Shanghai Qingyuan Li Qingfeng: Stem cell "myth" is not credible

Stem cell research is a key development area in the medical frontier in recent years. Following the upsurge of stem cell research, many anti-aging related to stem cells are filled with various businesses and media, giving people endless imagination. However, in these beautiful "myth" stories, illusion is often more than true.

Studies have reported that stem cells are a class of cells with multi-directional differentiation potential, with the potential to differentiate and regenerate various tissues and organs, just as trunks can continuously grow new leaves. Whether it is heart, liver, spleen, lung, kidney, nerve or blood, it can theoretically be differentiated from stem cells. Stem cells have a large family, in which embryonic stem cells have the ability to differentiate into various cell tissues; adult stem cells can only differentiate into specific tissue cells, such as adipose stem cells can differentiate into fat, bone and cartilage, and neural stem cells can generate nerves. cell. In other words, not every stem cell is “universal”.

The strong differentiation ability of stem cells makes scientists have high expectations. It is envisaged to use the various organ tissues produced by stem cell culture to replace the organs that have been aging or lose function to prolong human life. Through stem cell injection, various cells and tissues are renewed in the body, so that people's body functions are "rejuvenated." The reason why human tumors can proliferate continuously is closely related to cancer stem cells. So if you kill cancer stem cells, can you cure cancer?

Based on the above, there are many illegal medical institutions on the market, which are packaged and marketed by means of stem cell health and stem cell anti-aging concepts. What people need to understand is that there is no medicine in the world that can make people younger. Some people feel good after receiving stem cell injection care in a so-called medical institution. In fact, it is often not stem cells, but hormones or stimulants. At present, there are more than 6,000 clinical trials of stem cells in the world, and only 9 to 11 diseases are approved for treatment. The main reason is that it is still unclear what diseases can be treated by stem cells. At the same time, there are very many stem cells injected into the body. Big carcinogenic risk.
