Method for selective quantification of immune and inflammatory cells in the cornea using flow cytometry

Area of Science:

• Ophthalmology
• Immunology
• Cell Biology

Background:

• The cornea's transparency is crucial for vision and it protects against environmental factors.
• Immune and inflammatory cells within the cornea play a key role in processes like angiogenesis, opacity, and graft rejection.
• Understanding corneal cellular mechanisms is vital for improving corneal transplantation outcomes and developing new therapies.

Purpose of the Study:

• To describe a protocol for preparing corneal cells for flow cytometry analysis.
• To enable systematic investigation of corneal immunity, inflammation, angiogenesis, and wound healing.
• To facilitate the study of cellular mechanisms in corneal graft survival and therapeutic interventions.

Main Methods:

• Detailed protocol for corneal preparation, including excision, digestion, and cell staining.
• Flow cytometry technique for assessing corneal cells.
• Experimental model for analyzing corneal immune responses and healing processes.

Main Results:

• The protocol provides a straightforward method for isolating and analyzing corneal cells.
• The model allows for the systematic study of various corneal biological processes.
• The approach is applicable to evaluating therapeutic molecules and drug efficacy.

Conclusions:

• This protocol offers a valuable tool for advancing research in corneal biology and transplantation.
• The methodology supports the investigation of immune cell functions in the cornea.
