Overview
This protocol outlines the use of the cornea pocket assay model to evaluate the angiogenic effects of basic FGF. By creating a pocket in the cornea and inserting a basic FGF pellet, researchers can induce robust blood vessel growth from the limbal vessels towards the pellet.
Key Study Components
Area of Science
- Angiogenesis
- Ophthalmology
- Vascular biology
Background
