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
Chemical, enzymatic, and physical treatments disrupt cell membranes and help remove cellular material, including genetic material. Their conditions must be controlled because processing is intended to clear unwanted components while retaining extracellular-matrix architecture, structural proteins, and biochemical cues. The resulting balance determines how well the scaffold can support later cell adhesion, migration, proliferation, and tissue-specific organization.
Preserved extracellular-matrix architecture provides more than physical support. Structural proteins and biochemical cues create a three-dimensional environment that can influence how seeded cells attach, move, proliferate, and organize. For engineering applications, maintaining these native features helps researchers study cell–matrix interactions and may improve the scaffold’s relevance to the tissue or organ it is intended to model or support.
Source tissue, processing conditions, sterility, and immune compatibility all influence scaffold performance. The source contributes the native matrix features, while treatment conditions affect how much cellular material is removed and how much matrix structure remains. Sterility is important for practical use, and immune compatibility affects whether the engineered construct can function without an undesirable response.
Production generally involves exposing tissue or organ material to chemical, enzymatic, or physical treatments that disrupt cells, followed by washing to remove cellular components and genetic material. Processing is then evaluated according to whether the extracellular-matrix architecture, structural proteins, and biochemical cues remain sufficiently preserved. These steps require careful control because clearing cells and retaining matrix features are competing goals.
Engineers seed cells onto these three-dimensional frameworks to examine adhesion, migration, proliferation, and tissue-specific organization within a matrix environment. They also use the scaffolds to study cell–matrix interactions and to develop potential constructs for regenerative medicine. Their value lies in combining a tissue-derived structural context with experimental control over the cells placed within it.
Engineers should assess the source tissue, processing conditions, sterility, and immune compatibility before selecting a scaffold for a construct. These factors help determine whether the matrix retains useful structural and biochemical features and whether it can provide an appropriate environment for seeded cells. Such evaluation is essential because scaffold performance can vary substantially with tissue origin and processing history.
