摘要:
文题释义:
干细胞成骨分化:干细胞存在于多种成体组织中,包括皮肤、肌肉、骨髓和脂肪,在体外不同条件下来诱导分化成骨、软骨及其他结缔组织,因其来源广泛、分离无创伤、较低的免疫原性及生长周期短等特点,是组织工程种子细胞的重要来源。骨组织工程:是指用各种材料制备一种具有优良生物相容性、在人体内可逐步被降解吸收的细胞支架,这种仿生支架能像天然骨一样为细胞提供生存所需的三维空间,使细胞获得足够的营养物质,并进行气体交换,排除废物,细胞能够在支架上按预制形态生长,最终修复骨缺损。
结果与结论:①物理因子作为一种无创、非接触的辅助疗法对骨组织工程有着显著影响,在调控干细胞的成骨分化、促进细胞的增殖以及在骨工程支架内的生存能力方面有着积极作用。②除了激活信号通路和成骨基因转录外,物理因子还可以改善血管化、增加支架中形成的骨的体积、面积和厚度,可以促进骨整合,提高骨支架再生健康骨组织的成功率。③然而,将物理因子用于骨组织工程的研究均采用不同的实验条件,如支架类型、细胞类型及干预条件等,无法直接进行比较以确定最佳参数设置,在临床应用中,这些不同干预对促进骨折愈合的有效性研究结果也缺乏一致性,因此未来还需要进一步确定物理因子用于骨组织工程的最佳参数。④总体而言,物理因子作为一种理想的辅助疗法,在与各种生物材料结合并应用于骨组织工程方面具有巨大的潜力。

文题释义:
干细胞成骨分化:干细胞存在于多种成体组织中,包括皮肤、肌肉、骨髓和脂肪,在体外不同条件下来诱导分化成骨、软骨及其他结缔组织,因其来源广泛、分离无创伤、较低的免疫原性及生长周期短等特点,是组织工程种子细胞的重要来源。骨组织工程:是指用各种材料制备一种具有优良生物相容性、在人体内可逐步被降解吸收的细胞支架,这种仿生支架能像天然骨一样为细胞提供生存所需的三维空间,使细胞获得足够的营养物质,并进行气体交换,排除废物,细胞能够在支架上按预制形态生长,最终修复骨缺损。

大段骨缺损一直是骨科临床上未能解决的难题。虽然骨移植可以成为一种合适有效的治疗选择,但骨供体并不广泛,且移植的成功率与高感染率或疾病传播率有关[1]。骨组织工程是由生物工程、细胞移植和材料科学组成的21世纪生命科学领域的前沿交叉学科,旨在构建修复损伤骨的生物替代物[2]。骨组织工程作为一种新型的引导骨组织再生的方法成为当前的研究热点。近年来,骨组织工程为治疗骨缺损的相关研究方兴未艾,除了在天然骨的基础上对其进行优化外,也开发了各式各样的骨支架,呈现出良好的生物相容性、骨传导率以及更优力学性能的特点[3]。
