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 limbus is a unique anatomic structure that is highly innervated and vascularized yet sets the boundary for the avascularized cornea. The corneal epithelial stem cells are believed to reside at the limbus. The intrinsic and external molecular signals that modulate the differentiation and proliferation of the limbal stems cells are still largely unidentified because of a lack of known specific markers. In this study, we used microarray technology to identify the unique gene expression profile in the limbus by comparing directly to that of its immediate adjacent structures, the cornea and conjunctiva, in the vervet monkey (Chlorocebus aethiops sabaeus). Many new genes were found to be preferentially expressed in the limbus, and two new biological pathways, melanin metabolism and apoptosis, were among other previously known processes identified in the limbus. These findings may shed light on the molecular components of limbal stem cells and their niche. Experiment Overall Design: The study consisted of gene expression profile comparisons across three anatomical structures of the eye. The parts of the eye compared included the cornea, the conjunctiva, and the limbus.

Project description:Although there have been studies conducted on cornea and retina growth and development, postnatal gene expression studies on sclera growth during postnatal growth has not been well characterised. Given that the mouse genome has 85% homology to the human genome and has been completely sequenced, mouse model for the study of ocular growth has advantages over other animal models. Thus, we aimed to study the biology and genetics behind sclera growth during post-natal development in Balb/cJ mice as a means to understand genetic changes that cause scleral growth and development during post-natal eye development The purpose of this study was to identify the genes underlying the development of mouse sclera post-natal growth of the posterior chamber of the eye using microarray Total RNA was isolated from single cryogenically ground mouse sclera (n=30, 6 samples each from week 1-, 2-, 3-, 6-and 8-old mice), reverse-transcribed and hybridized onto a Affymetrix mouse gene 1.0 ST array.We sought to use microarray to determine the gene expression profiles of mouse sclera from different age groups and identify the developmental genes that are involved in postnatal ocular growth.

Project description:The sclera maintains and protects the eye ball, which receives visual inputs. The aim of this study is to identify characteristics of the human sclera as one of the connective tissues derived from the neural crest and mesoderm. We have here demonstrated microarray data of cultured human scleral cells. Keywords: sclera, cartilage
