Self renewal and apoptosis of haemopoietic stem cells (HSC) represent major factors that determine the size of the haemopoietic cell mass. Changes in self renewal above or below the steady state value of 0.5 will result in either bone marrow expansion or aplasia, respectively. Despite the growing body of research that describes the potential role of HSC, there is still very little information on the mechanisms that govern HSC self renewal and apoptosis. Considerable insight into the role of HSC in many diseases has been gained in recent years. In light of their crucial importance, this article reviews recent developments in the understanding of the molecular, biological, and physiological characteristics of haemopoietic stem cells.
造血干细胞(HSC)的自我更新和凋亡是决定造血细胞数量的主要因素。自我更新高于或低于稳态值0.5的变化将分别导致骨髓扩张或发育不全。尽管描述造血干细胞潜在作用的研究越来越多,但关于调控造血干细胞自我更新和凋亡机制的信息仍然很少。近年来,人们对造血干细胞在许多疾病中的作用有了相当深入的了解。鉴于其至关重要性,本文综述了造血干细胞分子、生物学和生理学特征理解方面的最新进展。
