The bone is a regenerative tissue, capable of healing itself after fractures. However, some circumstances such as critical-size defects, malformations, and tumor destruction may exceed the skeleton's capacity for self-repair. In addition, bone mass and strength decline with age, leading to an increase in fragility fractures. Therefore, the ability to generate large numbers of patient-specific osteoblasts would have enormous clinical implications for the treatment of skeletal defects and diseases. This review will highlight recent advances in the derivation of pluripotent stem cells, and in their directed differentiation towards bone-forming osteoblasts.
骨骼是一种可再生组织,能够在骨折后自行愈合。然而,某些情况,如临界尺寸缺损、畸形和肿瘤破坏,可能超出骨骼的自我修复能力。此外,骨量和骨强度会随着年龄的增长而下降,导致脆性骨折的发生率增加。因此,生成大量患者特异性成骨细胞的能力对于骨骼缺损和疾病的治疗具有巨大的临床意义。本综述将重点介绍多能干细胞衍生及其向成骨细胞定向分化方面的最新进展。
