Area of Science:

  • Ophthalmology
  • Regenerative Medicine
  • Biomaterials Science

Background:

  • Corneal transplantation faces challenges including immune rejection and limited donor availability.
  • Tissue engineering of the cornea aims to overcome these limitations by creating bioengineered corneal tissues.
  • Cultivated corneal epithelial cells expanded ex vivo are already used clinically, but further advancements are needed.

Purpose of the Study:

  • To review the current state of tissue-engineered corneal epithelium.
  • To introduce a novel method for transplanting cultivated corneal cell sheets.
  • To present research findings on a new cell sheet transplantation technique.

Main Methods:

  • Utilizing temperature-responsive culture dishes for cell sheet expansion.
  • Cultivating corneal epithelial stem cells ex vivo.
  • Developing a method for transplanting engineered corneal cell sheets.

Main Results:

  • The study reviews existing tissue-engineered corneal epithelium research.
  • The research program focuses on a novel cell sheet transplantation method.
  • Preliminary results indicate potential for improved corneal regeneration.

Conclusions:

  • Tissue-engineered corneal epithelium holds promise for treating corneal diseases.
  • The developed temperature-responsive culture dish method offers a potential solution for cell sheet transplantation.
  • Further research is ongoing to refine this technique for clinical application.
