本实验观察了成纤维细胞介导的G-CSF基因疗法对大剂量化疗后造血功能损伤小鼠的恢复作用。结果发现:接受G-CSF基因治疗的实验小鼠外周血白细胞尤其是中性粒细胞降低程度明显减弱,恢复速度明显加快;并可明显促进血小板的恢复,但作用较缓;其脾脏和骨髓CFU-GM、CFU-MK、CFU-S水平显著地高于对照组,表明成纤维细胞介导的G-CSF基因疗法可显著降低大剂量化疗后造血损伤程度,并明显加速受损的造血功能的恢复。

In the present study, the effects of G-CSF gene therapy was investigated on the recovery of murine hematopoietic suppression induced by high dose of cyclophosphomide (Cy) . The results showed that G-CSF gene therapy could slow down the Cy-induced decreasing of peripheral WBCs and platelets, and accerelate their recovery.It also could increase the CFU-GM, CFU - MK, CFU-S derived from the splenocyte and bone marrow cells in the chemotherapy-treated mice. The data demonstrated that fibroblast-mediated G-CSF gene therapy could significantlyreduce the hematopoietic damage to less extent, and accerelate hematopoietic recovery after chemotherapy.
