Cartilage and joint damage easily degenerates cartilage and turns into osteoarthritis (OA), which seriously affects human life and work, and has no cure currently. The temporal and spatial changes of multiple microenvironments upon the damage of cartilage and joint are noticed, including the emergences of inflammation, bone remodeling, blood vessels, and nerves, as well as alterations of extracellular and pericellular matrix, oxygen tension, biomechanics, underneath articular cartilage tissues, and pH value. This review summarizes the existing literatures on microenvironmental changes, mechanisms, and their negative effects on cartilage regeneration following cartilage and joint damage. We conclude that time-dependently rebuilding the multiple normal microenvironments of damaged cartilage is the key for cartilage regeneration after systematic studies for the timing and correlations of various microenvironment changes.
软骨和关节损伤容易使软骨退化并转化为骨关节炎(OA),严重影响人类的生活和工作,目前尚无治愈方法。软骨和关节损伤后,多个微环境的时空变化受到关注,包括炎症、骨重塑、血管和神经的出现,以及细胞外和细胞周基质、氧张力、生物力学、关节下软骨组织和 pH 值的改变。本综述总结了关于软骨和关节损伤后微环境变化、机制及其对软骨再生负面影响的现有文献。我们的结论是,在系统研究各种微环境变化的时间和相关性之后,随时间重建受损软骨的多个正常微环境是软骨再生的关键。
