Adipose tissue pathologies and defects have always represented a reconstructive challenge for plastic surgeons. In more recent years, several allogenic and alloplastic materials have been developed and used as fillers for soft tissue defects. However, their clinical use has been limited by further documented complications, such as foreign-body reactions potentially affecting function, degradation over time, and the risk for immunogenicity. Tissue-engineering strategies are thus being investigated to develop methods for generating adipose tissue. This paper will discuss the current state of the art in adipose tissue engineering techniques, exploring the biomaterials used, stem cells application, culture strategies, and current regulatory framework that are in use are here described and discussed.
脂肪组织病理学和缺损一直是整形外科医生面临的重建挑战。近年来,已经开发了几种同种异体和异质材料,并用作软组织缺损的填充剂。然而,它们的临床应用受到进一步记录的并发症的限制,例如可能影响功能的异物反应、随时间降解以及免疫原性风险。因此,正在研究组织工程策略以开发生成脂肪组织的方法。本文将讨论脂肪组织工程技术的当前技术水平,探讨所使用的生物材料、干细胞应用、培养策略,以及在此描述和讨论当前正在使用的监管框架。
