摘要为了阐明原发性血小板增多症(ET)患者中巨核细胞数量增加的机制,我们研究了ET和其他骨髓增生性疾病中的体外巨核细胞生成,使用含甲基纤维素的血浆或血清以及植物血凝素(PHA)刺激的白细胞条件培养基(PHA-LCM)中的巨核细胞集落试验。肝素化或柠檬酸化血浆和柠檬酸化血清(在柠檬酸化血浆形成凝块后收获)充分支持巨核细胞集落形成。全血清对巨核细胞集落生长有抑制作用。加入血小板释放物和部分纯化的血小板衍生生长因子(PDGF)导致巨核细胞集落数量减少。这些结果表明,血清中的血小板衍生因子对巨核细胞集落形成具有抑制作用。
Summary. TO clarify the mechanism of increased numbers of megakaryocytes in patients with essential thrombocythaemia (ET), we studied in vitro megakaryocytopoiesis in ET and other myeloproliferative disorders, using a megakaryocyte colony assay in methylcellulose containing plasma or serum and medium conditioned by phytohaemagglutinin (PHA) stimulated leucocytes (PHA‐LCM). Megakaryocytic colony formation was supported well by heparinized or citrated plasma and citrated serum which was harvested after clot formation of citrated plasma. Whole serum was inhibitory for megakaryocytic colony growth. The addition of platelet releasates and partially purified platelet derived growth factor (PDGF) resulted in a decrease in the number of megakaryocytic colonies. These findings suggested that platelet‐derived factor(s) in serum was inhibitory to megakaryocytic colony formation.
