Abstract

Hematopoiesis is a dynamic process, which generate in the range of 10(9) cells/kg each day of erythroid and myeloid cells respectively. In vitro assays that were developed 20 years ago, have been used to define factors that can stimulate growth and differentiation of bone marrow (BM) derived progenitor cells. These growth factors for hematopoiesis were termed Colony Stimulating Factors (CSFs) since the assay system was to induce colonies. With the application of molecular biologic approaches, the genes encoding for these CSFs have been localized and cloned. Production of CSFs and other soluble signal substances (cytokines) as pure proteins have led to important insights into how hematopoiesis is regulated by a complex network made up by interactions between cells and cytokines. The availability of CSFs in clinically useful amounts has also led to clinical trials with new strategies for treating hematopoietic dysfunctions, congenital or acquired. Because others have recently reviewed clinical applications or basic science studies on the colony stimulating factors, we will summarize the two with focus on common features between the different CSFs.

集落刺激因子。
造血是一个动态过程,红细胞和髓细胞每天分别产生10(9)个/kg。20年前开发的体外试验已被用于确定能够刺激骨髓(BM)衍生祖细胞生长和分化的因素。这些造血生长因子被称为集落刺激因子(csf),因为该检测系统是诱导集落。利用分子生物学的方法,已经定位并克隆出了这些csf的编码基因。造血干细胞和其他可溶性信号物质(细胞因子)作为纯蛋白质的产生,使我们对造血是如何由细胞和细胞因子相互作用组成的复杂网络调节的有了重要的认识。临床上有用的csf的可用性也导致了治疗先天性或后天性造血功能障碍的新策略的临床试验。由于最近有人回顾了集落刺激因子的临床应用或基础科学研究,我们将对两者进行总结,重点介绍不同csf之间的共同特征。
