| Research Abstract |
Corneal suture is a surgical procedure used to treat corneal trauma or for cases of corneal transplantation. However, suture-related inflammatory cell infiltration (dynamics) in the cornea has yet to be analyzed in detail. In this study, we used immune cells labeled mice, which are gene-targeted mice expressing enhanced green fluorescent protein (EGFP), and intravital imaging, which is a technique used to analyze cellular and molecular dynamics stereoscopically and time-dependently in an in vivo animal model. LysM strongly positive cells (neutrophils) are present in the stroma of only limbus at normal condition, but they move to the entire stroma of the cornea after alkali injury. We also found that neutrophils migrated from limbal capillary loop and infiltrated to the corneal suture. Using Intravital Imaging, we could find the dynamic features underlying various physiological and pathological conditions in cornea.
