脊椎动物造血干细胞(HSC)产生一组分层组织的红细胞、骨髓细胞、淋巴细胞和巨核细胞谱系的祖细胞,并负责血液系统的终生维持。造血分化程序的失调是包括白血病在内的许多病理的根源。随着人们发现许多控制血细胞发育的转录调节因子和信号通路在人类和果蝇之间是保守的,果蝇已成为研究血细胞谱系生成和血细胞稳态机制的良好模型。在这篇综述文章中,我们讨论了果蝇造血的遗传和分子研究如何有助于我们了解造血生态位以及人类造血恶性肿瘤的起源和/或进展。
Vertebrate haematopoietic stem cells (HSCs) give rise to a hierarchically organised set of progenitors for erythroid, myeloid, lymphoid and megakaryocyte lineages, and are responsible for lifelong maintenance of the blood system. Dysregulation of the haematopoietic differentiation programme is at the origin of numerous pathologies, including leukaemias. With the discoveries that many transcriptional regulators and signalling pathways controlling blood cell development are conserved between humans and Drosophila melanogaster, the fruit fly has become a good model for investigating the mechanisms underlying the generation of blood cell lineages and blood cell homeostasis. In this review article, we discuss how genetic and molecular studies of Drosophila haematopoiesis can contribute to our understanding of the haematopoietic niche, as well as of the origin and/or progression of haematopoietic malignancies in humans.
