Development of the Limb Synovial Joints01:07

Development of the Limb Synovial Joints

2.2K
Joints form during embryonic development in conjunction with the formation and growth of the associated bones. The embryonic tissue that gives rise to all bones, cartilage, and connective tissues of the body is called mesenchyme.
The mesenchymal stem cells differentiate into chondrocytes that form the hyaline cartilage, and later the cartilaginous model of the bone. This model further transforms into a bone. This process is known as endochondral ossification.
During development, the limbs...

科学领域:

  • 整形外科和再生医学
  • 生物材料和组织工程

背景情况:

  • 骨质突变器是研究关节发育和骨关节炎 (OA) 治疗方法的重要活体模型.
  • 结合突组织模仿了OA炎症环境,但合适的培养基仍然没有定义.
  • 脂肪酸衍生干细胞条件介质 (CM) 可能在OA中提供治疗效益.

研究的目的:

  • 在两个培养介质中研究骨质突起剂的反应性:杜尔贝科的改性基本介质 (DMEM) 和原体介质 (CHONDRO).
  • 评估脂肪衍生干细胞受条件介质 (CM) 在OA背景下对骨质突变体的治疗潜力.
  • 评估突组织存在对突体反应的影响.

主要方法:

  • 在DMEM或CHONDRO中长达30天培养了带有或没有突的骨质突扩展物.
  • 探索者接受了来自脂肪衍生干细胞 (ADSC) 的无血清条件介质 (CM) 的治疗.
  • 通过细胞因子释放 (IL-6,TNFα,IL-1β),突细胞性和蛋白质含量 (原II,Perlecan,β-galactosidase) 评估反应性,使用西方斑块和免疫组织化学.

主要成果:

  • 在DMEM培养物中,IL-6和TNFα的减少,并增加了原II (Col II) 表达.
  • 冠状腺培养物表现出增加的冠状腺细胞群,增加的珀莱肯和IL-1β水平,与可变的Col II.
  • CM治疗始终抑制了TNFα和增加了β-galactosidase,这表明无论媒介类型如何,都具有抗衰老效应.

结论:

  • DMEM提供了一个中立的环境,适合在骨质突变模型中评估疗法.
  • 冠状腺促进冠状细胞聚类和ECM合成,但可能会混实验结果.
  • CM显示了潜在的治疗效果,包括抗衰老,这需要对OA治疗进行进一步的研究.
