(China's first realization of human stem cell space hematopoiesis)-Human pluripotent stem cells have unlimited proliferation potential and can differentiate into almost all cell types in the human body, it has become an excellent source of cells for regenerative medicine. Lei Xiaohua, a researcher at the Chinese Academy of Sciences, said that the space experiment being carried out by the Chinese space station has achieved the first goal of the space experiment of human pluripotent stem cells-the first time that human stem cells have made hematopoiesis in space.
