Want to live to be 120? Stem cell technology can help you dream

should I pay attention to when I receive stem cell treatment? Is the DNA and recipient of the transplanted person's blood consistent after a bone marrow transplant of hematopoietic stem cells? Can interstate stem cells be mass produced? Will an allogeneic injection of stem cells produce an exclusive reaction? What are the possibilities for the research and application of stem cells in orthopaedics? Recently, in the 47th Science Lecture on Understanding the Future on the theme of "The Imagination and Reality of Returning To The Old Child: The Future of Stem Cells and Regenerative Medicine", participants threw out these public concerns to the speakers.
, the average human life expectancy was only 35 years. According to the latest data released by the National Health And Health Commission in July this year, the average life expectancy of Chinese residents in 2018 reached 77 years, with about 249 million elderly people aged 60 and over, accounting for 17.9% of the total population, but more than 180 million elderly people have chronic diseases, the proportion of people suffering from one or more chronic diseases as high as 75%.
people live longer while improving the quality of life? In recent years, stem cells and regenerative medicine have become a hot topic in the field of health, and these new technologies can not only treat diseases, but also be used to fight aging.predicts that the future impact of stem cells on society, like the ad emerging of smartphones, will revolutionized people's lives.
" stem cells can be divided into models, tools and drugs. In practical application, from in-body culture to preclinical research relying on animal experiments, to clinical application, it is actually a long process. In stem cell research and development, scientific layout, industrial planning, management and publicity still need to be strengthened. "At the lecture, Li Wei, a researcher at the Institute of Zoology of the Chinese Academy of Sciences and deputy director of the National Key Laboratory of Stem Cell and Reproductive Biology, said.
stem cell anti-aging research, attracting the attention of the world's top medical researchers. Some developed countries have made rapid progress, not only in the treatment of diseases, but also in anti-aging has made great achievements.
2006, Nobel Laureate and Japanese scientist Tsahmi Yamano found that four genes were able to reprogram cells to restore them to a young and even embryonic stem cell state. In experiments, Yamano has proven that the use of this technique can improve the vitality of human skin cells in petri dishes. In addition, they experimented with a mice with early aging disease, which resulted in the elimination of the characteristics of premature aging and longer life expectancy.
at the Salk Institute in California used "cell reprogramming" to make human skin cells in petri dishes younger, both in the table and in them. They also experimented with mice with premature aging, which eventually eliminated aging characteristics and extended their lifespan by 30 percent.
, compared with the United States and Japan, China's stem cell research started relatively late. At present, stem cells are new in the domestic medical field, but there are still some technologies that have entered a mature stage. Under current medical conditions, patients can only rely on life-long medication to prolong their lives in the face of cardiovascular diseases, chronic respiratory diseases, diabetes and cancer, which may be cured as stem cell technology continues to evolve in recent years."80, or 90? A few years ago, an old life star in Xinjiang lived to 128 years old - a person can live up to 120 years, so why do very few people live to this age? Because our organs will age and wear, and regenerative medicine will solve this problem. Dai Jianwu, a researcher at the Institute of Genetics and Developmental Biology of the Chinese Academy of Sciences, told reporters.
is regenerative medicine? Regenerative medicine uses biological materials and some inducing factors to repair and reconstruct tissues or organs using cells in our bodies, Dai explains. Of course, rebuilding tissue organs is not as easy as pinching faces.
more than a decade of efforts, the team of scientists at the Institute for Genetic Development has successfully developed a functional biomass based on collagen that, in combination with human stem cells or regenerative factors, can lead to the regeneration of different tissues.
" so in the near future, blind people can see the light again, people in wheelchairs can stand up and walk like us. Regenerative medicine can reconstruct a bladder, a liver, or even a heart. In the future, people who need organ transplants won't have to wait long, and most of us should be able to live to 120 years of age - that's the dream of regenerative medicine. Dai Jianwu said.
regenerative medicine is a new medical technology that has only emerged in the last 20 years. "Like developed countries such as the United States and Japan, China has invested considerable research and development. The research of regenerative medicine in the field of nervous system and reproductive system in China is now at the forefront of the world. Whoever does it fast and who does it well occupies the commanding heights. Dai Jianwu said.
, the stem cell research team at
Animal Research Institute has initiated and completed several clinical studies of stem cell therapy in patients with Parkinson's disease on the basis of 12 years of basic and preclinical research.
" is a great encouragement to the steady development of regenerative medicine. Li Wei said that although stem cell research and development still needs a process, it is expected that within five to 10 years, the State Food and Drug Administration approved the sale of stem cell drugs.
