Project description:Whole human conjunctivae and human corneas were obtained from the National Disease Research Interchange (NDRI, Philadelphia, PA) and processed between 48 - 72 hr of death. No donor details apart from age, sex and cause of death were released. Criteria for inclusion were donor ages between 25 - 65 years old and overt physical integrity of the epithelium over the central cornea as revealed by a quick stain with 0.1 % Trypan blue. For each replicate experiment (Conjunctiva 1 and Cornea 1; Conjunctiva 2 and Cornea 2;Conjunctiva 3 and Cornea 3), RNA from two different corneal or conjunctival specimens was pooled and converted into cDNA. Appropriately fragmented biotin-labeled cRNA was hybridized to the HG-U133A GeneChips® (Affymetrix) oligonucleotide microarray following the manufacture protocol. Three separate experiments each including one conjunctival and one corneal cRNA pool were performed (Conjunctiva 1 and Cornea 1; Conjunctiva 2 and Cornea 2;Conjunctiva 3 and Cornea 3).

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:Gene methylation profiling of immortalized human mesenchymal stem cells comparing HPV E6/E7-transfected MSCs cells with human telomerase reverse transcriptase (hTERT)- and HPV E6/E7-transfected MSCs. hTERT may increase gene methylation in MSCs. Goal was to determine the effects of different transfected genes on global gene methylation in MSCs.
