- lymphoid cell lines such as T cells and B cells. These blood cells are maintained and produced throughout the life of an individual by differentiation and maturation from hematopoietic stem cells, which are common sources.
- the hematopoietic stem cell is a cell having both pluripotency that can be differentiated into functional cells such as lymphocytes, erythrocytes, and platelets and the ability to self-proliferate while maintaining such pluripotency (self-replication ability). It is defined as
- hematopoietic stem cells were first directed to two lineages, myeloid and lymphoid, and differentiated into myeloid progenitor cells (mixed colony forming cells, CFU-GEMM) and lymphoid progenitor cells, respectively.
- myeloid progenitor cells are erythroblast burst-forming cells (BFU-E), erythrocyte colony-forming cells (CFU-E), red blood cells, megakaryocyte colony-forming cells (CFU-MEG), platelets, granulocytes, Macrophage colony-forming cells (CFU-GM) pass through monocytes / neutrophils / basophils, eosinophil colony-forming cells (CFU-EO) pass through eosinophils, and lymphocyte progenitor cells are T It is known that it becomes a T cell via a progenitor cell and a B cell via a B progenitor cell.

- G-CSF granulocyte colony-stimulating factor
- hematopoietic stem cells are mobilized from the bone marrow to peripheral blood. Therefore, the mobilized hematopoietic stem cells are concentrated using a blood component separator and then used for transplantation. ing.
- peripheral blood stem cell transplantation requires continuous administration of G-CSF to the donor for 4 to 6 days, and the side effects (blood coagulation, spleen enlargement) associated therewith are concerned, and the burden on the donor is large.
- the efficiency varies depending on the donor, and sufficient hematopoietic stem cells may not be obtained.
- umbilical cord blood has been found to contain hematopoietic stem cells similar to bone marrow, and it has been clarified that it is effective for hematopoietic stem cell transplantation (see Non-Patent Document 6).

Abstract
Description
近年、造血や免疫機能の不全に由来する各種血液疾患、癌、免疫不全症、自己免疫疾患、先天性代謝異常症等多くの難治性疾患の根治的な治療手段として、自己あるいは同種の造血幹細胞移植が行われている。またごく最近では、脳梗塞や心筋梗塞及び閉塞性動脈硬化症等における治療手段として、造血幹細胞を含むCD34陽性細胞移植の有効性が報告されている(非特許文献2、3、4、5参照)。更に、造血幹細胞移植による神経や筋肉の再生という試みも進められている。その例としては、臍帯血由来のCD34陽性細胞をマウス脳梗塞モデルに移植し、血管新生を介して神経を再生したとする報告(非特許文献2)やCD34陽性細胞により筋損傷の修復が可能という報告(非特許文献5、特許文献1)が挙げられる。これらの中でも、骨髄移植は治療実績が多く、標準的な造血幹細胞移植治療法として最も確立されている。しかし骨髄移植のためには、骨髄を提供するドナーと移植を受けるレシピエントのヒト白血球抗原(HLA)の一致率が高くなければならず、ドナーからの骨髄の供給不足が問題になっている。また、ドナーは4日間程度の入院が必要であり、大量に骨髄を採取することに伴う痛み、発熱や出血もあり、ドナーへの負担は大きい。
