2、退行性脊柱侧凸小鼠模型
退行性脊柱侧凸(DKS)是一种复杂的脊柱畸形疾病,与骨骼、肌肉、椎间盘和小关节的退化有关。本研究的目的是建立退行性脊柱侧凸动物模型,揭示DKS的关键病理特征,并验证衰老加速小鼠(SAMP8)的退行性变化。将30只雄性小鼠分为2组:10只双足C57BL/6J小鼠作为对照组,20只双足SAMP8小鼠作为实验组。小鼠在全身麻醉下双足行走。分别在术后 4、8 和12周使用X光片和体内显微CT图像确定脊柱侧凸的发生率和骨质量。在手术后12周处死后进行肌肉样品的组织形态学研究。第12周,C57BL/6J和SAMP8组后凸畸形发生率分别为50%和100%。总体而言,双足SAMP8组后凸畸形的发生率和角度显着高于C57BL/6J组(44.7°±6.2° vs. 84.3°±10.3°,P<0.001)。基于整个脊柱的3D重建,在双足SAMP8小鼠中观察到椎间盘的退化,包括椎间盘高度的降低和椎体骨赘的形成。与双足C57BL/6J组相比,双足SAMP8组的骨体积比(BV/TV) 显着抑制。此外,椎旁肌肉组织的HE染色和Mason染色显示双足SAMP8组肌肉出现慢性炎症和纤维化。SAMP8小鼠模型可作为DKS的临床模型,肌肉骨骼系统的加速老化促进了脊柱后凸的发展。
