Transplantation of preserved amniotic membrane (AMT) is becoming a valuable technique for reconstruction of the ocular surface. However the mechanism is largely unknown. We investigated the hypothesis that amniotic membrane has an effect on ocular inflammation
Methods: In tissue culture keratocytes were stimulated with inflammatory mediators. mRNA for various CXC chemokines was quantified by dot and northern blots.
Results: Clinically, AMT caused a consistent reduction of inflammation when applied to corneal epithelial defects and ulcers. In vitro keratocytes seeded on amniotic membranes showed less expression of chemokines (Il-8, gro-alpha, ENA-78) compared to cells seeded on plastic.
Discussion: AMT is a valuable tools for ocular surface reconstruction. Our findings offer a mechanism by which amniotic membrane suppresses inflammation when transplanted to the surface of the eye.
