several times, the fibroblast suspension can be made."

The researcher looked at Chen Chen slightly proudly, "The advantage of this is that the prepared cells can be passaged no more than 5 times, and they are all in the active phase. Whether it is the function of removing scars or eliminating wrinkles on the human body, it has a certain function. Efficacy."

Chen Chen frowned, "The purification you mentioned in the first step is to use the method of differential separation."

"Uh, indeed..." The researcher nodded subconsciously.

"What is the composition of the specific culture medium?" Chen Chen asked again.

"Yes..." The researcher was taken aback, how could he remember this?

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

Samuel on the side suddenly spoke calmly.

"This plan is good."

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