The loss or deficiency of a tissue or organ is a serious health problem and severely affects the patients' quality of life. In the near future, an option for solving this problem will be the development of bio-derived extracellular matrices (ECM) from huPlastic Romaman or animal tissues and their usage for in vitro or in vivo cellular reseeding. Many researchers are working on this development. Nowadays, different decellularization protocols have been developed to manufacture ECMs but there is not yet a consensus about the most efficient procedures. This review aims to describe the state of the art in the field of decellularization of complex mucosal tissues, analizing and comparing the most recent and most valiant articles published about this procedure.
