据报道，小鼠的品系是非常重要的DMM模型诱导，小鼠作为不同菌株有不同的OA严重性DMM后，用在129/SvEv应变水平最高，其次是C57BL6，129/SvInJ然后FVB / Ñ26。转基因的一大部分是建立在C57BL6小鼠，如PGRN-/ - 小鼠，我们在本研究中使用，这是相对容易的DMM。然而，如果转基因是基于不敏感的菌株如FVB / N小鼠，它是必要的回交这些小鼠与DMM诱导前敏感菌株。用于数字万用表诱导小鼠的性别也是非?...

骨关节炎（OA），也称为退行性关节炎，影响到世界人口的15％，超过46万人在美国，并且其特征在于滑膜炎，软骨变性和骨赘形成1。它可以是遗传，代谢，生物力学和生化因素之间复杂的相互作用的结果。 OA的基本机制继续回避科学界。目前有许多动物模型中，可以模仿OA 2,3的发病机制。它建立各种转基因小鼠的两个可用性和实验的成本效益，因为动物模型小鼠中是很重要的。其中各种不同的实验OA模型中，手术引起的内侧半月板（DMM）模型的不稳定是由于其良好的重现性和OA的发展过程中一个相对进展较慢一个广为接受的OA模型。这两个属性有是关键的不同处理或转基因3-8 OA进展的评估。然而，外科手术的OA模型的一致性在外科手术，其结果是受多种因素影响，手术小鼠模型中的应用是有限的。 的progranulin（PGRN）是表示在各种细胞多功能生长因子。它是已知的PGRN起着各种生理和疾病过程，如伤口愈合9，肿瘤10和炎症11-15的关键作用。研究还表明，PGRN的不足可引起神经系统的退化性疾病在人类和小鼠16-18。它是已知的PGRN表达在人关节软骨，其水平是在患者的骨关节炎和类风湿关节炎的19软骨显著升高。此外，PGRN也起着软骨细胞增殖20，分化和软骨内至关重要的作用生长板的发育21,22中骨化。最近，我们报道了PGRN通过结合TNF受体拮抗TNF-α和表现出抗炎作用在炎性关节炎模型13,14,23,24。然而，PGRN的在OA中的作用，特别是在体内 ，仍然是一个谜。在此，我们提出的方法诱导手术DMM模型，并通过在WT和PGRN-/建立数字万用表模型研究PGRN的在OA发展中的作用 - 小鼠。

内侧半月板不稳定（DMM）模型是研究在骨关节炎（OA） 在体内的致病众多的关节炎相关分子的病理生理作用的一个重要工具。然而，详细的，尤其是可视化协议，用于在小鼠体内建立这种复杂的模型，无法使用。在此我们利用野生型和progranulin的（PGRN）的 - / - 小鼠为例子来介绍一种协议，用于诱导DMM模型小鼠，与OA相比下成立了这个手术引起的模型的发作。在老鼠身上进行的操作要么假手术，这只是开了关节囊，或数字万用表操作，这将削减MENISCO，胫骨韧带，造成内侧半月板不稳定。用组织学检测（ 如番红O染色），办公自动化相关基因的表达，降解软骨细胞外基质分子和骨赘骨关节炎形式严重性进行评估通报BULLETIN。 DMM操作成功诱导的OA发生和发展中都野生型和PGRN-/ - 小鼠，并导致了在此手术诱导模型更严重的表型OA PGNR生长因子损失。
