关节软骨自我更新和修复能力差。常驻间充质(结缔组织)祖细胞的数量和活性不足可能是根本原因之一。软骨祖细胞不仅存在于关节软骨的表面区域,而且存在于关节软骨的其它区域和邻近组织中,包括软骨膜(Ranvier沟)、滑膜和脂肪垫。这些细胞可能对损伤做出反应,并有助于关节软骨愈合。此外,当关节软骨受损时,骨髓基质细胞可以通过软骨下骨迁移。我们应该开发药物和方法,正确地刺激常驻祖细胞,以改善修复和抑制关节软骨退行性变化。
Articular cartilage has poor capacity of self-renewal and repair. Insufficient number and activity of resident mesenchymal (connective tissue) progenitors is likely one of the underlying reasons. Chondroprogenitors reside not only in the superficial zone of articular cartilage but also in other zones of articular cartilage and in the neighboring tissues, including perichondrium (groove of Ranvier), synovium and fat pad. These cells may respond to injury and contribute to articular cartilage healing. In addition, marrow stromal cells can migrate through subchondral bone when articular cartilage is damaged. We should develop drugs and methods that correctly stimulate resident progenitors for improvement of repair and inhibition of degenerative changes in articular cartilage.
