- Hematopoietic stem cell is a blood cell that exists mainly in the bone marrow and has self-renewal ability (self-renewal capacity) and pluripotency that can differentiate into all blood cells (multipotency).
- self-renewal means producing cells having the same functions and properties as oneself by cell division. That is, cells produced by self-renewal of hematopoietic stem cells have pluripotency and self-renewal ability to all blood cells.
- Hematopoietic stem cells are classified into short-term hematopoietic stem cells and long-term hematopoietic stem cells according to their ability to maintain hematopoiesis.
- long-term hematopoietic stem cells refer to hematopoietic stem cells that have a longer-lasting self-renewal ability than short-term hematopoietic stem cells, and long-term hematopoietic stem cells have long-term bone marrow remodeling ability (for example, bone marrow even in secondary transplantation). Has the ability to reconstruct).
- short-term hematopoietic stem cells can reconstruct bone marrow in vitro or in primary transplantation, but cannot maintain this ability in secondary transplantation.
- the secondary transplantation means that the bone marrow-derived hematopoietic stem cells reconstructed by the primary transplantation are transplanted into another individual.
- hematopoietic stem cells refer to both short-term hematopoietic stem cells and long-term hematopoietic stem cells.
- hematopoietic stem cells Differentiation of hematopoietic stem cells means that long-term hematopoietic stem cells (long-term HSC: LT-HSC) become short-term hematopoietic stem cells, short-term hematopoietic stem cells become pluripotent hematopoietic progenitor cells, and pluripotent hematopoietic progenitor cells become pluripotent hematopoietic progenitor cells.

- hematopoietic stem cells only long-term hematopoietic stem cells and short-term hematopoietic stem cells have self-renewal ability, and cells downstream of pluripotent hematopoietic progenitor cells differentiate. Although it has cell division ability associated with it, it is said that it does not have self-renewal ability.
- proliferation of hematopoietic stem cells usually means that the number of hematopoietic stem cells is increased by culturing the hematopoietic stem cells in vitro.
- proliferation of hematopoietic stem cells can be achieved by self-renewal of hematopoietic stem cells having the same properties from at least some hematopoietic stem cells.
- Hematopoietic stem cells are known to self-renew in vivo, but no specific factor that induces this self-renewal has been identified, and in vitro induces hematopoietic stem cells to self-renew in the same manner as in vivo. However, it was difficult to grow it. According to the culture method of the present invention, hematopoietic stem cells can be proliferated in vitro while maintaining self-renewal ability and pluripotency.
- Hematopoietic stem cells can be identified using a marker that is expressed, preferably a marker that is specifically expressed in hematopoietic stem cells, and a marker that is not expressed in hematopoietic stem cells (negative marker) as an index.

- Lineage-negative cells Cells that do not express all or part of the cell lineage marker may be referred to as Lineage-negative (Lin-negative or Lin-) cells.
- the mouse Lineage-negative cells may be cells that do not express Ter-119, B220, CD3, CD4, CD8a, Gr-1, CD11b, IL-7R, or the like.
- human hematopoietic stem cells are cells identified by the presence or absence of expression of one or more markers selected from the group consisting of CD34, CD38, Lineage, CD90, CD45RA, CD49f (eg, CD34 positive cells, CD34). Positive and CD38 negative cells, CD34 positive, CD38 negative, CD90 positive and CD45RA negative cells, CD34 positive, CD38 negative cells, CD90 negative and CD45RA negative cells, CD34 positive, CD38 negative, CD90 negative and CD45RA positive cells). ..

- transplanting cultured hematopoietic stem cells into this mouse it is possible to measure the ability of the transplanted cells to engraft in the bone marrow, pluripotency, and bone marrow remodeling ability. Furthermore, by collecting the bone marrow of an immunodeficient mouse that has been transplanted once and transplanting it again (secondary transplantation) into another NOG mouse, it is possible to measure the self-renewal ability and long-term bone marrow remodeling ability of the transplanted cells. is there.
- long-term bone marrow remodeling ability is obtained by transplanting hematopoietic stem cells into immunoprotected NOG mice irradiated with a lethal dose of radiation, and for a long period of time (1 month or more after transplantation, preferably 2 months or more, 3 months or more). It can also be confirmed by the engraftment of the transplanted cells (4 months or more).
- engraftment of the transplanted cells may be confirmed by detecting cells expressing a human marker in NOG mouse blood.
- human CD45 which is a common white blood cell antigen, may be detected by an antibody thereof or the like.
- the proportion of human leukocyte cells (eg, human CD45-positive cells) in the blood at 1 month (preferably 2 months, 3 months, 4 months) after transplantation should be increased as compared with the comparison target. Just do it. That is, when the ratio is maintained or increased with respect to the comparison target, it can be confirmed that the long-term hematopoietic stem cells of the target are maintained or amplified.

Dependent. Therefore, the high or low ratio of human leukocyte cells (eg, human CD45 positive cells) in the blood does not matter, but for example, the ratio is 0.1% or more, 0.5% or more, 1% or more, 5%. It may be 10% or more.
