Chapter 443 (2/2)

Later, we found other evidence to bring the murderer to justice. Only then did we know that the murderer had a bone marrow transplant.

This shows that a person's genes can be changed.

Guo Xiang also went to check it out.

Bone marrow transplantation is generally hematopoietic stem cell transplantation in later generations. Hematopoietic stem cell transplantation usually transplants other people's cells, also known as allogeneic transplantation.

Allogeneic hematopoietic stem cell transplantation requires human leukocyte antigen (HLA) matching between two people. But there are no two people with exactly the same genes in the world. Therefore, after the transplanted cells grow again, their DNA cannot be the same.

Only because the leukocyte antigen is the same, there will be no rejection reaction.

But the DNA of the transplanted cells will not change the genes of the original cells. Therefore, only the DNA of some cells in the blood will be different, but the DNA of somatic cells and germ cells will remain the same.

”So it is!” Gu Xide and Gu Zhennan nodded. Guo Xiang knew so much.

”I can't see why you are so young that you are more powerful than Lu Yuanping, who has been a doctor for decades?” Gu Xide sighed.

Guo Xiang smiled awkwardly. This is what he learned in later generations.

”It's just that I'm good at foreign languages. I read many foreign language books and know more...”

Gu Xide nodded. ”Don't talk about him. Have dinner at home in the evening. I'll ask Aunt Zhang to cook more good dishes.”

”Hey, thank you, grandpa!” Guo Xiang answered happily.

Aunt Zhang was also very happy to hear that. He would not be so lonely if someone accompanied Gu to dinner again.

At dinner in the evening, Guo Xiang said, ”why don't grandpa move to our place? We have a house there. Although we have to go to school during the day, we are at home at night. We can accompany you. We don't trust you to be here alone. ”

And he is old. Unlike Guo Xiang's parents, he is still young. He doesn't have to worry so much.

”Yes, Mr. Gu, you see Zhennan's daughter-in-law's medical skills are so good that you can rest assured that she is around.” Aunt Zhang also advised.

In fact, she just doesn't want to see the old man alone. She is really too lonely. Like a lonely old man, she feels bad for him.

”Grandpa, move over. My mother is gone. I'll honor you for her!” Gu Zhennan also spoke.

Gu Xide heard that his eyes were a little red and nodded. He could not live up to his grandson's filial piety.

”Then move over tomorrow!” Guo Xiang laughed.

”I'll take a day off tomorrow.” Gu Zhennan also said.

”No, no, you're busy. I'll find someone to move by myself. It's not that I can't find anyone.” Gu Sid waved his hand. ”Just leave me a key. I'll arrange it myself.”

”That's OK!” Guo Xiang took out his own key and took down the key to the courtyard door and handed it to Gu Xide. ”You can live in whichever room you like at home, whatever you choose.”

”Good!” A smile appeared on couid's face.

I like the lively and cheerful character of my granddaughter-in-law very much. If my daughter had half of her, she wouldn't be on the dead end.

Nannan's character is a bit like a daughter. Fortunately, he has a good daughter-in-law.

Moreover, just now I saw that she would not suffer from Lu Yuanping, which was also helpful to south south.

It doesn't matter whether he is henpecked or not. As long as he wants to feel happy, it's not a matter.
