文题释义:
脐血间充质干细胞:
脐血是胎儿出生时脐带内及近胎盘侧血管内血液,是胎儿血液循环的一部分。研究表明,脐血间充质干细胞含量丰富,约占有核细胞的0.98%,该细胞为较原始细胞,有分化为造血细胞、脂肪细胞、肌肉细胞、神经细胞等潜能。目前实验研究证明,脐血间充质干细胞移植能治疗血液病、心脏疾病、脑损伤、脊髓损伤等疾病。目前也有报道脐血间充质干细胞经侧脑室注射治疗脑性瘫痪的实验研究。
神经节苷酯:是含唾液酸的糖神经鞘脂,是神经细胞膜的组成成分,在神经发生、生长、分化过程中起必不可少的作用,包括促进神经再生、促进神经轴突生长和突触形成、恢复神经支配功能、改善神经传导、促进脑电活动及其他神经电生理指标的恢复、保护细胞膜、促进细胞膜各种酶活性恢复等作用。

 

摘要
背景:
最近研究证实神经节苷脂在体外能促进脐血间充质干细胞存活及分化。
目的:观察侧脑室注射人脐血间充质干细胞及神经节苷脂对脑性瘫痪大鼠神经功能恢复的影响。
方法:受孕17 d大鼠腹腔注射脂多糖2 d,放回笼中饲养,孕鼠分娩出脑性瘫痪乳鼠60只,随机分5组:模型组10只,假移植组10只,脐血间充质干细胞移植组18只,神经节苷脂组10只,联合移植组12只。在立体定位仪下,将脐血间充质干细胞或神经节苷脂注入左侧侧脑室,假移植组注入同样体积的PBS。在移植后7,14,21,28 d分别处死2只脐血间充质干细胞移植组大鼠,移植后14 d处死2只联合移植组大鼠,进行脑组织免疫荧光染色。移植后28 d进行神经功能评估。
结果与结论:①脐血间充质干细胞能存活、迁移、分化,主要分布在侧脑室、海马、皮质。移植后14 d,联合移植组BrdU、GFAP阳性细胞数明显高于脐血间充质干细胞移植组,差异有显著性意义(P < 0.05);②神经功能评估:与模型组比较,脐血间充质干细胞移植组、神经节苷脂组、联合移植组的握持时间延长、足错误次数减少,差异有显著性意义(P < 0.05)。联合移植组优于脐血间充质干细胞移植组及神经节苷脂组,差异有显著性意义(P < 0.05);③结果表明,脐血间充质干细胞及神经节苷脂均能改善脑性瘫痪大鼠神经功能,神经节苷脂能够提高脐血间充质干细胞在大鼠脑内存活及分化,联合应用效果更好。

Abstract:

BACKGROUND: In recent years, some studies have demonstrated that ganglioside can promote survival and differentiation of umbilical blood cord mesenchymal stem cells in vitro.
OBJECTIVE: To observe the effect of injection of human umbilical blood cord mesenchymal stem cells and ganglioside into rat lateral ventricles on neurological functional recovery from cerebral palsy.
METHODS: Totally 60 cerebral palsy neonatal rats were delivered from pregnant rats which were modes were given intraperitoneal injection of lipopolysaccharide for 2 successive days on day 17 of gestation. Then those neonatal rats were randomly divided into five groups, including model group (n=10), sham transplantation group (n=10), stem cell transplantation group (n=18), ganglioside group (n=10) and combination group (n=12). Under stereotaxic instrument, umbilical blood cord mesenchymal stem cells or ganglioside were injected into left lateral ventricles of the rat brain, respectively, and the sham transplantation group was given the same volume of phosphate buffered saline. Two rats from the stem cell transplantation group were put to death for immunofluorescence staining at 7, 14, 21 and 28 days after transplantation, respectively, and two rats in the combination group were killed for immunofluorescence staining at 14 days. Besides, all rats were underwent neurologic evaluation at 28 days after transplantation.
RESULTS AND CONCLUSION: The umbilical blood cord mesenchymal stem cells could survive, migrate and differentiate, which mainly distributed in the lateral ventricle, hippocampus and cortex. At 14 days after transplantation, positive expressions of BrdU and glial fibrillary acidic protein in the combination group were significantly higher than those in the stem cell transplantation group (P < 0.05). In addition, compared with the model group, the holding time significantly prolonged and foot error times significantly decreased in the latter three groups (P < 0.05), as well as in the combination group compared with the stem cell transplantation and ganglioside groups (P < 0.05). These results indicate that umbilical blood cord mesenchymal stem cells and ganglioside can both improve neurological function of rats with cerebral palsy. Given that ganglioside can promote survival and differentiation of umbilical blood cord mesenchymal stem cells in vivo, the combined transplantation is preferred.
