Purpose of the Study:
- To optimize the preparation of decellularized liver biologic scaffolds using gradient ionic detergents.
- To analyze the immunogenicity and biocompatibility of the optimized scaffold.
- To evaluate the scaffold's potential for in vivo and in vitro applications.
Main Methods:
- Employed gradient sodium dodecyl sulfate (SDS) and other reagents for liver tissue decellularization via perfusion.
- Assessed extracellular matrix preservation and scaffold architecture post-decellularization.
- Evaluated scaffold biocompatibility through heterologous animal embedding and HepG2 cell perfusion culture.
Main Results:
- Achieved rapid decellularization in approximately 5 hours, significantly faster than previous methods.
- Maintained extracellular matrix integrity with minimal inflammatory cellular infiltration or structural damage.
- Demonstrated high HepG2 cell engraftment efficiency (86±5%) and superior albumin and urea synthesis compared to 2D cultures.
Conclusions:
