ABSTRACT
BACKGROUND:
Ligamentum flavum hypertrophy is one of the most important factors of lumbar spinal stenosis, but the molecular mechanism is stil not very clear.OBJECTIVE:
To explore the role of basic fibroblast growth factor, connective tissue growth factor and transforming growth factor β1 in hypertrophy of the lumbar ligamentum flavum.METHODS:
The ligamentum flavum samples were divided into three groups according to different diseases control group (acquired from the patients with lumbar spinal canal tumor,n=6), lumbar disc herniation (LDH) group (acquired from the patients with LDH,n=6) and lumbar spinal stenosis (LSS) group (acquired from the patients with LSS,n=6). Then the mRNA expressions of basic fibroblast growth factor, connective tissue growth factor, transforming growth factor β1 and colagen I, III, V of the ligamentum flavum were detected using real-time quantitative RT-PCR method. The roles of basic fibroblast growth factor, connective tissue growth factor and transforming growth factor β1 were explored. RESULTS ANDCONCLUSION:
The expression of basic fibroblast growth factor mRNA in the LSS group was significantly higher than that in the LDH and control groups (bothP 0.05); the expression of transforming growth factor β1 mRNA was significantly higher in the LSS group than in the LDH and control groups (bothP 0.05). This study indicate that both basic fibroblast growth factor and transforming growth factor β1 play important roles in the formation process of the lumbar ligamentum flavum hypertrophy, and the main type of the colagen in the hypertrophied ligamentum flavum is colagen I.
