Chapter 1008

Yang Rui returned to the ion channel laboratory in spring, surrounded by people saying hello.

Yang Rui also nodded slightly in response, like an old leader.

"Director Yang, 60 groups of half embryos, all ready." Gu Qiang bumps over from the side and blocks a group of scientific research Wang who is preparing to say hello.

Wang Lei and others glared at Gu Qiang's back.

How hard it is for a research dog to express his existence.

Gu Qiang has no sense of it, and his whole body is full of decadence. His stubble beard easily reminds people of down and out people and sports artists. What's more surprising to the biologists is that in only two days, how can a person's beard grow so long?

"Finished 60 groups, not bad." Yang Rui stopped and nodded to Gu Qiang with a satisfied expression. Then he continued to walk forward and said, "then we will go on to the next step."

"That's it?" Gu Qiang was stunned.

It took him nearly two days to complete the 60 groups of embryos required by Yang Rui.

Isn't Yang Rui supposed to show shock or disbelief?

Gu Qiang stares at Yang Rui.

Yang Rui inexplicably looked back at Gu Qiang and asked, "what are you doing here? Time doesn't wait. "

"All right." In Gu Qiang's heart, Teddy is jumping and asking, "what experiment do you want to do next?"

"Freeze the embryo." Yang Rui's answer is very simple.

In Gu Qiang's heart, Teddy suddenly wakes up and runs madly for 30 times. Gu Qiang Cai asks with a strange smile: "frozen embryo? Do you want to do frozen embryo experiment? Shouldn't these 60 groups of embryos be transferred first? "

"30 groups were treated with embryo transfer, and the remaining 30 groups were treated with embryo freezing and thawing transfer." Yang Rui's order is very clear.

Gu Qiang felt that Yang Rui was confused and had to argue again: "you are doing two groups of experiments. Besides, there is no precedent for frozen embryo project in China, right?"

At this point, Gu Qiang suddenly calmed down.

There have been a lot of experiments in China, such as embryo transfer after embryo segmentation. The 1970s was a period of great development of embryo transfer, and the 1980s was a period of very lively competition. It was very common for you to sing and I came on stage.

The Americans have done the mouse embryo transfer, the British will do the rabbit embryo transfer, and in a twinkling of an eye, the French will do a goat embryo transfer to show

The same is true in China. At the end of 1970s and the beginning of 1980s, China's genetic engineering field was not able to participate in the international competition. However, who can rescue and repeat the foreign experiments is also an achievement.

The Chinese Academy of Sciences is the first to complete the mouse embryo transfer. Peking University will try its best to do the rabbit embryo transfer. After Fudan, it's normal to catch sheep and raise them in the dormitory

From Gu Qiang's point of view, he has participated in all these activities, just because the team is weak and the resources are scarce. He has never gone too far.

However, just because he didn't eat too much doesn't mean that he is not familiar with these experiments. In fact, Gu Qiang repeated some experiments later, which is also his strength and main achievement.

Yang Rui asked him to do 60 groups of embryo segmentation. Although some of the techniques are not satisfactory, Gu Qiang is confident that after transplantation, the semi embryos separated by himself will still have a relatively high survival rate.

Frozen embryos, however, are another concept.

Apart from that, the equipment needed to freeze embryos keeps most laboratories out of the door.

Up to 85 years ago, there was no successful precedent of frozen embryo and transferred pregnancy in China, and it was rare in foreign countries. Only a few laboratories could complete it.

In terms of performance, freezing embryos is a very science fiction thing.

It's understandable to store an animal embryo at 4 ℃ to 0 ℃. After several months of storage at minus 80 ℃, thawing and transplanting it into the animal body, it can even give birth to a young animal. It's a bit imaginative. When the embryo is stored in liquid nitrogen at minus 196 ℃ for several years or even longer, the transplant recipient can still get pregnant, This has been out of the normal thinking boundaries.

You know, animal embryos are living.

Living animal embryos can be preserved at minus 196 ℃ for a very long time and resurrected. Can living humans reproduce this technology? Although the idea of frozen human resurrection could not be realized until 30 years later, we can imagine the shock caused by the first successful frozen embryo transfer in the scientific community and social environment.For the domestic biological, scientific and press circles, frozen embryo transfer has always been an attractive carrot.

Gu Qiang was once tempted by this carrot, but he had no money and no one, so he just thought about it.

Yang Rui has money and people.

Gu Qiang also thought that if Yang Rui had made sufficient preparations, he would not be able to challenge this topic.

What he didn't expect was that Yang Rui put forward this topic so quickly, and there was no preparation at all.

Shouldn't we kill chickens and sheep and sacrifice three animals before trying to operate such a big project in the form of demonstration and conference?

Gu Qiang looks at Yang Rui with a strange suspicion.

Yang Rui didn't notice his eyes at all. While doing routine examination, he said: "I don't care if there is any precedent of freezing embryos in China. We just do our own. It's really a hurry to do two groups of experiments at the same time. You can choose one group to do it, and the other group, I'll find someone else to do it. "

"No, I can do it." Gu Qiang then asked, "how much money are you going to spend on these two sets of research?"

Money is the last word, and to complete the first case of frozen embryo transfer in China, the necessary funds are indispensable.

Yang Rui didn't answer directly, but turned around and asked, "Lao Xu, how much is on the account of the genetic engineering laboratory?"

"Tens of thousands. What's the matter? " At present, Xu Zhengping helps Yang Rui to manage the genetic engineering laboratory part-time. After all, Gu Qiang is the only researcher in this laboratory whose basic construction has not yet been completed.

Yang Rui nodded and said, "I'm going to do frozen embryo transfer. You can sort out the funds and help me put them forward."

"Good." Xu Zhengping did not have a stumbling promise to come down.

"Ha ha, ha ha, ha ha..." Gu Qiang's rebellious nature suddenly broke out. He burst out laughing with his stomach and pointed to Yang Rui and Xu Zhengping, saying: "I'll tell you a joke. I have tens of thousands of yuan. I want to do an experiment of frozen embryo transfer... Ha ha, ha ha ha, Ha ha... "

Brothers, it's slower. Don't blame me, because my wife asked me to take her to play "Longwu 2", which can't be coded. My sister-in-law leads the team. If you dare to join the gang, please go to [Shenzhou] district and join me to form an army of Zhiniao. Don't wait here.
