Latest website: Simply put, there are two difficulties in bio-3D printing technology. One is how to accurately use human cells to print active organs.

The second problem is because the biggest problem of stacked bio-3D printing technology or the biggest problem of this type of 3D printer is that the printing time is too long. How to ensure the survival of the printed organs and cells during the printing process.

It should be known that the survival time of organs in vitro is very short, and different organs are different, so the in vitro survival time is not the same. Say a day and a half. And some, even after pretreatment, will survive in vitro for a short time, only a few hours. If it is not pre-processed, it is likely that it will only be used for twenty or thirty minutes, or even a few minutes.

Therefore, whether it is for doctors or patients, it is better to place the organs in vitro as short as possible, the shorter the time, the better the transplant effect, and the better the organ function is maintained.

In the long process of printing, how to ensure the survival of this organ is also an urgent problem that needs to be solved.

It is really not easy to solve this problem. Currently, there are mainly two solutions.

One is to speed up the printing speed as much as possible, so that the organ can be successfully printed in the shortest time. In this way, the vitality of the 3D bioprinted organ can be greatly maintained, thereby ensuring the success rate of the transplant operation.

The other is to use some technologies to ensure the vitality of the 3D bioprinted organ during the printing process, such as low temperature beating environment, perfusion soaking preservation solution, etc.

In general, however, both approaches work together. But even so, it still can't be extended for much time.

Therefore, it is necessary to have more advanced biological preservation technology to maintain the firepower of these printed organs during the printing process.

The current research direction of the biological 3D printing technology team is to install a biological organ printing chamber under the biological 3D printer. This printing chamber can be regarded as a biological organ printing chamber or an artificial organ hotbed, or an organ placenta. .

The viability of the organ is maintained during the printing process, so that the organ can remain viable even after a long period of bio-3D printing.

As for this 13-square-centimeter bio-printed skin tissue, it is a technical limit of their current technology. Even if you want to break through, you won't make much progress.

Unless the artificial organ hotbed technology can be developed successfully, it will be possible to print larger sizes of skin tissue and lay the foundation for the printing of other organs.

Of course, this technology can be used if it can be used. One biological 3D printer can print 13 square centimeters, then ten biological 3D printers can print 130 square centimeters, which adds up to a large piece of skin tissue, which is used to treat some patients with severe skin damage , is also very useful.

It's just that due to the limitations of current technology, the cost of this kind of bio-3D printed skin tissue is very expensive, and I am afraid that it is difficult for ordinary patients to afford it.

Since it didn't land so quickly, why should it be released in advance? This is not in line with our usual tradition. Zou Xiaodong asked a little puzzled.

Hearing his words, Wu Hao and Zhang Jun laughed. Wu Hao looked at him and said, "This is also a major achievement, is it normal to release it to the society?

This technology is relatively cutting-edge and avant-garde, and it may be difficult for the public to accept it for a while, so the early release is also a process for everyone to adapt and accept.

These two, isn't this the New Year? It can be considered as a gift for everyone, especially for those patients who have suffered disfigurement and skin damage, so that they can have hope. I think this is the best gift for them. gift. "

Hearing his words, the three listening nodded in agreement. Indeed, for such people, this is definitely the best New Year's gift for them.

Wu Hao continued: "The third thing is, we have noticed that other medical technology companies also seem to have this technology. In order to avoid them preempting and malicious marketing, it will bring some influence and influence to our future release of this technology. problem, so we're going to release it early.

In this way, even if other medical technology companies want to release, they have to be careful not to have Zhu Yu in front. Besides, even if they are released, the public will take our technology as the standard to measure their released technology. "

"In the end, it's naturally to raise some research fees.

Although we said that our investment in this project is relatively sufficient, but who would dislike having more money, so this release will see if we can raise some public welfare research funds from other non-profit organizations and the rich. Even if it is tens of millions, we are not too small anyway. "

Hehehe, Zhang Jun and the three of them all laughed when they heard Wu Hao's words. Indeed, the more sufficient scientific research funding, the better, after all, who would dislike more money.

I believe that after this technology is released, it will definitely arouse the interest of many people.

Actually, I have another idea about this technology. Zhang Jun smiled at the three and said, "In our country and internationally, there were not many people in special positions who were injured on the job, such as firefighters, police officers, soldiers, and those who fought for justice and so on.

So when our technology is put into clinical application, can we recruit a few representative volunteers from this group?

On the one hand, we can also conduct clinical trials of this technology in these people. Second, during the clinical trial, we can also do charity work~www.readwn.com~ to help these people restore their normal appearance and skin.

These three can also take this opportunity to publicize this technology and expand its domestic and international influence. "

By analogy, not bad! Wu Hao praised Dao Tou with a smile. He was able to have such an idea during this period of time. He has to say that Zhang Jun is really a business genius.

I agree that even philanthropy alone is worth doing, these people are really amazing. Yang Fan nodded in agreement.

Zou Xiaodong agreed, but he also expressed his concerns: "Yes, but we have to wait until the technology is safe and reliable enough, until the third phase of clinical trials, at least until the second phase of clinical trials, to minimize the risk. .

Otherwise, if there is an unexpected problem, the impact can only be negative, and it will continue to be amplified because of this special group. In that case, we will lose more than our gains.

Therefore, this is a double-edged sword, and it must be used with great care. If you use it well, it is a weapon for killing people. If you use it badly, it becomes a murder weapon. "
