造血干细胞(HSCs)在脊椎动物的整个生命过程中支持造血和免疫系统的维持,是骨髓移植的治疗组成部分。了解造血干细胞的天然特性,以发现可能有助于改进体外定向分化方案的关键信号,一直是生物医学的一个长期目标。目前还不可能在体外确定真正的造血干细胞,这表明关键信号仍然未知。我们推测,这种信号可能是通过周围的“小生境”细胞呈现的,但还没有定义这样的细胞。在这里,我们在斑马鱼身上证明,在明确的造血程序开始之前,躯干神经脊(NC)与背主动脉(DA)中的HSC前体在物理上相关。阻止NC与DA的关联会导致HSC的丢失。我们的结果将NC定义为HSC规范利基的关键细胞组件,可以用来识别未知的HSC规范信号。
Haematopoietic stem cells (HSCs) support maintenance of the haematopoietic and immune systems throughout the life of vertebrates, and are the therapeutic component of bone marrow transplants. Understanding native specification of HSCs, to uncover key signals that might help improve in vitro directed differentiation protocols, has been a longstanding biomedical goal. The current impossibility of specifying true HSCs in vitro suggests that key signals remain unknown. We speculated that such signals might be presented by surrounding “niche” cells, but no such cells have been defined. Here we demonstrate in zebrafish, that trunk neural crest (NC) physically associate with HSC precursors in the dorsal aorta (DA) just prior to initiation of the definitive haematopoietic programme. Preventing association of the NC with the DA leads to loss of HSCs. Our results define NC as key cellular components of the HSC specification niche that can be profiled to identify unknown HSC specification signals.
