Tissue regeneration strategies have been greatly evolving in the last years due to the use of more realistic approaches. These approaches rely in the use of biomaterials for the development of three dimensional (3D) structures that emulate the\ in vivo\ microenvironment of different tissues. Recently, extracellular matrices (ECM) secreted by cells have been caught a great deal of attention as an attractive biomaterial for the development 3D structures. In fact, different cells and/or different cellular culture conditions gave rise to different ECM{\textquoteright}s compositions, which can be used for the development of more physiologically relevant 3D structures. Nevertheless, the recovery of cell-derived ECM requires the use of a proper decellularization protocol. Herein, we report a decellularization protocol to recover the ECM produced by human adipose derived stem cells. This protocol comprises multiple steps (chemical, physical or enzymatic) which are described here in more detail. Furthermore, it is describe the methods that have been used to evaluate the effectiveness of this decellularization protocol. Overall, this protocol enables the production of hASCs-derived matrices that can be further used for the production of more physiologically relevant 3D\ in vitro\ models for tissue regeneration strategies.
