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:

The optimized gradient ionic detergent method efficiently produces decellularized liver scaffolds.
The resulting scaffolds exhibit satisfactory biocompatibility for both in vivo and in vitro applications.
This technique offers a promising approach for liver tissue engineering and regenerative medicine.
