Enhancing Ex Vivo Limbal Epithelial Cell Expansion on Amniotic Membrane: A Comparative Study of Monolayer (2D) Versus Sandwich (3D) Culture Configurations.

Purpose: This study compared two-dimensional (monolayer) and three-dimensional (sandwich) systems for expanding ex vivo limbal epithelial cells on amniotic membrane and evaluated the outcomes after transplantation into rabbits with experimentally induced limbal stem cell deficiency.

Methods: Evaluations included markers for progenitor cells, proliferation, apoptosis, and clinical monitoring for up to 63 days. In the monolayer culture, epithelial cells derived from limbal explants were expanded on amniotic membrane as the substrate.

Effect of metronidazole ophthalmic solution on corneal neovascularization in a rat model.

Purpose: To evaluate the effect of metronidazole ophthalmic solutions on corneal neovascularization (CNV) in a rat model.

Methods: A chemical burn was created in the right central cornea of 40 rats. Animals were randomized and distributed into four study groups (n = 10 rats per group) designated Met_0.
