Area of Science:

  • Biomaterials Science
  • Tissue Engineering
  • Hepatocyte Biology

Background:

  • Hepatocyte culture in bioreactors is crucial for liver function studies and therapies.
  • Enhancing cell attachment and function on biomaterial scaffolds remains a challenge.

Purpose of the Study:

  • To design and prepare a chitosan nanofiber scaffold for hepatocyte culture.
  • To investigate the effects of this scaffold on hepatocyte adhesion, viability, and liver-specific functions.

Main Methods:

  • Electrospinning was used to fabricate chitosan nanofiber scaffolds.
  • Hepatocyte adhesion, viability assays, and measurements of liver functions (urea synthesis, albumin secretion, cytochrome P450 activity, glycogen synthesis) were performed.

Main Results:

  • Hepatocytes cultured on the chitosan nanofiber scaffold showed enhanced adhesion and viability compared to regular chitosan film.
  • Key liver functions, including urea synthesis, albumin secretion, and cytochrome P450 activity, were 1.5 to 2 times higher on the scaffold.
  • Glycogen synthesis was also significantly increased.

Conclusions:

  • The chitosan nanofiber scaffold provides a superior environment for hepatocyte culture.
  • This scaffold holds potential for applications in liver tissue engineering and bioreactor-based liver support systems.
