摘要:

背景:骨髓间充质干细胞对骨和软骨在细胞水平的发育和再生至关重要,其数量缺失和功能受损被广泛认为是骨关节炎病因之一。

 

目的:探讨骨关节炎患者骨髓间充质干细胞功能状态与病情进展的关系。

 

方法:2013年7月至2014年10月间收集3组病例,每组10例,分别为对照组、轻度骨关节炎患者组、重度骨关节炎患者组。获取3组患者股骨或胫骨骨髓5 mL分离培养骨髓间充质干细胞,培养至3代时采用CCK-8法检测各组患者骨髓间充质干细胞的增殖能力,成软骨诱导14 d后行甲苯胺蓝染色鉴定,Real time PCR法检测对照组诱导后软骨细胞特征基因Aggrecan、Col2A1的表达。

 

结果与结论:骨髓间充质干细胞体外培养后贴壁生长,胞浆含有较大的颗粒,核卵圆形,细胞呈多角形、梭形,有多个大小不一的突起,细胞分裂相多见。对照组增殖能力最强,重度骨关节炎患者组增殖能力最弱,但均在培养1周后进入平台期。成软骨诱导14 d后细胞呈多角形、类圆形改变,紫红色异染颗粒分布于胞浆外围。对照组诱导后软骨细胞特征基因Aggrecan、Col2A1有高表达趋势。结果表明骨关节炎患者骨髓间充质干细胞功能状态与病情严重程度成负相关,其功能状态影响骨关节炎患者的病情进展。

Abstract:

BACKGROUND: Bone marrow mesenchymal stem cells are crucial for bone and cartilage development and regeneration at a cellular level. Insufficient quantity and functional impairment of bone marrow mesenchymal stem cells is widely considered to be one of osteoarthritis causes.

OBJECTIVE: To explore the relationship between the functional status of bone marrow mesenchymal stem cells and disease progression in osteoarthritis patients.
METHODS: Thirty patients with osteoarthritis were enrolled from July 2013 to October 2014, and divided into control, mild osteoarthritis, and severe osteoarthritis groups, with 10 cases in each group. 5 mL bone marrow from the femur or tibia was extracted from each patient to isolate and culture bone marrow mesenchymal stem cells. Proliferation ability of cells at passage 3 was detected using cell counting kit-8; toluidine blue staining was performed at 14 days after chondrogenic induction; real-time PCR was used to detect the mRNA expression of Aggrecan and Col2A1 in the control group after chondrogenic induction.
RESULTS AND CONCLUSION: After in vitro culture, bone marrow mesenchymal stem cells grew adherently in polygonal and fusiform shape with multiple processes at uniform size. The cytoplasm contained larger particles and the nuclei were ovoid. Most of cells were in cell division phase. The proliferation ability was strongest in the control group and weakest in the severe osteoarthritis group. Cells from the three groups were all at plateau phase after 1 week culture. At 14 days after chondrogenic induction, the cells were polygonal and quasi-circular, and purple metachromatic granules distributed outside of the cytoplasm. The expression of Aggrecan and Col2A1 in the control group displayed an overexpression trend. These findings indicate that the functional status of bone marrow mesenchymal stem cells from osteoarthritis patients is negatively correlated with the severity of disease, which can influence the disease progression in osteoarthritis patients.
