Chinas early realization of human stem cell space for the first time

China has achieved early hematopoietic production in space environment for the first time in China.

According to CCTV News on Saturday (June 3), with the successful launch of Tianzhou 6, Shenzhou No. 15 multiplier has assisted the six to 15 days of cells in the first six to 15 days of cells.Rail culture experiments, including the first development of human embryonic stem cells under the condition of space conditions.

Lei Xiaohua, a researcher at the Institute of Biomedicine and Technology, Shenzhen Institute of Advanced Technology, Chinese Academy of Sciences, said in an interview that Shenzhou No. 15 astronauts have successfully differentiated a hematopoietic stem cells similar to cobblestone, and this isThe hematopoietic stem cells will be further matured and differentiated to form a hematopoietic stem cell group similar to a grape skewers.Judging from the experimental results, China has successfully achieved the first human stem cells to create blood under space conditions and complete the first experimental goal.

Lei Xiaohua said that in the next stage, the scientific research team needs to conduct a comprehensive detection and analysis of this hematopoietic stem cell group, and to screen the space environment to influence the early hematopoietic division of stem cells by comparing the ground comparison group.Related genes.The scientific research team will continue to use the opportunity of Tianzhou VII or Tianzhou 8 spacecraft to continue the research on the three -dimensional growth research of polyps stem cells in the space environment.

In 2017, the Chinese scientific research team used Tianzhou -1 freight ships to carry out the proliferation and differentiation research of mice embryonic cells.The results show that the space micro -gravity environment provides favorable conditions for the 3D growth and maintenance of mice embryonic cells. Stem cells show a 3D growth method that is better than the ground in space culture and maintains a higher level of poly energy gene expression.Essence

In recent years, foreign scientists have also reported many years of research on the growth and tissue regeneration of stem cells carried out in the space flight mission, such as research on blood stem cells for astronauts.
