摘要
目的观察人脐血源基质细胞(hUCBSCs)移植对裸鼠造血损伤的修复效果。方法6.5Gy辐照裸鼠后,分别从尾静脉输入1×105个人脐血源基质细胞及生理盐水,分别于移植+1、+3、+5、+7、+10、+14、+21d观察裸鼠血象、骨髓象以及不同时相点CFU-F、CFU-GM、BFU-E、CFU-Meg动态变化。结果HUCBSCs移植组裸鼠在血象、骨髓象恢复时间、不同时相点骨髓CFU-F、CFU-GM、BFU-E、CFU-Meg等方面与对照组比较,差异有统计学意义(P<0.01)。结论HUCBSCs移植具有促进裸鼠造血损伤修复的作用。
Objective To observe the reparative effect of human umbilical cord blood stromal cells (hUCBSCs) transplantation on the hematopoiefic damage in athymic mouse. Methods To irradiate the experimental athymic mice by 6. 5Gy, and to infuse hUCBSCs or physiological saline through vena caudalis, then,to observe the change of indexes, such as the hemogram, myelogram, CFU-F, CFU-GM, BFU-E and CFU-Meg, on+ld, +3d, +5d, +7d, +10d, +14d, +21d after the transplantation. Resuits The athymic mice infused by hUCBSCs were significantly different from the control group in the recovery time of hemogram, myelogram, CFU-F, CFU-GM, BFU-E and CFU-Meg in different phases (P〈0. 01). Conclusion HUCBSCs transplantation could enhance the recovery of hematopoietic damage in athymic mouse.
