Deferoxamine enhances corneal endothelial cell (CEC) viability and promotes wound healing by increasing vascular endothelial growth factor (VEGF) expression in vitro. This study highlights deferoxamine

Area of Science:

  • Ophthalmology
  • Cell Biology
  • Pharmacology

Background:

  • Corneal endothelial cells (CECs) are crucial for maintaining corneal clarity and function.
  • Impaired CEC viability and wound healing can lead to corneal pathologies.
  • Investigating novel therapeutic agents to support CEC health is essential.

Purpose of the Study:

  • To determine if deferoxamine influences CEC proliferation and wound closure in vitro.
  • To assess if deferoxamine treatment upregulates vascular endothelial growth factor (VEGF) expression in CECs.

Main Methods:

  • Porcine CECs were isolated and characterized using immunohistochemistry for Na+/K+-ATPase.
  • Cell viability and proliferation were assessed using WST-1 and BrdU assays.
  • Wound closure was evaluated using a wound closure assay, and VEGF mRNA expression was measured by rt-PCR.

Main Results:

  • Deferoxamine (200 µM) significantly increased CEC viability (121 ± 24%, p = 0.0024).
  • Deferoxamine significantly accelerated corneal endothelial wound closure at 100 µM and 200 µM (p < 0.0001).
  • Treatment with 200 µM deferoxamine significantly upregulated VEGF mRNA expression (1.67-fold, p = 0.0006).

Conclusions:

  • Deferoxamine enhances CEC viability and promotes wound healing in vitro.
  • The pro-healing effects of deferoxamine are associated with increased VEGF expression.
  • Deferoxamine shows potential as a therapeutic agent for maintaining corneal endothelial integrity.
