This protocol describes decellularization of Sprague Dawley rat kidneys by antegrade perfusion of detergents through the vasculature, producing acellular renal extracellular matrices that serve as templates for repopulation with human renal epithelial cells. Recellularization and use of the resazurin perfusion assay to monitor growth is performed within specially-designed perfusion bioreactors.

In the past many in vitro culture systems -- mainly monolayer cultures -- often suffered from the disadvantage that differentiated primary cells had a relatively short life-span and de-differentiated during culture. As a consequence, most of their organ-specific functions were lost rapidly. Thus, in order to reproduce better conditions for these cells in vitro, modifications and adaptations have been made to conventional monolayer cultures.
FAQs
Physical, chemical, and enzymatic treatments disrupt and remove cellular components, but the process must be controlled carefully. Excessive or poorly controlled processing can compromise the extracellular matrix architecture, composition, or mechanical properties that give the scaffold its functional value. Preserving these features helps maintain a three-dimensional environment capable of supporting subsequent cell attachment, migration, and tissue remodeling.
These matrix features determine how closely the material retains the structural and biochemical conditions associated with its original tissue. Architecture provides spatial organization, composition supplies biochemical cues, and mechanical properties influence the scaffold’s physical behavior. Maintaining all three is important because damage in any area may reduce the material’s ability to support tissue repair or guide tissue-specific structure formation.
After cells are introduced, the scaffold’s preserved three-dimensional framework can support attachment and migration while providing a setting for remodeling. These interactions help determine how cells organize within the material and whether they contribute to tissue formation. In bioengineering, researchers therefore examine not only whether cells populate the scaffold, but also whether the resulting organization reflects tissue-specific structures.
Preparation begins with decellularization using physical, chemical, or enzymatic treatments to remove cellular components. Researchers then assess whether the resulting material retains suitable matrix architecture, composition, and mechanical properties. Further evaluation addresses biocompatibility and recellularization, along with the scaffold’s ability to support cell attachment, migration, remodeling, and formation of tissue-specific structures.
Researchers use this approach when they need a biological three-dimensional framework for tissue engineering or regenerative medicine. Its value lies in combining removal of cellular components with retention of extracellular matrix features that may support repair. The approach is especially relevant when investigators want to study recellularization and whether a matrix can guide the development of tissue-specific structures.
Evaluation should consider biocompatibility, recellularization, and preservation of the matrix properties that support function. Researchers also examine whether cells attach, migrate, and remodel the material, and whether these activities contribute to tissue-specific organization. Together, these outcomes indicate whether the scaffold provides more than a physical framework and can support the intended tissue-repair process.
