摘要
终末分化是软骨细胞获得分化的默认途径,包括肥大与凋亡两种方式。无论是在骨组织生理条件下的软骨生长板形成及内源性成骨骨化,还是骨关节炎病理情况时的软骨表型改变,皆存在有相关分化过程的发生。组蛋白去乙酰化酶对于软骨细胞的生长、维持和增殖方面具有重要意义。它可通过调节基因表达和激活相关转录因子的方式介导某些疾病的发展,但目前其具体的分子生物学和生物力学机制仍不明确。本文将从生物物理学角度对组蛋白去乙酰化酶在软骨组织终末分化过程中的参与机制以及对于软骨组织工程应用价值进行总结和讨论。
Terminal differentiation is the default pathway for chondrocytes to differentiate,which include hypertrophy and apoptosis.Whether it is cartilage growth plate formation under bone physiological conditions and endogenous cartilage osteogenesis,or cartilage phenotypic changes in the pathological condition of osteoarthritis,there is a related differentiation process.Histone deacetylases are important for the growth,maintenance and proliferation of chondrocytes.They mediate the development of certain diseases by regulating gene expression and activating related transcription factors.However,their specific molecular biology and biomechanical mechanisms are still unclear.In this paper,the participation mechanism of histone deacetylases in the terminal differentiation of cartilage tissue and the application value of cartilage tissue engineering will be summarized and discussed from the perspective of biophysics.
