Human Umbilical Cord-Derived Mesenchymal Stem Cells Promote Corneal Epithelial Repair In Vitro

Area of Science:

• Ophthalmology
• Regenerative Medicine
• Stem Cell Biology

Background:

• Corneal injuries are a major cause of blindness globally.
• Current treatments like corneal transplantation face challenges including donor shortage and graft rejection.
• Alternative therapies are needed for end-stage corneal diseases.

Purpose of the Study:

• To investigate the potential of human umbilical cord-derived mesenchymal stem cells (UC-MSCs) in corneal epithelial repair.
• To characterize UC-MSCs for relevant surface and lineage markers.

Main Methods:

• Isolation, culture, and characterization of UC-MSCs.
• Immunofluorescence staining for mesenchymal (CD73, CD90, CD105, CD34) and ocular surface/epithelial (PAX6, WNT7A, CK-8/18) markers.
• In vitro scratch assay to assess corneal epithelial wound healing potential.

Main Results:

• UC-MSCs exhibited plastic adherence and trilineage differentiation potential.
• UC-MSCs expressed key mesenchymal, epithelial, and ocular lineage markers.
• UC-MSCs significantly promoted corneal epithelial cell proliferation and repair in vitro.

Conclusions:

• Human umbilical cord-derived mesenchymal stem cells possess characteristics suitable for corneal tissue repair.
• UC-MSCs demonstrate potential as a therapeutic agent for injury-induced corneal diseases.
• These cells offer a promising non-ocular stem cell source for treating corneal blindness.
