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
Scaffold architecture and biochemical cues give introduced cells the physical space and biological signals needed to organize within a construct. Architecture influences where cells can attach and move, while biochemical cues support adhesion, proliferation, and maturation. Designing these features for the target tissue helps determine whether the construct develops organized, functional characteristics rather than simply containing a population of cells.
These processes represent different requirements for building tissue within a scaffold. Adhesion allows cells to remain associated with the material, migration helps them occupy available regions, proliferation increases cellular coverage, and maturation supports the development of tissue functions. Supporting all four is important because success depends on more than initial cell attachment or the presence of cells at the construct surface.
Uniform distribution depends on how effectively cells can occupy the scaffold and receive nutrients throughout its structure. Scaffold architecture, cell migration, and nutrient transport all influence whether populated regions develop evenly or remain concentrated in particular areas. Assessing distribution is therefore essential when judging construct quality, because uneven coverage can limit the restoration of structural and functional features.
The starting material may be biological or synthetic, but either scaffold must provide suitable architecture and biochemical cues for the selected cells. The central design question is whether the material supports adhesion, migration, proliferation, and maturation under controlled culture conditions. Comparing these scaffold types therefore focuses on how their structural and biochemical properties influence cell behavior and tissue development.
A typical workflow begins by preparing the biological or synthetic scaffold so that its architecture and biochemical cues suit the target tissue. Researchers then introduce selected cells and maintain the construct under controlled culture conditions. During culture, they support and assess cellular adhesion, migration, proliferation, and maturation, while also considering cell distribution, nutrient transport, and eventual tissue integration.
Controlled culture conditions provide a consistent environment in which cells can remain associated with the scaffold and progress through migration, proliferation, and maturation. They also help researchers evaluate whether nutrients reach the construct adequately and whether cells distribute throughout its structure. Maintaining these conditions is consequently important for producing reproducible tissue models or regenerative grafts.
Bioengineers use recellularized scaffolds to create tissue models, evaluate therapies, and develop regenerative grafts for damaged tissue. These constructs can support investigation of cell–matrix interactions while also providing a setting in which tissue formation and scaffold integration can be examined. The approach is especially relevant when researchers need to connect cellular behavior with structural and functional tissue outcomes.
