Military Technology

Although everyone really wanted to stay for a while, let's take a look at the biological 3D printer in front of the glass. However, under the guidance of Wu Hao, everyone can only regret to leave and go to the place to visit below.

Under the guidance of Wu Hao, everyone walked through a glass corridor and entered a new laboratory at the corner.

Entering here, everyone's eyes suddenly lit up.

Because the space here is very large, it seems to be in a hospital. The related arrangements and facilities are the same as those of the hospital, as well as special operating rooms, wards and so on.

Xiao Wu, where is this? Seeing this scene, Director Qi Feng asked him involuntarily.

Wu Hao introduced with a smile: "This is a special clinical hospital we set up to conduct clinical trial research on our related technologies."

Hearing Wu Hao's words, everyone couldn't help but wonder, could it be that Wu Hao and the others are still secretly conducting clinical trials here, this is illegal, how can this kid be so bold.

Looking at the surprised and confused expressions of everyone, Wu Hao said with a smile: "But what we are testing here is not patients, but some experimental animals."

After speaking, Wu Hao made a gesture of invitation: "Everyone, come with me."

Immediately, everyone entered a ward with a large space, and the most interesting thing was some small spaces separated by acrylic transparent panels, where various animals lived.

Wu Hao brought everyone to the front of Xiaozhu, and through the transparent acrylic board, Wu Hao smiled at everyone and introduced: "Everyone, please see, this is a piglet that we have completed autologous cell cloning and 3D bioprinted skin transplantation. The lighter part of the hair on its back is the skin tissue that we 3D printed.

Judging from the current testing situation, the recovery of this part of the skin is good, there is no problem, and the health of the piglet is also very good. "

Having said that, Wu Hao gestured to the experimental staff next to him. I saw the experimenter nodded, and immediately took out the piglet inside. The little pig is very strong, and it took the experimenter a lot of work to show the little pig in front of them.

Seeing this little pig, everyone gathered to watch it. As for Wu Hao, he also smiled and pushed aside, giving up the space to everyone.

Xu Shenghua, Zhang Qinghong, and the others wore medical rubber gloves, and then carefully removed the light hair on the piglet's body, and carefully checked the relevant situation.

As for the little pig, it was a little uncomfortable in the arms of the experimenter, but under the comfort of the experimenter, he didn't struggle too much and seemed very good.

The wound healed well, the scar was very shallow, and the grafted skin survived very well, with the pig hair growing vigorously. After Professor Xu Shenghua checked it, he nodded and praised with a smile.

Zhang Qinghong also nodded, but he immediately turned his head and asked Wu Hao: "Mr. Wu, I have noticed that there is a significant color difference between this newly injected skin and the pig's own skin. I would like to ask, this kind of Is the chromatic aberration the difference between the biological 3D printed skin and the original skin, or the difference between the old and new skin?

How to solve such a problem in the later stage? Is there a solution? This is very important for some facial skin repair and transplantation patients. It is impossible to make their face darker and shallower, and become a flowery face. What is the difference between this and no transplant repair? . "

Hearing Zhang Qinghong's question, Wu Hao replied with a smile: "It's a question of old and new skin. There is no difference between the 3D bioprinted skin and the piglet's skin tissue itself. It's just that the growth time is different. It's like a newborn baby's skin. Like adult skin, the skin needs an adaptation process. Generally speaking, it may take half a year to a year to basically return to the same level. Of course, if some auxiliary methods are used, this process will be accelerated.”

Speaking of this, Wu Hao changed his tone and said with a smile: "However, I don't think anyone would do this in general. For many people, it's too late to cherish you when you suddenly give you a young face, how could you do it on purpose? 'Old' yet.

I thought that what everyone asked about should not be how to make these newly implanted skins old, but how to replace the original skins with new ones. "

hehehehe...

Hearing Wu Hao's words, everyone present laughed. Indeed, that is the case, and they have encountered such a thing many times. The male patient is okay to say, the female patient has more demands.

Such skin will not be particularly intolerant of aging, or the lifespan is too short. A young doctor in the crowd asked.

Hearing the doctor's words, Wu Hao smiled and shook his head: "No, these skins are cultivated and printed using the experimental body's own cell clones, so its sale is actually the same as the lifespan of pig skins, no There will be a problem that the lifespan is too short and not resistant to aging.”

Hearing Wu Hei's explanation, another expert next to him immediately asked the question: "Since this is the case, will the two types of skin have the same degree of aging in the future, and the problem of differentiation will appear."

Jiang is still old and hot, and as soon as he asks a question, he grasps the crux of the problem.

Wu Hao praised in his heart, and then nodded with a smile: "There is such a possibility, Xiaozhu is okay to say, after all, its age is too young, so the time difference between its own skin and biological 3D printed skin is not much, so no There is impact.

But for people, it's different, especially for some people over the age of 20 or 30, there may be such problems in the future when they age~www.readwn.com~ After all, the original skin of these patients is different from the The difference between the newly printed skin tissue of the biological 3D printer may be decades or decades. You may not see it when you are young, but when you are in your 40s or 50s, you can see obvious differences.

At present, there is no solution to this problem, and there is basically no solution. Unless we use the relevant gene editing control technology to make the newly printed skin of the biological 3D printer consistent with the original skin of the patient. "

After saying this, Wu Hao glanced at everyone, and immediately changed his tone with a smile: "Actually, you don't need to worry too much about this issue, because compared to decades later, we can help patients at the most important age in their lives. Getting back to normal looks is so important to them.

As for the future, maybe the related problems can be solved. Even if it can't be solved, after the age of 40 or 50, everyone's pursuit of skin and appearance is not as concerned as they were when they were young.

In addition, from the perspective of biological science, there are many factors that affect skin aging, not necessarily the skin itself. So after a few decades, even if there is a difference between the old and new skin, it will be very small, and it can even be said that there is no gap. "
