The purpose of this experimental study is evaluation of the effect of BMSCs Condition Media and Methylprednisolone in TGF-β expression and functional recovery after acute spinal cord injury in adult wistar rat.
After an acute spinal cord injury, MP and BMSC-CM were injected intraperitoneally and the recovery rate was evaluated by BBB and narrow beam test. Real time PCR, H[et]E staining, cavity formation and stereology was done after 12 weeks post injury.
There were significant differences in functional recovery between MP+CM group, relative to other groups. TGF-β1 expression decreased in MP+CM group compared to the control group. Cavity size in experimental groups decreased compared to the control group. The mean volume of spinal cord demonstrated a significant increase in the MP+CM group in comparison to the other experimental groups.
Simultaneous use of MP and BMSC-CM will improve recovery from the spinal cord injury, reduce inflammation and improve functional recovery (Tab. 1, Fig. 8, Ref. 26).
本实验研究的目的是评估骨髓间充质干细胞条件培养基和甲基强的松龙对成年Wistar大鼠急性脊髓损伤后转化生长因子-β表达及功能恢复的影响。
急性脊髓损伤后,腹腔注射甲基强的松龙和骨髓间充质干细胞条件培养基,通过BBB评分和窄束试验评估恢复率。损伤后12周进行实时聚合酶链反应、苏木精-伊红染色、空洞形成及体视学分析。
与其他组相比,甲基强的松龙+条件培养基组在功能恢复方面存在显著差异。与对照组相比,甲基强的松龙+条件培养基组转化生长因子-β1表达降低。与对照组相比,实验组空洞大小减小。与其他实验组相比,甲基强的松龙+条件培养基组脊髓平均体积显著增加。
同时使用甲基强的松龙和骨髓间充质干细胞条件培养基可改善脊髓损伤后的恢复,减轻炎症并改善功能恢复(表1,图8,参考文献26)。
