摘要:

背景:由于半月板仅红区有血供,其营养主要来自关节内的滑液。半月板损伤后,由于半月板自身愈合能力差,半月板无血供区域几乎无法愈合。

目的:分析转化生长因子β3在大鼠半月板发育过程中表达情况及特点。

方法:选取鼠龄1,7,14,21,28,35 d的Wistar大鼠半月板,用免疫组织化学和RT-PCR方法分别检测随不同鼠龄半月板内转化生长因子β3的表达部位及表达量化。

结果与结论:免疫组织化学发现大鼠由出生到成鼠过程中,转化生长因子β3表达从关节囊开始逐渐扩展至红区、红白区、白区;RT-PCR结果显示不同鼠龄的半月板中转化生长因子β3均可见表达,发育过程中转化生长因子β3表达逐渐增加,生长至成鼠(成鼠标准100 g/只)后表达趋于稳定。

Abstract:

BACKGROUND: Since the meniscal blood supply is only in the red zone, the synovial fluid becomes the main nutrition source of the meniscus. As its poor self-healing ability, the meniscus is almost impossible to heal in non-blood supply regions.
OBJECTIVE: To investigate the expression and characteristics of transforming growth factor-β3 in the rat meniscus during postnatal development.
METHODS: Meniscus tissues of Wistar rats with different ages (1, 7, 14, 21, 28, 35 days) were adopted, and immunohistochemistry and RT-PCR methods were performed to detect the location and expression pattern of transforming growth factor-β3 within the meniscus.
RESULTS AND CONCLUSION: Immunohistochemistry results revealed that the expression of transforming growth factor-β3 started from the joint capsule, and gradually extended to the red zone, gray zone, and white area; RT-PCR results showed the mRNA expression of transforming growth factor-β3 in the rat meniscus at different ages, and during development process gradually increased until adult stage (rat weight > 100 g), which remained relatively stable.
