Perfusion decellularization is a novel technique to produce whole liver scaffolds that retains the organ's extracellular matrix composition and microarchitecture. Herein, the method of preparing whole organ scaffolds using perfusion decellularization and subsequent repopulation with hepatocytes is described. Functional and transplantable liver grafts can be generated using this technique.

FAQs
Each treatment targets a different part of the cellular material. Detergents disrupt cell membranes, enzymes help break down nucleic acids, and physical treatments support the removal of cellular components. Combining these approaches can improve decellularization, but processing must remain controlled so the extracellular matrix retains its three-dimensional organization and biochemical cues.
Removing cellular material can reduce immunogenicity, meaning the scaffold is less likely to provoke an unwanted response from a recipient. However, overly damaging processing may compromise the matrix structure and biochemical signals that guide cell behavior. Maintaining this balance is therefore important because the remaining scaffold must support attachment, migration, and differentiation after reseeding.
The three-dimensional architecture and biochemical cues of the extracellular matrix are central to the scaffold’s function. Architecture provides a structural environment for newly introduced cells, while biochemical cues can influence how those cells behave. Preserving both features helps decellularized tissue more closely reproduce aspects of native tissue than a matrix that has been substantially damaged during processing.
A typical workflow begins with donor tissue and applies controlled chemical and physical treatments to disrupt membranes and remove cellular components. Enzymatic treatment can also target nucleic acids. The resulting matrix is then used as a scaffold, either for research directly or after reseeding with recipient or cultured cells, depending on the intended bioengineering application.
Researchers may choose decellularized tissues when they need a biomaterial that retains native tissue architecture and matrix-associated biochemical cues. These properties can support cell attachment, migration, and differentiation after reseeding. Accordingly, the approach is relevant to engineered organs, tissue repair, biomaterial development, and experiments that require a closer representation of native tissue structure.
In disease modeling, a decellularized scaffold can provide tissue-specific architecture for studying how cells interact with a matrix. In regenerative medicine, the same type of scaffold can be reseeded with recipient or cultured cells to explore tissue repair or engineered organs. These applications connect matrix preservation with efforts to reproduce biologically relevant tissue environments.
