The embryonic dragon within the egg had taken shape. According to Xing Bukui's assessment, it would break free in a few more days.
At this moment, the young dragon was still connected to the unabsorbed egg fluid by an umbilical cord.
A silver needle was inserted into the umbilical cord. The groove on the needle extracted stem cells after being withdrawn.
This was followed by the process of cultivating the stem cells.
He needed to select the highest quality cells from countless stem cells and extract the desired gene fragments.
Concurrently, Xi Tong was also busy, cultivating embryos using stem cells from Xue Rengui.
Stem cells are a type of cell with the ability of infinite or eternal self-renewal, capable of producing at least one type of highly differentiated daughter cell.
Classified by their developmental stage, stem cells can be divided into embryonic stem cells and adult stem cells.
In adults, embryonic stem cells disappear and develop into adult stem cells.
Adult stem cells refer to undifferentiated cells found within a differentiated tissue, capable of self-renewal and specializing into the cells that constitute that tissue type.
Adult stem cells are present in various tissues and organs of the body.
Discovered adult stem cells mainly include: hematopoietic stem cells, mesenchymal stem cells, neural stem cells, hepatic stem cells, muscle satellite cells, epidermal stem cells, intestinal epithelial stem cells, retinal stem cells, pancreatic stem cells, and so on.
Xi Tong's task was to use these stem cells to cultivate two new arms!
This was not the first time she had done something like this. When she was shaping the body for another system, she had prior experience.
However, back then, she was cultivating a complete embryo.
This time, it was an embryo that would only develop into arms!
By the time she had cultivated the embryo, Xing Bukui had also completed the extraction of gene fragments.
It was more than half a month later when the gene fragments were incorporated into the embryo.
When Fang Er arrived at the laboratory again, the first thing he saw was the V-shaped tissue submerged in a hibernation chamber, enveloped by a large amount of nutrient solution.
This was the product cultivated over the past half month.
It had no head, nor any other body parts!
It was merely two arms connected at the root. At the ends of the arms, the rudiments of hands had already formed, but the entire structure was less than three centimeters in size.
Xue Rengui, following behind him, looked at the hibernation chamber, utterly bewildered.
"My Lord, are these my future arms?"
Fang Er smiled and nodded, "That's right. Once they're cultivated to a suitable size, they can be transplanted onto you."
Xing Bukui had been guarding the laboratory from the very beginning and had never left. Pointing to the two connected arms, he said with pride.
"At most, half a month!"
"After half a month, the transplant surgery can be performed!"
This plan, up to this point, was successful.
With such experience, he could confidently say that from now on, no one would have to worry about localized problems in their bodies.
Wherever it's broken, it can be replaced, and it will be even more suitable than the original!
Everyone waited patiently. During this time, Xue Rengui drank three large bowls of medicinal soup daily, adjusting his physical condition to the optimal state to prevent any issues during the transplant due to his body.
Those two arms were also developing at an astonishing speed.
Half a month later, a surgical table appeared in the laboratory.
Xue Rengui lay on it, his upper body bare.
Hua Tuo and Sun Simiao personally performed the transplant surgery, with Zhang Zhongjing, Li Shizhen, and others standing by, ready to respond to any unforeseen circumstances.
Dean Zhang and his team from the main world were recording the entire process with cameras. Such a medical case, if brought back, would shock everyone!
An expert whispered excitedly into Dean Zhang's ear.
"Dean, do you think this medical case can win a Nobel Prize?"
Dean Zhang turned back and glared at him displeasedly, "Watch and learn properly!"
"Compared to this medical case, what is a Nobel Prize?"
"Have you considered how many disabled people there are in the world?"
"If this medical case can be successful, it means they can all stand up again, see the light again, and return to a normal life!"
"This time, it's just arms, but next time, we can cultivate eyeballs, lower limbs, or even heads!"
"In a certain sense, such a medical case can ensure that everyone lives out their natural lifespan!"
"Even transplanting a person's brain into a newly cultivated body can achieve human immortality!"
"This will be a medical case that ushers in a new era!"
"This is something that benefits all of humanity, how can it be measured by mere fame and fortune?"
These words stunned the several experts and scholars beside him.
"It can even be like this?"
"Upon closer reflection, it really seems to be the case!"
"As expected, the dean is the dean. Why didn't I think of this?"
"Yes, such a simple principle as drawing inferences from one instance, I actually didn't think of it!"
"Live and learn, this saying is truly flawless. The dean's words give me a feeling of sudden enlightenment!"
".........."
A group of people were murmuring quietly, and Fang Er, standing nearby, heard everything clearly.
He was also stunned, as Dean Zhang's words were quite surprising to him.
He had proposed this plan merely to get two new, most suitable arms for Xue Rengui.
He had never expected it to have such significance!
Holy cow!
Simply astonished, my friends........
Did I accidentally........
Change the era?
A sense of accomplishment surged into his heart. He curved his lips slightly and turned to look at the operating table.
At this moment, Xue Rengui was no longer just a patient receiving arm transplants; he was a hero sacrificing for medical science!
A great hero!
Of course, Xue Rengui was unaware of all this.
Right now, he lay there, sleeping more soundly than a pig.........
