| Popis | The structural organisation of chromatin in eukaryotes plays an important role in a number of biological processes. Our results provide a comprehensive insight into the nuclear topography of human peripheral blood granulocytes, mainly neutrophils. The nuclei of granulocytes are characterised by a segmented shape consisting of two to five lobes that are in many cases connected by a thin DNA-containing filament. The segregation of chromosomes into the nuclear lobes was studied using fluorescence in situ hybridisation (FISH). We were able to distinguish different topographic types of granulocytes on the basis of the pattern of segregation. Five topographic types were detected using, dual-colour FISH in two-lobed nuclei. The segregation of four sets of genetic structures could be studied with the aid of repeated FISH and a large number of topographic types were observed. In all these experiments a non-random distribution of chromosomes into nuclear lobes was found. |
