再程序化脂肪干细胞移植治疗大鼠脊髓损伤的机制
Mechanism of reprogrammed adipose derived stem cells transplantation promoting ;recovery of injured spinal cord
摘要
Abstract
Objective To investigate the therapeutic effects of reprogrammed adipose derived stem cell ( ADSCs) in a rat model of spinal cord injury ( SCI) .Methods ADSCs from rats were cultured in vitro and then purified and identified, and genetically modified ADSCs with the neurogenin2 ( Ngn2 ) gene.48 adult female Sprague-Dawley rats were randomly assigned to three groups, the control, ADSC, and Ngn2-ADSCs groups.The hind-limb motor function of all rats was recorded using the Basso, Beattie, and Bresnahan ( BBB ) locomotor rating scale for 8 weeks. Subsequently, haematoxylineosin ( HE) staining, immunohistochemistry were performed.Results Ngn2-ADSCs transplantation group in motor function score, glial scar formation after spinal cord injury and pathological changes in the secretion of neurotrophic factor BDNF and VEGF were significantly better than the other groups.Conclusion Ngn2-ADSCs after transplantation can effectively survive and differentiate into nerve cells, inhibit glial scar formation, reduce spinal cord injury voids, increase BDNF and VEGF expression, and to improve recovery of motor function in SCI rats in a more efficient way than that with ADSCs alone.关键词
