Project description:To date, there is no specific marker for limbal epithelial stem cells. The identification of a marker that is expressed in the limbal epithelium but not in the cornea or conjunctiva epithelium has been a growing need. To search for limbal-specific marker(s), we performed preferential gene profiling in the limbus in direct comparison to that in the cornea and conjunctiva using microarray technique. This study consisted of gene expression profiles comparing the limbus to the cornea and conjunctiva.

Project description:The identification of a marker that is expressed in the conjunctival epithelium but not in the corneal epithelium has been a growing need. A more specific marker of limbal and conjunctival epithelia would be necessary to detect non-corneal epithelial cells on the corneal surface. To search for conjunctival specific marker(s), we first performed preferential gene profiling in the conjunctiva in direct comparison to that in the cornea using microarray technique. The study consisted of gene expression profiles comparing the cornea and conjunctiva.
Project description:Comparison of endogenous gene expression differences between pterygium and conjunctiva tissues RNA from donor-matched pterygium and conjunctiva tissues obtained from four patients were evaluated for differences in gene expression
Project description:To identify dysregulated molecules between pterygium tissues and uninvolved conjunctiva tissues from the same eye, we performed whole genome microarray expression profiling. Total RNA from four pairs of pterygium and uninvolved conjunctiva tissues from the same eye was extracted and used for microarray experiments.
Project description:We mapped the cell types present in human conjunctiva tissue, organoids and air-liquid interface cultures exposed or not to IL4/13.
Project description:The conjunctival epithelium covering the eye consists of two main differentiated cell types: mucus-producing Goblet cells and ‘keratinocytes’ of unknown function. Here, we describe long-term expanding organoids representing human conjunctiva. To check if interleukins may boost secretome expression, we stimulated the organoid cells with pleiotropic anti-inflammatory cytokines interleukin-4 and IL-13. Secretions were identified by shotgun MS to quantitatively enriched secreted proteins.
