Early in the morning, Guan Kou hummed a small song and stepped into the company's door with brisk steps.

This happened to be the peak period of work, and she met many colleagues along the way.

"Good morning, Secretary Guan!"

"Good morning!"

"Secretary Guan is getting better today."

"Thanks"

"Secretary Guan, please approve the budget submitted by our department last time?"

"This must be taken by Mr. Chen, and I will deal with it as soon as possible."

"Okay."

Guan Kou greeted every colleague who talked to her with a smile.

After she walked away, the colleagues behind her whispered: "Hey, do you feel that Secretary Guan is in a particularly good mood today?"

"Yes, Secretary Guan usually has a serious face, but today I suddenly have a smile on my face. I'm still a little uncomfortable."

"It seems that Secretary Guan has encountered some good news. Could it be that he is in love?"

"No, Secretary Guan is so busy every day, so he doesn't have time to fall in love. It should be that something good happened at home."

Just as they were having fun gossiping, Minister Liu of the Executive Minister quietly slipped behind them, coughed lightly, and said with some dissatisfaction: "Okay, okay, I know gossip every day, and I go back to the work station to work!"

As soon as the staff heard the voice of their leaders, they immediately scattered and disappeared into the corridor.

After they all sat back to their workstation honestly, Minister Liu smashed his mouth and muttered to himself with some emotion: "Hey, Secretary Guan looks pretty good when he smiles, and it's more humane."

Guan Kou was in a good mood today because she had obtained the share transfer agreement signed by Chen Changan and went to the Industrial and Commercial Bureau to make notarization.

From now on, she will become a small shareholder of Ruikang Medical.

She owns 2 original shares of Ruikang Medical, even if it is converted from the current net assets of Ruikang Medical, it is worth 20 to 30 million. If the company can go public smoothly, it may expand to more than 100 million.

Guan Kou, who is only 26 years old this year, suddenly realized his financial freedom.

No matter how rational she is and how strong her psychological endurance is, she will inevitably feel joy. In recent days, she has been emitting a sense of happiness all over her body, which has infected many people.

"Sister Kou, take your little sister, I will rely on you to protect you from now on!"

As soon as she walked into the secretary's room, Guan Kou was hugged by Shang Ning who rushed over, and she acted coquettishly for a while.

As Chen Changan's assistant secretary, Shang Ning usually handles the company's documents after she sorts out before handing them to Chen Changan's desk.

So she was the second person in the entire company except Guan Kou who knew that she had obtained shares, which made her envious.

However, Shang Ning could also understand Chen Changan's generosity. Among the three secretaries in their secretariat, it was Guan Kou who had to take care of everything, and Chen Changan also ordered her to deal with a lot of things every day.

Compared to Guan Kou, Chen Chang'an's life secretary Zhang Wenying works extremely easily. He only needs to serve Chen Chang'an tea and water every day, arrange food at meal times, and take care of his daily life. He basically doesn't have to use his brain.

Shang Ning herself just helped Chen Changan sort out documents and helped Guan Kou. Since Chen Changan shifted his focus to the research institute, her assistant secretary has almost become Guan Kou's assistant.

Although the three of them are theoretically at the same level, Guan Kou is actually the core figure of the entire secretariat.

"Okay, let me go quickly, there is still a lot of work to deal with."

Guan Kou broke free from Shang Ning's arms, held the mirror frame, stroked his hair, and tried hard to hide his panic.

"Mr. Chen asked me to contact major venture capital companies and ask about financing matters."

"I'll go to the administrative department to find someone to cooperate with this matter first. You guys are busy first. If Mr. Chen has something to come to me, call me."

After Guan Kou said a few words, he turned around and fled from the secretary's room. She was a little embarrassed and embarrassed. Everyone was a secretary. Suddenly, she was in the hands of the shares and upgraded, which made her feel a little embarrassed to face Zhang Wenying and Shang Ning.

"Tread, step, step."

Guan Kou stepped on his slim heels and walked steadily into the office of the Executive Ministry.

On the other hand, Chen Changan didn't go to the company at all today, but went directly to the research institute.

The hematopoietic stem cell induction project has been underway for almost three months, and the first phase of scientific research is now entering a critical moment.

The team led by Yun Heng has extracted the c-myc gene from mouse cancer cells, but the process of inserting it into hematopoietic stem cells is not going well.

They tried dozens of times. No matter how they did it, as long as the c-myc gene was inserted into the hematopoietic stem cells, the cells would collapse directly and could not maintain stability.

There were several times, Yun Heng successfully inserted the c-myc gene into the hematopoietic stem cells, and the cells did not collapse immediately, but they had a gene mutation!

The mutation of hematopoietic stem cells not only did not become immortal cells, but instead lost the function of division and replication and became a useless cell.

But at least it was a good idea. As long as the cause of the gene mutation can be found and the cells can be reprogrammed, it is possible to perfectly insert the c-myc gene into the hematopoietic stem cells.

Yun Heng is already in the mood.

Chen Changan's work on screening transcription factors is coming to an end. He and his research team have screened out twelve regulatory factors related to cell differentiation functions from the complex genes of hematopoietic stem cells.

Several factors may be present in these twelve regulatory factors, which can differentiate a hematopoietic stem cell into blood cells under the combined effect.

This regulation requires continued attempts to arrange and combine regulatory factors that control differentiate into red blood cells and platelets.

As for the regulatory factors that are converted into other blood cells, we don’t need to worry about it for the time being. At present, Chen Changan mainly wants to realize the artificial batch manufacturing of red blood cells and platelets first.

Excessive blood loss in the human body is generally caused by red blood cells, platelets, and plasma. These three things are more important.

Because 92 is made of water, the remaining part is protein, Chen Changan cannot be artificially manufactured for the time being.

Therefore, only red blood cells and platelets are the key targets of their project.

Laboratory area on the second floor of the institute.

Chen Changan and Yun Heng led two groups of researchers to work hard in two adjacent laboratories.

Yun Heng stood in front of the large projector in the laboratory, holding his chest with one hand, constantly stroking his chin with one hand, looking at the DNA genome of the projected hematopoietic stem cells, and constantly thinking.

Suddenly, his inspiration flashed!

"Without it! If the c-myc gene is inserted into it and reprogrammed between the dr-nr gene and the nbt-y gene, these three genes are connected in series to form an operon structure, and are regulated by the same promoter, they may be able to coexist harmoniously and exert their respective functions."

Thinking of this, Yun Heng waved his fist excitedly, rushed directly to the operating table, took over a researcher's experimental instrument, and began to try to reprogram the hematopoietic stem cells again.
Chapter completed!
