随着人口平均年龄的增长,骨质疏松症和骨骼疾病的发病率继续上升。目前骨骼修复的治疗选择包括固定,刚性固定,同种异体材料和骨移植物,所有这些都有明显的局限性,特别是在老年人中。脂肪源性基质细胞(ASCs)是一种容易获得的大量间充质干细胞,在体外和体内均具有成骨能力,使其成为骨骼祖细胞的一个有希望的来源。目前的方案允许从15cc的抽脂液中收获超过100万个细胞。尽管临床使用ASCs治疗全身性炎症性疾病,但目前还没有将ASCs用于骨骼组织工程的大型人体临床试验。本文的目的是定义ASCs,描述ASCs的分离过程,回顾其成骨分化的基本生物学,讨论可用于骨组织工程的细胞类型和支架,最后探讨ASCs的成像及其在人类骨组织工程中的潜在作用。
As the average age of the population grows, the incidence of osteoporosis and skeletal diseases continues to rise. Current treatment options for skeletal repair include immobilization, rigid fixation, alloplastic materials and bone grafts, all which have significant limitations, especially in the elderly. Adipose derived stromal cells (ASCs) represent a readily available abundant supply of mesenchymal stem cells which demonstrate the ability to undergo osteogenesis in vitro and in vivo, making ASCs a promising source of skeletal progenitor cells. Current protocols allow for the harvest of over 1 million cells from only 15cc of lipoaspirate. Despite the clinical use of ASCs to treat systemic inflammatory diseases, no large human clinical trials exist using ASCs for skeletal tissue engineering. The aim of this review is to define ASCs, to describe the isolation procedure of ASCs, to review the basic biology of their osteogenic differentiation, discuss cell types and scaffolds available for bone tissue engineering and lastly to explore imaging of ASCs and their potential future role in human skeletal tissue engineering efforts.
