The relationship between cell shape and function has long been of interest. However, although the behaviour of the cytoskeleton during the cell cycle has been studied extensively variations in the shape and three-dimensional substructure of the nucleus are less well documented. The spatial distribution of chromatin has previously been studied by a… (More)
Large-scale chromatin organization is likely to play an important role in epigenetic control of gene expression. This implies that after mitosis the correct chromatin organization must be re-established in the nuclei of the two daughter cells. Here we analyze the dynamic behavior of chromatin during the transition from late anaphase to G1 in dividing HeLa… (More)
For the purpose of automating a clinical diagnostic apparatus to quantify the deformability of human red blood cells, we present an automated image analysis procedure for on-line detection of the cell shape based upon the method of parametric deformable templates.
The fluorescence intensity image of an axially integrated through-focus series of a thin standardized uniform fluorescent layer can be used for image intensity correction and calibration in sectioning microscopy. This intensity image is in fact available from the earlier introduced Sectioned Imaging Property (SIP) charts (Brakenhoff et al., 2005). It is… (More)
Confocal Scanning Laser Microscopy (CSLM) is particularly well suited for the acquisition of 3-dimensional data of microscopic objects. In the CSLM a specific volume in the object is sampled during the imaging process and the result is stored in a digital computer as a three-dimensional memory array. Optimal use of these data requires both the development… (More)
