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 کاملPellet cryopreservation for chicken semen: effects of sperm working concentration, cryoprotectant concentration, and equilibration time during in vitro processing.
The aim of the study was to standardize the pellet cryopreservation procedure for chicken semen. Mericanel della Brianza male chicken breeders (Italian breed) were used. Pooled semen samples were processed according to the following conditions: (1) dilution in prefreezing extender to 1 versus 1.5 bill cells/mL sperm working concentration (SWC); (2) 6% versus 9% dimethyl acetamide (DMA) concentr...
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 ...
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...
