Area of Science:

  • Regenerative Medicine
  • Biomaterials Science
  • Hepatology

Background:

  • Allogeneic liver transplantation is limited by donor scarcity and high costs.
  • Engineered livers using de-cellularization and re-cellularization present a promising alternative.
  • Current engineered livers have limited in vivo functionality.

Purpose of the Study:

  • To review current de-cellularization and re-cellularization strategies for liver engineering.
  • To highlight challenges in creating functional, re-engineered livers.
  • To discuss future directions for liver regeneration.

Main Methods:

  • Review of existing literature on de-cellularization and re-cellularization techniques.
  • Analysis of studies in animal models, particularly rat models.
  • Identification of critical factors in extracellular matrix preservation and cell seeding.

Main Results:

  • De-cellularization requires preserving native extracellular matrix ultrastructure.
  • Re-cellularization protocols need optimization regarding cell types and seeding strategies.
  • Existing engineered livers demonstrate short-term in vivo function.

Conclusions:

  • Significant challenges remain in achieving long-term functional re-engineered livers.
  • Further research into de-cellularization and re-cellularization is crucial.
  • Advancements may lead to the regeneration of viable, functional livers.
