摘要:

背景:到目前为止,脐带间充质干细胞通过肌肉注射到体内后各器官的短期变化反应已有相关报道,但多次肌肉注射后,健康大鼠各器官远期变化的研究极少。

目的:观察大鼠肌肉注射异种脐带间充质干细胞的安全性。
方法:健康雄性SPF级Wistar大鼠60只随机均分为6组:正常组(肌肉注射脐带间充质干细胞的悬浮液——0.01 mol/L PBS),培养液组(肌肉注射脐带间充质干细胞的培养液——DMEM培养液),上清液组(肌肉注射培养脐带间充质干细胞的上清液),脐带间充质干细胞注射低剂量组(肌肉注射脐带间充质干细胞0.25×105个),脐带间充质干细胞中剂量组(肌肉注射脐带间充质干细胞1.0×105个),脐带间充质干细胞高剂量组(肌肉注射脐带间充质干细胞4.0×105个)。每只大鼠四肢各注射0.2 mL,共0.8 mL,于实验第1周和第4周分别注射1次,注射前后留取空腹血作生化检查。实验第8周末解剖大鼠,作肝脏、肺脏、脑、脾脏、肾脏及注射部位肌肉病理切片。

结果与结论:所有大鼠肌肉注射前后的肝功、肾功,肝脏、肺脏、脑、脾脏、肾脏及注射部位肌肉的病理切片均在正常范围内。肌肉注射异种脐带间充质干细胞对肝脏、肺脏、脑、脾脏、肾脏及注射部位肌肉无不良影响。说明在一定的肌注剂量范围内,大鼠肌肉注射异种脐带间充质干细胞安全可靠。

Abstract:

BACKGROUND: So far, the short-term changes of various organs after injection of umbilical cord mesenchymal stem cells have been reported, but there are few studies on the long-term changes of various organs in healthy rats after repeated intramuscular injection of umbilical cord mesenchymal stem cells.

OBJECTIVE: To observe the security of intramuscular injection of heterogeneous umbilical cord mesenchymal stem cells.
METHODS: Sixty male SPF Wistar rats were divided into six groups randomly: normal group (suspension liquid of umbilical cord mesenchymal stem cells); control group with culture solution; supernatant group (supernatant of human umbilical cord mesenchymal stem cells); low concentration group (0.25×105 human umbilical cord mesenchymal stem cells); moderate concentration group (1.0×105 human umbilical cord mesenchymal stem cells); high concentration group (4.0×105 human umbilical cord mesenchymal stem cells). Each rat was injected 0.8 mL liquid in muscle, 0.2 mL in each limb, twice at weeks 1 and 4. Biochemical tests were conducted before and after injection. At the end of 8 weeks, all the rats were killed and hematoxylin-eosin staining was done with the liver, spleen, lung, kidney, brain and muscle.
RESULTS AND CONCLUSION: There was no abnormal change about biochemical tests and hematoxylin-eosin staining after the intramuscular injection of heterogeneous umbilical cord mesenchymal stem cells. No significant alteration was observed in the liver, spleen, lung, kidney, brain, and muscle of the limb after the injection of heterogeneous umbilical cord mesenchymal stem cells under suitable concentration. These findings indicate intramuscular injection of heterogeneous umbilical cord mesenchymal stem cells at certain concentrations is safe and reliable.
