Area of Science:

  • Biomedical Engineering
  • Hepatology
  • Regenerative Medicine

Background:

  • Liver failure necessitates artificial support systems to replace hepatic functions.
  • Bioartificial systems integrate metabolically active cells for enhanced functionality.
  • Existing artificial systems lack the complex biological functions of a native liver.

Purpose of the Study:

  • To review current bioartificial liver support (BALS) systems.
  • To provide an overview of experimental and clinical applications.
  • To identify challenges and limitations in BALS development.

Main Methods:

  • Review of existing literature on bioartificial liver support systems.
  • Analysis of cell sources and bioreactor designs.
  • Examination of clinical study data for safety and efficacy.

Main Results:

  • Various BALS have been developed, incorporating cellular components.
  • Several systems have undergone clinical trials to assess safety.
  • Key challenges include cell source selection and bioreactor sophistication.

Conclusions:

  • BALS offer a promising approach to support liver function.
  • Further research is needed to optimize cell sources and bioreactor technology.
  • Overcoming current limitations is crucial for clinical success of BALS.
