Figure 1. Hierarchical classification of adipose tissue derivatives. Adipose tissue can be processed into three major categories: cellular and micro-fragmented derivatives, including SVF, ADSCs, nanofat, SVF-gel, and CEFFE; matrix-enriched and decellularized derivatives, including AMC, ACF, and adECM; and membrane or film-like constructs, including ADF and AAF. SVF: Stromal vascular fraction; ADSCs: adipose-derived stem cells; SVF-gel: stromal vascular fraction gel; CEFFE: cell-free fat extract; AMC: adipose matrix complex; ACF: adipose collagen fragment; adECM: decellularized adipose extracellular matrix; ADF: adipose-derived matrix film; AAF: acellular adipose matrix-derived film.
