Migration of hematopoietic stem cells (HSCs) is essential during embryonic development and throughout adult life. During embryogenesis, trafficking of HSCs is responsible for the sequential colonization of different hematopoietic organs by blood-producing cells. In adulthood, circulation of HSCs maintains homeostasis of the hematopoietic system and participates in innate immune responses. HSC trafficking is also crucial in clinical settings such as bone marrow (BM) and stem cell transplantation. This review provides an overview of the molecular and cellular signals that control and fine-tune trafficking of HSCs and hematopoietic progenitor cells in embryogenesis and during postnatal life. We also discuss the potential clinical utility of therapeutic approaches to modulate HSC trafficking in patients.
造血干细胞(HSCs)的迁移在胚胎发育和整个成年期都是至关重要的。在胚胎发生过程中,HSCs 的运输负责血液生成细胞依次定殖不同的造血器官。在成年期,HSCs 的循环维持造血系统的内稳态,并参与先天免疫反应。HSC 运输在骨髓(BM)和干细胞移植等临床环境中也至关重要。本综述概述了控制和微调 HSCs 和造血祖细胞在胚胎发生和出生后生命中运输的分子和细胞信号。我们还讨论了在患者中调节 HSC 运输的治疗方法的潜在临床应用。
