摘要:

人华通胶间充质干细胞具有优异的增殖潜力、分化能力、低免疫原性,并且容易获取,但既往少见其在治疗缺血性脑卒中方面应用的报道,其治疗效果仍需实验验证。为此,实验设计阻塞大鼠大脑中动脉闭塞48h建立缺血性脑卒中模型,经尾静脉移植人华通胶间充质干细胞。4周后发现大鼠神经功能明显改善,人华通胶间充质干细胞更多地归巢到大鼠缺血额叶皮质中,并在此区域分化为神经元样细胞。结果表明人华通胶间充质干细胞能够在缺血性脑卒中大鼠缺血部位分化为神经元样细胞,进而改善其神经行为能力。

Abstract:

Human Wharton’s jelly-derived mesenchymal stem cells (hWJ-MSCs) have excellent proliferative ability, differentiation ability, low immunogenicity, and can be easily obtained. However, there are few studies on their application in the treatment of ischemic stroke, therefore their therapeutic effect requires further verification. In this study, hWJ-MSCs were transplanted into an ischemic stroke rat model via the tail vein 48 hours after transient middle cerebral artery occlusion. After 4 weeks, neurological functions of the rats implanted with hWJ-MSCs were significantly recovered. Furthermore, many hWJ-MSCs homed to the ischemic frontal cortex whereby they differentiated into neuron-like cells at this region. These results confirm that hWJ-MSCs transplanted into the ischemic stroke rat can differentiate into neuron-like cells to improve rat neurological function and behavior.
