人工细胞既不是生物细胞的复制品,也不是一种特殊的活体结构,而是一种具有比较简单的生物细胞特性的人工结构制品,用于治疗某些由于器官、细胞或分子水平功能不全所致的代谢性疾患,如半渗透性微型胶囊(Semipermeable Microcapsules)就是人工细胞的一种,它是由超薄半渗透性被膜包封着酶、蛋白质、吸附剂及其它生物活性物质 An artificial cell is neither a replica of a living cell nor a specific living cell structure but an artificial structured product having a relatively simple biological cell characteristic and is used for the treatment of diseases caused by organ dysfunction due to organ, cell or molecular level Metabolic disorders, such as Semipermeable Microcapsules, are artificial cells that encapsulate enzymes, proteins, adsorbents, and other bioactive substances by ultrathin semipermeable membranes
