摘　　要：目的:探讨白细胞介素6(IL-6)基因转染的骨位基质细胞系QXMSC, IL6对骨髓移植后造血功能的重建作用。方法:将骨髓造血细胞和骨髓基质细胞系一起经尾静脉注射给同系小鼠,建立骨髓移植(BMT)模型。小鼠的造血功能用脾结节(CFU-S)、粒-单系祖细胞(CFU-GM)、红系祖细胞(CFU-E、BFU-E)测定及外周血各项血液学指标来确定。结果:QXMSC_1 IL-6转基因骨髓基质细胞可明显增强BMT小鼠形成的CFU-S、CFU-GM、CFU-E和BFU-E数,促进外周血象的恢复。结论:QXMSC_1 IL-6细胞可明显促进小鼠骨髓移植后早期造血功能重建。Objective:To study the effect of the IL-6 transfected bone marrow stromal cell, QXMSC_1 IL-6, on the hematopoietic reconstitution in bone marrow transplanted mice. Methods: Bone marrow transplan- tation model was established by infusing hematopoietic cells combined with QXMSC_1 IL-6 into syngeneic recipi- ent mice through the tail vein. CFU-S, CFU-GM, CFU-E, BFU-E, and peripheral blood pictures were as- sayed. Results: QXMSC_1 IL-6 could increase the CFU-S, CFU-GM, CFU-E and BFU-E yields in BMT mice, and accelerate the recovery of peripheral blood cells. Conclusion: QXMSC_1 IL-6 can improve the hematopoietic reconstitution in bone marrow transplanted mice.
