Comparison of Ultra Structure and Gene Expression of Cultured Limbal Stem Cells and Fresh Conjunctival, Limbal and Corneal Tissues
Purpose: The present study intends to show the characteristics of cultured limbal stem cell (CLSCs) and to compare them with normal Conjunctival (C), Limbal (L) and Cornea (K) tissues. Materials and Methods: The expressions of a set of genes potentially involved in differentiation and stemness function of limbal stem cells were assessed in freshly prepared limbal, corneal, and conjunctival tis...
متن کاملThe Limbal Epithelial Progenitors in the Limbal Niche Environment
Limbal epithelial progenitors are stem cells located in limbal palisades of vogt. In this review, we present the audience with recent evidence that limbal epithelial progenitors may be a powerful stem cell resource for the cure of human corneal stem cell deficiency. Further understanding of their mechanism may shed lights to the future successful application of stem cell therapy not only to the...
متن کاملThe phenotype of limbal epithelial stem cells.
PURPOSE The purpose of this study was to identify phenotypic markers of human limbal stem cells in fetal and adult corneas. METHODS RNA from microscopically dissected superficial limbal and central fetal (18 weeks) corneas was amplified and used to generate P(32)-labeled, reverse-transcribed antisense RNA that was linearly amplified and hybridized to a focused stem cell cDNA microarray. Diffe...

متن کاملLimbal epithelial crypt: a model for corneal epithelial maintenance and novel limbal regional variations.
OBJECTIVE To determine the distribution of cell membrane proteins and extracellular matrix proteins around the limbal epithelial crypt (LEC) compared with adjacent limbus and corneal epithelium. METHODS Serial histological sections of human corneoscleral limbus rims were stained with antibodies of interest by standard immunohistochemistry. RESULTS Superficial cells of the limbus were desmog...
