Hair grows pluripotent stem cells

Spanish scientists have used new methods to replace the skin with hair and successfully cultivated induced pluripotent stem cells. The ELISA kit has greatly improved the cultivation efficiency of such cells. According to a recent report by the Spanish newspaper "National News", there are two kinds of stem cells in nature: embryonic cells that can develop into various human tissues and mature cells that exist in each organ. Last year, scientists invented a third type of stem cells: induced pluripotent stem cells. This kind of cell is obtained by "delaying" the "biological clock" (reprogramming of genetic program) of ordinary skin cells. It has the advantages of the above two stem cells in medical applications, but its cultivation process is very difficult and inefficient. According to reports, scientists at the Barcelona Center for Regenerative Medicine used a new method to obtain induced pluripotent stem cells with a single hair, which increased the efficiency of this cell cultivation process by 100 times, and the proliferation and development of such pluripotent stem cells were diverse Sex is comparable to embryonic cells. In addition, this pluripotent stem cell also has a major advantage of lack of embryonic cells: the genes of induced pluripotent stem cells cultivated from the hair of a certain patient are matched with it. In this way, in the future, scientists may develop stem cells that can treat specific diseases. According to reports, the induced pluripotent stem cells that are currently cultivated cannot be used for the treatment of diseases, and it is necessary to restore the gene configuration to "pluripotency" through multiple virus introduction studies.
