　　Recently, in a research report published in the international journal Cell Reports, scientists from the Spanish Genome Regulatory Center and Columbia University have identified a special kind that is essential for the expansion of scarce and life-saving blood stem cells. protein. Relevant research may help scientists develop a variety of new methods to multiply a large number of these stem cells in the human body and outside of the body. At present, these stem cells are one of the biggest limitations that scientists use in a variety of medical procedures, including therapies for the treatment of blood cancers. To inherited blood diseases that require bone marrow transplantation.

　　Hematopoietic stem cells (HSCs, Hematopoietic stem cells) are responsible for the continuous renewal of blood. They generate billions of new cells every day. HSCs have unlimited potential. They can renew themselves throughout the life cycle of the organism and produce A type of blood cell, including cells that make up our body's immune system. HSCs also have great potential in the treatment of a variety of refractory cancers, autoimmune diseases and hereditary blood disorders. However, only 1 out of 2500 bone marrow cells are hematopoietic stem cells. This scarcity may greatly limit The scope of use of hematopoietic stem cells in medical procedures.
