"First of all, stem cell cloning organ culture technology. The current internationally accepted research direction is to use mice to conduct experiments and cultivate relevant human organs and tissues through stem cell cloning intervention, such as ears, hearts, etc.
We believe that the practical application of this technology is of little significance, so we abandoned this research direction and went straight to the goal of developing mature artificial organ technology in artificial placenta.
This artificial placenta can also be regarded as an artificial organ incubator. Its main principle is to simulate the growth and living environment of embryos and organs, so that cloned organs can grow from embryos into mature organs.
In this way, as long as this technology is successfully developed, it can be quickly put into the market for commercial use. We can build such a biological organ cultivation factory, or we can distribute this artificial placenta or artificial organ cultivation box to various hospitals, and then distribute it to various hospitals.
The hospital conducts training independently.
In this way, we can greatly provide patients with timely treatment and save more patients' lives. It can also greatly reduce related costs and reduce the burden on patients.
What's more important is that we use stem cell tissue from the patient's body for cloning. Therefore, the cloned organs are essentially the patient's own organs. Therefore, there will be no rejection reaction when the cloned organs are implanted.
, so patients do not need to take a large amount of anti-rejection drugs after surgery.
And because the fit between the organs is relatively strong, the patient’s postoperative recovery will be very optimistic.”
The experts were surprised when they heard Wu Hao's simple introduction. They didn't expect that Wu Hao and the others were so ambitious that they would start directly from the most difficult one.
But think about it, everyone understands what Wu Hao and his team are doing. For them, all projects must have market value. Instead of following the step-by-step process and chasing after a large group of pharmaceutical giants' biological research institutes, it is better to find another way and jump.
development.
This direction may seem too risky, but if it succeeds, the benefits will be huge. The benefits it brings have far exceeded the economic level and have risen to a higher stage. The significance it brings will undoubtedly be revolutionary.
It will have a profound impact on all mankind and the future world. Its status in history may be no less than that of human beings who invented computers and the Internet, or even higher.
After letting everyone discuss for a while, Wu Hao continued: "Bio-3D printing organ technology, as the name suggests, is the use of bio-3D printing technology to print organs.
Everyone knows about 3D printing technology, and this technology has also been used in the medical field. For example, many joint replacement surgeries currently use 3D printing technology to print related replacement joints.
Compared with traditional technology, this artificial joint printed using 3D printing technology is printed by scanning the patient's original joint shape, so it has a higher matching and is more conducive to the patient's recovery.
This bio-3D printing organ technology uses the principles of 3D printing technology to print organ tissues. In theory, this technology not only prints organs, but also prints various limb tissues of the human body. Such as skin, muscles, hands and feet,
Another example is a certain part of the body, etc.”
Hehehehe...
After hearing Wu Hao's words, everyone present laughed knowingly.
Wu Hao then smiled and continued: "The difficulty of this technology is how to use cells to print living organs and tissues.
You know, 3D printing technology is developing very rapidly now, and 3D bioprinting technology is also developing very rapidly. There are already companies using biological 3D printers to print raw meat, and the meat texture is exactly the same as real meat.
However, there is a problem, that is, the raw meat printed by these technologies is dead, not alive. Therefore, these printed raw meat can only be used for eating.
What our bio-3D printing organ technology wants to print is living organ tissue, which in layman’s terms is living meat, not dead meat. We are not using them to make dishes, let alone frying steaks, but to use them to cook steaks.
It is implanted into the patient's body. If it is a dead organ, it will not only fail to save the patient's life, but may even bring danger to the patient.
So how to print living organs and tissues is the core issue we need to overcome."
Having said this, Wu Hao picked up the water glass and took a sip of water, and then under the eager eyes of everyone, he continued: "To overcome this problem, we must start from two aspects.
First of all, we need to prepare the consumables required for this bio-3D printer machine. This kind of consumables cannot be purchased and must be cultivated by ourselves.
Our scientists believe that instead of using allogeneic cells, it is better to extract cells directly from the patient's body, culture them, and then use these cells to print organ tissue.
In this way, the printed tissues and organs will not be rejected after transplantation, which is beneficial to the patient's recovery.
Therefore, cell clone cultivation technology still needs to be used here, how to cultivate consumable cells suitable for use in biological 3D printer equipment from cell clones extracted from patients.
Secondly, what we have to solve is the key to this technology, bio-3D printing equipment.
The principles and technology of 3D printers are actually not complicated, and manufacturing is also very simple. Currently, this technology on the market is very mature.
However, biological 3D printers are a completely new field, not to mention medical-grade biological 3D printers, which also have to print living organs and tissues, which is very difficult.
Moreover, the consumables to be printed are cells that are only a few microns or tens of microns in size. This requires that the entire biological 3D printer must be fine enough so that it can print these tiny cells.
This places higher requirements on the mechanical structure and system control of the printer, and its accuracy can be no less than that of a photolithography machine.
The second is to print each organ and tissue accurately, and the more complex the organ and tissue, the more difficult it is to print. Although these organs and tissues are composed of cells in different arrangements, this involves the arrangement and combination of cells.
, so this requires that the printer system must have a fully detailed understanding of the structure of the organ tissue so that it can print it out perfectly.
Although we humans currently have a very deep understanding of the structure of our own organs and tissues, to be precise about the arrangement and combination of every cell, this will be a very huge systematic project. At present, there is no pharmaceutical giant, medical research institute or even that country.
