Liver Regeneration

4.1K
The liver is an important organ in vertebrates that plays an essential role in metabolism. It is also responsible for storing and redistributing nutrients such as carbohydrates, fats, and vitamins in the body. Additionally, the liver releases bile salts which are critical for digesting food and eliminating toxic metabolites from the body.
Cells of Liver
The liver comprises four major types of cells— hepatocytes, stellate, Kupffer, and sinusoidal endothelial cells. The hepatocytes are...

Area of Science:

  • Biomedical Engineering
  • Regenerative Medicine
  • Hepatology

Background:

  • The liver's in vivo regeneration capacity contrasts with challenges in in vitro liver tissue engineering.
  • Conventional 3D hepatocyte cultures have limitations for complex liver tissue construction.

Purpose of the Study:

  • To review advancements in 3D liver cell culturing for in vitro tissue reconstruction.
  • To explore micro-, macro-, and mesoscale approaches in liver tissue engineering.
  • To assess the current status and future directions of engineered liver development.

Main Methods:

  • Discussion of conventional 3D hepatocyte cultures.
  • Summary of recent advances in 3D liver cell culturing.
  • Analysis of microfluidics (bottom-up) and whole-organ bioengineering (top-down) strategies.
  • Consideration of mesoscale integration approaches.

Main Results:

  • Microfluidics enables bottom-up microscale liver tissue engineering.
  • Whole-organ bioengineering represents a top-down macroscale approach.
  • Mesoscale strategies aim to bridge micro- and macroscale engineering.
  • Ongoing multiscale studies have not yet produced clinically applicable engineered livers.

Conclusions:

  • Integration of micro-, macro-, and mesoscale strategies is crucial for advancing liver tissue engineering.
  • Further research is needed to overcome challenges in creating clinically viable engineered livers.
  • Multiscale approaches are essential for understanding liver reconstruction.
  • Despite progress, clinical application of engineered livers remains a future goal.
