Visualization of Endothelial Actin Cytoskeleton in the Mouse Retina [PDF]
, 2012 Angiogenesis requires coordinated changes in cell shape of endothelial cells (ECs), orchestrated by the actin cytoskeleton. The mechanisms that regulate this rearrangement in vivo are poorly understood - largely because of the difficulty to visualize ...

RETINAL VESSEL ANALYSIS - NEW POSSIBILITIES [PDF]
Biomedizinische Technik/Biomedical Engineering, 2002 Retinal Vessel Analysis is a new technique to assess behavior of large retinal vessels based on diameter measurements. The Retinal Vessel Analyzer (RVA) measures continuously on-line obtaining data in relation to time and local position. Possible analysis tools include (a) Time Course Analysis of physiological, pathological, or therapy induced changes;
