Liver Regeneration01:24

Liver Regeneration

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 large...

Area of Science:

  • Biomaterials Science
  • Regenerative Medicine
  • Hepatology

Background:

  • Chronic liver disease poses a significant global health challenge, with liver transplantation being the primary treatment but facing limitations.
  • The liver's natural regenerative capacity is often insufficient in chronic conditions, necessitating alternative regenerative strategies.

Purpose of the Study:

  • To review controlled release biomaterial-based platforms for enhancing liver regeneration.
  • To discuss hydrogels and nanoparticle systems as practical tools for clinical application.

Main Methods:

  • Examination of 3D scaffold-based and injectable hydrogels for liver regeneration.
  • Analysis of biomaterials for controlled release of growth factors, nucleic acids, cells, and extracellular vesicles.
  • Inclusion of nanoparticle systems for molecular-level release and modulation of oxidative stress/inflammation.

Main Results:

  • Biomaterial platforms enable local retention and controlled release of regenerative factors, overcoming limitations of endogenous repair.
  • Nanoparticles can precisely control molecular release and mitigate inflammation.
  • Considerations for anatomical, engineering, and imaging aspects crucial for clinical translation are addressed.

Conclusions:

  • Biomaterial-enabled regenerative therapies show potential as alternatives or bridges to liver transplantation.
  • Further research is needed to overcome barriers to wider clinical adoption of these gel composite systems.
