红细胞生成是一个复杂的过程,从造血干细胞开始,导致每天产生2000亿个红细胞(rbc)。去核是哺乳动物红细胞生成终末成熟过程中一个非常复杂且具有限制性的步骤,包括从正色红母细胞中排出细胞核,从而形成网状红细胞。动态去核过程涉及许多因素,从细胞骨架蛋白到转录因子到mirna。缺乏最佳的终末红细胞成熟和去核是体外最佳红细胞生成的障碍。过去二十年的重大努力揭示了一些支配去核过程的机制。这篇综述将详细讨论与去核有关的机制,并讨论这一迷人过程的未来前景。
Erythropoiesis is an intricate process starting in hematopoietic stem cells and leading to the daily production of 200 billion red blood cells (RBCs). Enucleation is a greatly complex and rate-limiting step during terminal maturation of mammalian RBC production involving the expulsion of the nucleus from the orthochromatic erythroblasts that result in the formation of reticulocytes. The dynamic enucleation process involves many factors ranging from cytoskeletal proteins to transcription factors to miRNAs. Lack of optimum terminal erythroid maturation and enucleation has been an impediment to optimum RBC production ex vivo. Major efforts in the past two decades have exposed some of the mechanisms that govern the enucleation process. This review will focus in detail on mechanisms implicated in enucleation and discuss the future perspectives of this fascinating process.
