Culture & characterisation of limbal epithelial cells & oral mucosal cells.
BACKGROUND & OBJECTIVES Sources of autologous tissue that can functionally replace the corneal epithelium have been considered as an alternative to allogenous limbal transplants for limbal stem cells deficiency (LSCD). The aim of the present study was to compare the characterization of oral mucosa with limbal epithelial cells by markers using reverse transcriptase polymerase chain reaction (RT-...
متن کاملComparison 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 کاملculture and proliferation of human limbal stem cells in vitro
purpose: to evaluate the properties of cultured limbal stem cells for corneal surface reconstruction. methods: specimens of limbal explants were prepared from the eye bank of i.r. iran. the explants were cultured and expanded on acellular amniotic membrane for 21 days. the cultured cells were evaluated for expression of connexin 43 and keratinine k3 by immunocytochemistry and expression of k12 ...
متن کاملAngiogenesis potential of human limbal stromal niche cells.
PURPOSE The perivascular localization of stem cell (SC) niches suggests the presence of a vascular niche. We aimed to determine the angiogenesis potential of limbal niche cells (NCs). METHODS Human limbal NCs were isolated and serially passaged on plastic or coated Matrigel in embryonic SC medium containing BFGF and leukemia inhibitory factor before being reseeded in 3D Matrigel. Expression o...
متن کاملVariations of the Normal Human Limbal Stem Cells Detected by In Vivo Confocal Microscopy
Background To report normal variations of the limbal structures using in vivo laser scanning confocal microscopy. Methods: This was a retrospective study of fourteen eyes from 11 healthy individuals. Confocal imaging of cornea and limbus was performed using Heidelberg Retina Tomograph III Rostock Corneal Module. Results: The typical structure of the palisades of Vogt (POV) was detected ...
