文题释义:
软骨细胞:
位于软骨基质内的软骨陷窝中。在陷窝的周围,有一层染色深的基质,称软骨囊。软骨细胞在软骨内的分布有一定的规律性,靠近软骨膜的软骨细胞较幼稚,体积较小,呈扁圆形,单个分布。当软骨生长时,细胞渐向软骨的深部移动,并具有较明显的软骨囊,细胞在囊内进行分裂,逐渐形成有2-8个细胞的细胞群,称为同源细胞群。软骨细胞核椭圆形,细胞质弱嗜碱性,生活时充满软骨陷窝内。
软骨基质:透明软骨基质的化学组成主要为大分子的软骨黏蛋白,其主要成分是酸性糖胺多糖(glycosaminoglycan)。软骨黏蛋白的主干是长链的透明质酸分子,其上结合了许多蛋白质链,蛋白质链上又结合了许多硫酸软骨素和硫酸角质蛋白链,故染色呈碱性。这种羽状分支的大分子结合着大量的水,大分子之间又相互结合构成分子筛,并和胶原原纤维结合在一起形成固态的结构。软骨内无血管,但由于软骨基质内富含水分(约占软骨基质的75%),营养物质易于渗透,故软骨深层的软骨细胞仍能获得必需的营养。

 

摘要
背景:
课题组在前期研究的基础上,体外分离、培养及鉴定新西兰大白兔距骨软骨细胞。
目的:探讨新西兰大白兔距骨软骨细胞体外分离、培养及鉴定的实验方法。
方法:课题组采用单纯Ⅱ型胶原酶消化法体外分离新西兰大白兔距骨软骨细胞,进行体外培养,通过形态学观察、甲苯胺蓝染色和Ⅱ型胶原蛋白免疫细胞化学染色对软骨细胞进行鉴定。
结果与结论:①倒置相差显微镜观察3代以内新西兰大白兔距骨软骨细胞呈多角形或三角形,核为圆形或椭圆形;②甲苯胺蓝染色可见新西兰大白兔距骨软骨细胞呈紫蓝色,细胞基质呈蓝色;③Ⅱ型胶原蛋白免疫细胞化学染色可见新西兰大白兔距骨软骨细胞胞浆及胞膜出现棕黄色颗粒;④实验成功建立了新西兰大白兔距骨软骨细胞体外分离、培养及鉴定体系;实验结果提示3代以内软骨细胞生长良好,保持软骨细胞稳定的生物学特征。

Abstract:

BACKGROUND: Based on the previous studies, the New Zealand rabbit talar chondrocyts were isolated, cultured and identified in vitro.
OBJECTIVE: To explore the isolation, culture and identification of New Zealand rabbit talar chondrocyts in vitro.
METHODS: The chondrocyts were isolated from the talar cartilage of New Zealand white rabbits by type II collagen enzyme digestion, and then cultured in vitro. The cells were identified by inverted phase contrast microscope, toluidine blue staining and collagen type II immunohistochemical staining.
RESULTS AND CONCLUSION: Under the inverted phase contrast microscope, most of passaged chondrocytes presented with polygonal or triangle shape and had round or oval nuclei. Toluidine blue staining showed the hyacinthine chondrocytes and blue cellular matrix. Collagen type II immunohistochemical staining showed that the chondrocytes appeared with brown granules in the cytoplasm and membrane. To conclude, a system that can isolate, culture and identify talar chondrocytes from New Zealand rabbits is successfully established. Talar chondrocytes at passages 1-3 grow well and have stable biological properties.
