摘要:

背景:骨质疏松症的药物治疗效果不佳,干细胞移植治疗成为热点。
目的:探讨胚胎干细胞移植治疗雌激素缺乏致骨质疏松症的疗效。
方法:雌性健康C57BL/6小鼠30只,随机分为假手术组、模型组、治疗组,每组10只。建立卵巢摘除术后骨质疏松症模型,治疗组造模后1 d通过小鼠尾静脉注射胚胎干细胞,其他两组不进行任何干预。治疗10 h采用流式细胞仪检测T淋巴细胞凋亡程度,治疗后3 d运用ELISA测定小鼠血清肿瘤坏死因子α水平,治疗1个月利用micro-CT扫描检测小鼠股骨骨小梁数量和骨密度。
结果与结论:模型组股骨骨小梁数量及骨密度较假手术组均有一定程度的降低,血清肿瘤坏死因子α水平较假手术组升高。通过尾静脉注射胚胎干细胞后,治疗组股骨骨小梁数量及骨体积分数有一定的提高,肿瘤坏死因子α表达水平降低,T淋巴细胞凋亡数量增多,与模型组相比差异有显著性意义(P < 0.05)。说明胚胎干细胞治疗骨质疏松症有一定的效果,可能是通过其免疫调控能力发挥作用的。

Abstract:

BACKGROUND: Because of poor therapeutic effects of drug treatment, stem cell transplantation has become a hot spot in the treatment of osteoporosis.
OBJECTIVE: To investigate the therapeutic efficacy of embryonic stem cell transplantation in the treatment of estrogen deficiency-induced osteoporosis.
METHODS: Thirty female healthy C57BL/6 mice were randomly divided into model, sham-operated, and treatment groups, with 10 mice in each group. Ovariectomized models were established. In the treatment group, embryonic stem cells were injected by tail vein at 1 day after modeling, and there was no treatment in the other two groups. After 10 hours of treatment, flow cytometry was used to detect the apoptosis of T-lymphocytes; after 3 days of treatment, ELISA assay was used to detect the level of tumor necrosis factor-α in mouse serum; after
1 month of treatment, micro-CT was employed to determine the number of bone trabeculae and bone mineral density.
RESULTS AND CONCLUSION: Compared with the sham-operated group, the number of bone trabeculae and bone mineral density were lower in the model group, while the serum level of tumor necrosis factor-α was higher in the model group. After embryonic stem cell transplantation via the tail vein, the number of bone trabeculae and the bone volume fraction were increased certainly, the serum level of umor necrosis factor-α was decreased, and the number of apoptotic T-lymphocytes was increased in the treatment group, which significantly differed from those in the model group (P < 0.05). These findings indicate that embryonic stem cell therapy has a certain effect on the treatment of osteoporosis, which may play a role through immune regulation.
