脂肪来源干细胞在骨／软骨／椎间盘／肌腱组织修复中的应用

骨、软骨、椎间盘、肌腱等组织的自体细胞在体外培养、扩增困难，因此很难真正用于组织的缺损修复。干细胞具有自我更新和向多种组织定向诱导分化的特性，近年来干细胞研究的不断发展为其应用于矫形外科组织再生修复提供了可能。由于脂防来源问充质细胞（ASC）来源丰富、取材容易，近来备受研究者青睐，已被越来越多地应用于干细胞和组织工程领域。主要针对ASC在矫形外科骨，软骨／椎间盘／肌腱等组织修复中的应用作一综述。最近的ASC体内缺损修复结果为其应用于临床矫形外科组织修复的潜能提供了研究依据：

Application of adipose-derived mesenchymal cells in bone/cartilage/intervertebral disc/tendon tissues repair

Autologous cells of bone, cartilage, intervertebral disc and tendon, are hard to be cultured and proliferate in vitro and thus have difficulty to be introduced in the repair of damaged tissue. Stem cells have the ability to self-renew and differentiate into many tissue types. Recent progress in stem cell research has led to an enthusiastic effort to utilize stem cells for orthopaedic tissue regeneration. Due to the abundance and easiness of harvest, adipose-derived mesenchymal celI(ASC) is an attractive, readily available aduh stem cell that has become increasingly popular for use in stem cell and tissue engineering applications. This review focuses on the use of ASC in orthopaedic tissue repair. Recent results from in vivo defect repair utilizing ASC suggested the great potential of ACS in clinical orthopaedic tissue regeneration.
