文题释义:
细胞共培养:
将 2 种不同的细胞共同培养,主要利用细胞之间相互接触,诱导一种细胞向另外一种细胞分化或诱导细胞自身分化,维持细胞功能和活力,对细胞增殖进行调控。
胶原蛋白类型:胶原蛋白有不同的类型,目前为止已经发现了几十种。其中Ⅰ,Ⅲ型主要存在于皮肤血管等结缔组织中;Ⅱ型主要由软骨细胞产生,多存在于骨骼、关节、肌腱等组织;Ⅶ型主要存在于子宫胎盘中。

 

摘要
背景
:膝关节软骨损伤后修复较困难。有研究发现将关节软骨细胞和滑膜间充质干细胞混合培养接种于壳聚糖支架材料中,均可以形成软骨基质。
目的:观察滑膜间充质干细胞与软骨细胞与壳聚糖/Ⅰ型胶原复合支架材料对膝关节软骨缺损的修复情况。
方法:将大鼠膝关节滑膜间充质干细胞及软骨细胞按1∶2比例共培养于壳聚糖/Ⅰ型胶原复合支架材料中,将此复合材料移植于膝关节软骨缺损模型大鼠膝关节缺损处进行修复。
结果与结论:①组织学变化:苏木精-伊红染色、甲苯胺蓝染色及番红O染色显示,植入后4,8,12周,大鼠膝关节软骨细胞逐渐增多;②软骨样组织标记物Ⅱ型胶原表达:免疫组织化学染色显示,移植后4,8,12周,大鼠膝关节软骨组织细胞及细胞基质可见Ⅱ型胶原阳性表达。③结果证实,滑膜间充质干细胞与软骨细胞混合培养于壳聚糖/Ⅰ型胶原复合支架材料中,在体内环境下能够形成软骨样组织,有利于损伤膝关节软骨缺损的修复。

Abstract:

BACKGROUND: As is known to all, it is difficult to repair cartilage defect of the knee joint. Fortunately, it is reported that a chitosan scaffold with the mixture of synovial mesenchymal stem cells and chondrocytes enables the formation of cartilage matrix.
OBJECTIVE: To observe the chondrogenic differentiation of synovial mesenchymal stem cells co-cultured with chondrocytes on a chitosan/type I collagen composite scaffold after being transplanted into an animal model.
METHODS: The synovial mesenchymal stem cells and chondrocytes harvested from the knee joint of Sprague-Dawley rats were co-cultured at a ratio of 1:2 on the chitosan/type I collagen composite scaffolds and transplanted into the defect site of the knee joint in rat models of cartilage defect of the knee joint.
RESULTS AND CONCLUSION: After 4, 8, 12 weeks, the hematoxylin-eosin staining, the toluidine blue staining of aggrecan, and safranine O staining showed that there were increasing chondrocytes in the rat knee joint. The immunohistochemical staining of type II collagen showed the positive expression of type II collagen in the cartilage tissues and extracellular matrix of the knee joint. To conclude, the combination of two kinds of cells cultured in the chitosan/type II collagen composite scaffold can form cartilage-like tissues in vivo, and improve the quality of cartilage repair.
