Xiang Shan looked at Nyaguti in shock: "You mean, such embryos can survive? Animals and plants mixed together?"

"In the embryonic stage, the organism is just a cluster of cells, and the tissues have just begun to differentiate." Nyaguti spread her hands: "Because the volume is small enough, it is enough to rely on the cells to passively absorb the surrounding nutrients, even if the organs are not differentiated. Survival. However, with the process of organ differentiation, organisms that are too far apart will most likely have problems."

Xiang Shan patted head: "This is... it's sci-fi?"

"Science fiction shit." Yoggmov said disdainfully: "The research that we have started several decades before we were born, do you tell me about science fiction? Steampunk?"

"strictly speaking...um. "Niya Guti said: "Since the 1970s, scientists from all over the world have been studying heterogeneous chimeras, such as sheep-goat chimeras and rat-mouse chimeras. At the beginning of the 21st century, they mainly studied human- Animal chimera, hoping to create an animal that can provide organ transplantation. The one that we have cooperated with in the case of'monkeys'... the primate translational medicine research institute in central Yunnan, embedded primates The research on fusion is quite famous."

Xiang Shan was shocked again: "Is there a crouching tiger hidden dragon in our cooperative organization so far? No...this research is so early..."

He really feels that this kind of painting style is a bit sci-fi, only after Yoggmov made a major breakthrough in basic theory.

"The grafted plant is a kind of chimera. In fact, this phenomenon was first recorded by horticulturists." Niyaguti shook his head: "Don't talk about plants. In the animal kingdom, natural inlays Combinations also exist-including humans. In the mother's womb, fertilized eggs occasionally develop into different embryos, and then these embryos may reintegrate together before a certain stage. Many people are natural chimeras, only But they will never know for the rest of their lives."

"Of course, occasionally there will be more peculiar conditions-for example, some people's reproductive organs happen to come from their fraternal twin brothers and sisters. When people do a paternity test, they will always come to the result that'this child's biological father is my brother's brother'."

"Compared with me, there is almost no such research. Technical content." Yoggmov snort disdainfully on this: "In fact, the chimera research is based on the immune system that has not yet been launched that's all. I remember that the human-monkey chimera in vitro embryos had to be all executed 20 days ago, right? Then some research showed that , The fetus cannot detect the traces of dendritic cells until after Twelfth week."

"And at this stage, the dendritic cells of the fetus are not used to resist the outside world, but to inhibit itself. Immune cells are generated to prevent their own immune function from attacking each other."

Dendrite cells, a type of immune cell responsible for antigen presentation, can efficiently ingest, process, and present antigens. , Responsible for activating the initial T cells, in the central link of initiating, regulating and maintaining the immune response.

"In short, in order to avoid miscarriage, the immune system during embryonic development is in the'exempt period.' At this time, almost all things touched will not trigger an alarm. So-called chimeras survive in this way. "Yoggmov continued: "In fact, this "weak alarm" condition will continue to a certain extent until the baby is born. It is theorized that some people are prone to allergies because the period is too high. It’s clean, and the immune system’s whitelist is not long enough."

Xiang Shan feels that his hygiene concept has been subverted: "So, "I don’t know how to eat, I’m not sick". Based on?"

Niyaguti reminded: "Only infants and young children... and this also means that they are easy to pull the truly dangerous pathogens into the whitelist, and childhood may become sickly. "

Here, Xiang Shan probably understands what Yoggmov means.

"You mean..."

"This is the optimal C plan." Yoggmov said: "Find a way to reverse the life cycle of the immune system and let the immune system temporarily return 'Embryonic stage'. The medicine required by this technology is a variety of dedifferentiation-inducing signal molecules for immune cells. They are responsible for typing instructions to the immune system-recalling the'embryonic development state'."

Niyaguti pondered for a moment: "Should the feasibility be low?"

Xiang Shan asked: "What about the time?"

"Immune cell production organization The division is very vigorous and life activities are active, so the transition will be very fast." Yoggmov said: "I haven't done the experiment yet, so I can't give an exact figure. But it will probably be completed within 14 days-seven days is not impossible. "

Xiang Shan hold his head: "This is too fast..."

"And there is another benefit." Yoggmov said: "Immune system life cycle reversal is a Process. In this process, memory cells will gradually eliminate their recorded antigens. Non-specific immune cells will be produced more and more slowly. Their immunity will return to the embryonic stage after a period of time. In the early stage of this reversal phase There is no need to use a sterile ward, or even to be hospitalized."

"Then these friends will find that the dietary allergies that have plagued them for many years have disappeared. But at the same time, the past vaccines are in vain. Now."

"The medicine..."

"It's just a few signaling molecules." Yoggmov is very confident: "After I have completed the basic theoretical research, this is the easiest to find The synthetic medicine is here."

Xiang Shan holds his head in his hands: "God... is the perfect solution?"

He almost wanted to stand up and give Yoggmov a high-five.

However, the memory of being fooled by fiercely just made him instinctively alert.

Xiang Shan said: "Yogg, let me confirm again... This medicine It shouldn't be caused the life cycle of other tissues to reverse? For example... Well, the nerve system? If the nerve system is Reversion to infancy, no, reversion to puberty is enough to terrifying."

"Theoretically, different factors should be used to issue'commands' for different tissue cells. Past experience also illustrates One point. To trigger this function, a single instruction is not enough" Yoggmov thought: "A set of instructions that can act on the whole body...maybe there?"

Xiang Shan said: "That's right. What about aging?"

"It's just that some tissues have returned to the past state at the level of cell function. At the micro level, the telomeres that control cell lifespan have not been replaced, and the traces caused by time still exist. In At a more macro level, the body as a whole will not change. The elderly who receive this therapy will at best become'old people with some cells functioning like fetuses'."
