Variations 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 کاملRole of reduced folate carrier in intestinal folate uptake.
Studies from our laboratory and others have characterized different aspects of the intestinal folate uptake process and have shown that the reduced folate carrier (RFC) is expressed in the gut and plays a role in the uptake process. Little, however, is known about the actual contribution of the RFC system toward total folate uptake by the enterocytes. Addressing this issue in RFC knockout mice ...

متن کاملLabel-free in vitro visualization of particle uptake into human oral buccal epithelial cells by confocal Raman microscopy.
In this study, we present confocal Raman microscopy for chemically selective analysis of a human buccal epithelial cell layer with a focus on label-free visualization of particle uptake into the cells. We demonstrate the suitability and benefit of this analytical technique in comparison to confocal fluorescence microscopy for three dimensional imaging of in vitro cell models.
متن کاملAugmentation of reduced folate carrier-mediated folate/antifolate transport through an antiport mechanism with 5-aminoimidazole-4-carboxamide riboside monophosphate.
5-Aminoimidazole-4-carboxamide riboside (AICAR), an agent with diverse pharmacological properties, augments transport of folates and antifolates. This report further characterizes this phenomenon and defines the mechanism by which it occurs. Exposure of HeLa cells to AICAR resulted in augmentation of methotrexate, 5-formyltetrahydrofolate, and 5-methyltetrahydrofolate initial rates and net upta...
