Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the cellular identity?Differentiated fibroblasts residing in the corneal stroma
2. What is the apoptotic potential?Susceptible to programmed cell death (apoptosis) following corneal trauma, influencing healing dynamics
3. What are corneal keratocytes and why are they important?They are tiny cells in the eye that keep the cornea clear and strong by making and organizing collagen fibers. They help the eye stay transparent and protect it.
4. How do corneal keratocytes help heal a scratched eye?When the cornea is hurt, keratocytes become active, move to the injury, and turn into cells that produce collagen to close the wound. They help the cornea heal quickly.

Extracellular Matrix (ECM): A network of molecules outside cells that provides structural and biochemical support to surrounding cells.
Myofibroblast: A cell that possesses characteristics of both smooth muscle cells and fibroblasts, crucial for wound contraction and tissue repair.
Keratoconus: A progressive eye condition where the cornea thins and begins to bulge outwards into a cone shape.
