Decellularization is a research area focused on removing cellular components from tissues or organs while preserving the structural and functional integrity of the extracellular matrix. This process involves washing tissues with detergents or enzymes to strip away cells, leaving behind a scaffold that can be repopulated with new cells. Decellularized tissues can be used in regenerative medicine applications, such as tissue engineering and organ transplantation. The goal of decellularization is to create biocompatible scaffolds that can promote cell growth, tissue regeneration, and ultimately, restore organ function.
