近十余年来,有关造血间质微环境的研究颇为活跃。不少报导说明:造血间质微环境在造血干细胞及其后代的定居定向、增殖分化、成熟乃至释放的全过程中起着诱导,支持和调控作用。造血微环境业已成为实验血液学和临床血液学中的专门术语。这一术语或泛指造血器官内除造血实质细胞以外所有参与调控造血的间质成分;或特指造血组织中一些具有特殊结构和功能的微细区域——龛(niche)。 The past ten years, the study of hematopoietic microenvironment quite active. Many reports show that the hematopoietic microenvironment plays an inducing, supporting and regulating role in the process of colonization, differentiation, maturation and even release of hematopoietic stem cells and their offspring. The hematopoietic microenvironment has become a specialized term in experimental hematology and clinical hematology. The term or broadly refers to all blood-forming interstitial components involved in the regulation of hematopoiesis in hematopoietic organs other than hematopoietic parenchymal cells; or, in particular, some niche in hematopoietic tissue that has a special structure and function.
