Create a new life without sperm and eggs?What should Tsinghua develop "magic water"?

The starting point of life comes from a group of "small tadpoles" adventure? This may become a "past." A new research result of Tsinghua University can bypass sperm eggs to create new life!

Tsinghua University Ding Sheng team has experienced 6 years of research, creating a "magic water" - "TAW cocktail". This kind of water can be re -changed from the cells of rats to a "all -around stem cell". This omnidirectional stem cells have "the potential of infinite differentiation" -that is, these cells can constantly split and copy, and eventually evolve into complete organs and tissues, and can even create an independent life.

Sun Wukong's "unique" may become a reality

Make a metaphor for everyone -pulling a slightest hair in the Journey to the West, you can change tens of thousands of monkeys and monkeys. If you must use modern science to explain, then these cents must contain a large amount of omnidirectional stem cells. The origin of life is fertilized eggs, and fertilized eggs are a type of all -around stem cells. If you put aside the fertilization process, this all -around stem cells have the ability to evolve into any tissue and organs.

The continued differentiation of Almighty Stem cells will lose a potential of evolution and become a variety of stem cells. For example, the bone marrow can make hematopoietic stem cells, which can be differentiated into at least 12 types of blood cells, but it cannot form a complete life individual.

Reconstruction of multi -functional hematopoietic stem cells will become a capable stem cell, and eventually forms tissue and organs in our body, and these cells will also lose the ability to differentiate.

In other words, as long as we have enough all -around stem cells, we can create a new life.

Isn't it "clone"?

Some netizens will have questions. Isn't Sun Wukong creating monkeys and monkeys, isn't it "clone" himself? This is also a misunderstanding that many people have. In fact, Sun Wukong's avatar and cloned technology are essentially different.

The cloning technology requires reproductive cells -the combination of sperm and eggs to form fertilized eggs, and the fertilized eggs are implanted into the mother body into embryos, and eventually produce individuals. We can see that in addition to sexual behavior, cloning creatures have experienced the process of all life. Therefore, cloned is also called "asexual breeding".

And through all -around stem cells, not only skipping the fertilization process, but not even sperm and eggs at all, and even embryos can be bred in vitro.

Not only that, unlike cloning technology, the topic of Ding Sheng's research through "TAW cocktail" can realize the reversal differentiation of stem cells and create a completely different individual through gene resection technology.

But what is the significance of this technology?

Save a race

To make a more intuitive assumption, if there is an endangered tiger in the world, there is only one left in the world, and this tiger is still a male tiger. In the perspective of traditional biology, this tiger is destined to be extinct.

Even if a certain number of genes are kept in the gene library, many problems will be encountered:

1. No maternal breeding life;

2. Insufficient gene diversity affects the quality of population.

However, with the genetic re -programming technology and stem cell reversal differentiation technology, this species has the possibility of saving. Through the genetic reversal technology to extract the all -around stem cells of this male tiger, and then through genetic reassembling technology, it cultivates a new individual with a traditional maternity definition and has no blood relationship with this male tiger. In theory, this technology is completely possible in the future.

Because of this technology has great innovation, the research results of Ding Sheng's team have appeared in the "Nature" magazine, and at the same time, the scientific community has become the achievement of the Nobel Prize.

Last words

However, we cannot be blind and objective. Science and technology are a double -edged sword. This technology will bring huge challenges to social ethics. If there is no way to solve these problems, this technology may not be able to apply in actual life for the time being. After all, the creatures created have no blood relationship with anyone. What should we think of it? An independent individual? Or is it a "product" made from science and technology? More importantly, if this technology is used by bad guys, the consequences will be unimaginable. (Huo Hao)
