Area of Science:

  • Ophthalmology
  • Regenerative Medicine
  • Cell Biology

Background:

  • The human corneal endothelium has limited regenerative capacity in vivo.
  • Corneal transplantation has been the primary treatment for endothelial damage.
  • In vitro cultivation of human corneal endothelial cells (HCEC) presents a potential therapeutic alternative.

Purpose of the Study:

  • To review methods for in vitro cultivation and transplantation of HCEC.
  • To explore HCEC as an alternative to donor cornea transplantation.

Main Methods:

  • Established defined cell culture conditions with growth factors for HCEC proliferation.
  • Transplanted in vitro cultured HCEC onto the Descemet membrane of donor corneas.
  • Utilized a SV40-transformed HCEC cell line for high cell density.

Main Results:

  • Achieved in vitro proliferation of HCEC with phenotypic and proliferative variations based on culture conditions.
  • Demonstrated successful monolayer formation of transplanted HCEC on donor corneas.
  • Confirmed monolayer integrity and endothelial pump function post-transplantation.

Conclusions:

  • Successfully established methods for transplanting HCEC to reconstruct human corneas.
  • Corneal endothelial cell transplantation is a promising future option for high-quality corneal grafts.
  • Potential for direct manipulation of diseased endothelium in patients with corneal endothelial dystrophies.
