摘 要:造血干细胞分化生成巨核细胞是一个十分复杂的过程,包括造血干细胞动员及其向巨核系祖细胞分化,巨核系祖细胞增殖、分化生成未成熟巨核细胞,巨核细胞的成熟和血小板释放等过程。研究发现,造血干细胞动员及其向各系细胞分化的大部分过程都在一种称为“龛”的结构中进行,多种龛内信号分子参与了造血干细胞的动员和分化调控。该文对造血干细胞龛内参与造血干细胞动员和分化生成巨核细胞的几种重要细胞因子及其调控作用进行综述。

Abstract: It is a quite complex process that hematopoietic stem cells differentiate into megakaryocytes, which is composed of the mobilization of hematopoietic stem cell and differentiation into megakaryocyte progenitor cells, the proliferation of megakaryocyte progenitor cell, generation of mature megakaryocytes, megakaryocyte maturation and platelet release etc. It has been found that the mobilization of hematopoietic stem cell and the differentiation into most lineages are in a structure called "niche“.? A variety of signaling molecules involved in the regulation of hematopoietic stem cell mobilization and differentiation. This review is focus on several important cytokines participating in hematopoietic stem cell mobilization and megakaryocytopoiesis and their regulatory role in the niche.
Key words: hematopoietic stem cell; niche; megakaryocytopoiesis; cytokines; regulation
