Area of Science:

  • Biomedical Engineering
  • Regenerative Medicine
  • Tissue Engineering

Background:

  • Liver transplantation is the only definitive treatment for end-stage liver disease.
  • Organ donor shortages significantly limit liver transplantation availability.
  • Liver bioengineering aims to create functional alternatives to address the organ supply-demand gap.

Purpose of the Study:

  • To review various liver decellularization techniques.
  • To discuss crosslinking methods for enhancing scaffold properties.
  • To cover the preparation of soluble extracellular matrix (ECM).

Main Methods:

  • Review of chemical, physical, and biological decellularization approaches.
  • Analysis of crosslinking strategies to improve scaffold biomechanics, degradation, and immune response.
  • Exploration of soluble ECM preparation techniques.

Main Results:

  • Decellularized liver scaffolds mimic the native microenvironment and retain ECM components.
  • Various decellularization methods have advantages and drawbacks affecting scaffold microstructure.
  • Crosslinking enhances scaffold integration with host tissue and influences reconstruction.

Conclusions:

  • Optimizing decellularization is crucial for preserving ECM integrity.
  • Crosslinking improves scaffold performance, promoting better integration and reconstruction.
  • Further research into decellularization and crosslinking is vital for advancing liver bioengineering.
