大鼠椎间盘纤维环细胞的培养及鉴定
Culture and identification of rat annulus fibrosus cells
摘要
Abstract
BACKGROUND: There is not a criterion for culture of annulus fibrosus cells, thus, there is deficiency in operability and repetitiveness.OBJECTIVE: To establish the annulus cell lines and to observe their continuouschanges, in order to provide the methods and cell model for studying molecular biology in tissue engineering field.METHODS: The annulus fibrosus cells were isolated with enzyme digestion and grew as monolayer. DMEM containing 15% fetal calf serum was used in the primary culture, which was replaced by DMEM containing 10% fetal calf serum after cell passage.Morphology, structure and biological characteristics of cells were detected by an inverted phase contrast microscope. The phenotype was identified with the toluiding blue staining and immunocytochemistry.RESULTS AND CONCLUSION: The disc fibrinous ring cells were cultured in monolayer with the round or fusiformis morphology.The primary cells grew more slowly than the subculture cells. The cells displayed intense toluiding blue metachromasia; the immunohistochemical test revealed that the positive expression of type Ⅰ and Ⅱ collagen on the cells. The experiment successfully culture annulus fibrosus cells in vitro.关键词
