As a result of this study, the somatic cells of male mice were successfully transformed into egg cells by using stem cell technology and gene editing technology, and viable eggs were cultivated. After artificial insemination, two male mice successfully gave birth to offspring. These mice look healthy, have a normal life span, and can continue to reproduce as adults. This research can not only provide new ideas for the reproduction of the animal world, but also bring new solutions to the problem of human infertility. For many infertile couples, this technology may become their hope to realize their fertility dreams, which means that men may also have the opportunity to have children.
However, despite the significance of this study, there are still some potential risks and controversies. Problems such as the increase in the number of animals going to the laboratory and genetic defects need to be considered. In addition, the feasibility and safety of this technology need to be further verified before it can be applied to the field of human reproduction.
It is worth mentioning that this research result has also aroused widespread concern and discussion from all walks of life. Some people think that this technology gives men the opportunity to have children, while others question the morality of this technology. In any case, we must seriously consider the advantages and disadvantages brought by the development of science and technology, apply it cautiously, and let science and technology serve mankind, rather than bring negative effects to mankind. In a word, this research achievement is an important breakthrough in the development of science and technology, which brings new ideas and hopes to the fields of animal reproduction and human reproduction. But at the same time, more in-depth research and exploration are needed to ensure the safety and feasibility of this technology. We humans are also animals, but we are different from other animals: we have autonomy and creativity, can think independently, and can do some "useless actions" that are not helpful for survival and reproduction. Almost all the behaviors of other animals are for survival and reproduction.
But sadly, some of us, who are so special, still regard pregnancy and childbirth as things that women must do and as their obligations. Women should have the right to choose whether to have children or not. Although I know it is a matter of course to choose independently, there will always be people who will talk about their choices and even want to make choices for themselves.
Now many young people don't want to have children, not because of the awakening of consciousness, but because it is really difficult for us to protect ourselves. Please solve our survival problem first, and then let us "multiply".
I said a very heavy topic at the beginning, so let's get to the point quickly. The research to be discussed today may really change some status quo.
Insert preface
Let me make it clear in advance to prevent others from saying that I am a title party: scientists produce eggs through male cell culture and cultivate mice with two biological fathers, but the cultivated eggs still need female afterlife.
But don't worry! In fact, the technology of artificial uterus has made great progress, so it is not only possible for men to have children, but also not too far away.
By then, not only will women's right to choose independently be defended; Male and female couples can also * * completely raise offspring from them; It can also be used to treat severe infertility, and this future is really beautiful.
Scientists gave birth to two male mice for the first time.
The main person in charge of this experiment is Professor Lin Keyan of Kyushu University in Japan, who is an internationally renowned pioneer in the field of eggs and sperm. The original intention of his research is to solve serious infertility, such as Turner syndrome. In women with this disease, one of the X chromosomes is missing or partially missing, which can be said to be incurable by conventional means and can only go deep into the cell level.
How to transform skin cells carrying male XY chromosome combination into female XX version of eggs? Firstly, male skin cells are reprogrammed to stem cell-like state to produce so-called induced pluripotent stem cells (iPS), and then the Y chromosome in these cells is discarded, and then the X chromosome is extracted from another stem cell for replacement, so that cells with two X chromosomes will be produced.
It sounds simple, but scientists have gone through a series of carefully designed steps (including genetic engineering).
