Functional biomaterials that are capable of effectively carrying therapeutic agents and specifically delivering therapeutics to pathological sites have been widely investigated over decades. Recently, cellular carriers and cell derivative-based bio-hybrid delivery systems have drawn extensive attention as a promising branch of therapeutic delivery systems, owing to their low immunogenicity and intriguing biomimetic capabilities. Various approaches for the fabrication of these biomimetic carriers have been developed, and some products have already been commercialized as well. In this review, we summarized various processing methods for engineering cell-derived biomimetic drug delivery systems, and discussed their future outlooks.
