目的:探讨兔体外软骨细胞不同代系间Ⅱ型胶原mRNA表达的差异以及人参皂甙Rb1对第2代软骨细胞Ⅱ型胶原表达的影响。
方法:在成功分离培养软骨细胞后,以细胞爬片法检测原代及第2、4代软骨细胞Ⅱ型胶原mRNA表达的差异。以浓度为0.01μmol·L -1,0.1μmol·L -1,1μmol·L -1,10μmol·L -1,100μmol·L -1的Rb1作用于贴壁3d后的第2代病理软骨细胞,观察各浓度组软骨细胞Ⅱ型胶原mRNA表达情况。
结果:原代、第2代、第4代软骨细胞Ⅱ型胶原mRNA表达的强度依次下降,适宜浓度的Rb1可增强第2代软骨细胞Ⅱ型胶原的表达,维持软骨细胞的正常表型。
结论:兔软骨细胞不同代系间Ⅱ型胶原mRNA的表达存在一定差异,人参皂甙Rb1可能有利于第2代软骨细胞Ⅱ型胶原的表达。 |

Abstract:
Objective:To study collagen Ⅱ mRNA expression of chon drocy tes in differ ent generations and the effects of ginse noside Rb1 on the expression of collagen Ⅱ mRNA of the second generation chon drocytes in rabbits.
Methods:After the rabbits’chondrocytes were cultured successfully,the expressions of collagen Ⅱ mRNA of the first,the second and the third generation chondrocytes were detec ted.Different density ginsenoside Rb1,in cluding 0.01 μmol·L -1,01 μmol·L -1,1 μmol·L -1,10 μmol·L -1and 100 μmol·L -1,were exerted to the second generat ion chondrocyte,and then the expressions of collagen ⅡmRNA were observed.
Results:The e xpression intensity of collagen Ⅱ mRNA o f the first,the second and the third generati on chondrocytes decreased gradually.The ginsenoside Rb1 with suitable density could strength en the expression of collagen Ⅱ mRNA,and restrai n the expression of specific collagen Ⅱ .
Conclusion:T he expressions of collagen Ⅱ mRNA in dif ferent generation chondrocytes is different.Ginsenoside Rb 1 may be benefit to increase the express ion of collagen Ⅱ mRNA in the second generat ion chondrocytes. |
