This work studies the mechanisms of dysdifferentiation at cell neoplastic transformation based on the example of heterogeneity of the cell populations that form malignant tumors. Two natural fractions of Zajdela rat hepatoma cells are revealed that d

This work is devoted to the study of molecular and cellular mechanisms of disdifferentiation during neoplastic transformation of cells by investigating the malignant tumor cell heterogeneity. We have revealed two cell fractions of hepatoma Zajdela wh

The prometaphase karyotype of cell line PK contains two heteromorphous pairs of nucleolus organizers that belong to chromosomes 8a and 8, and to 10L and 10s. It was proposed that such heteromorphism may promote chromosome differentiating of interphas

Mammalian nucleolar organizers (NORs) contain ribosomal (rRNA) genes associated with argyrophilic proteins and can be specifically stained by silver. These genes are clustered in four loci of PK meta- and submetacentric chromosomes 8 and 10. Accordin

In accordance with molecular biology data reported elsewhere, homologous interphase X-chromosome territories differ greatly in the abundance of inactive condensed chromatin. On the other hand, a three dimensional FISH (3D FISH) method has revealed th

Natural diversity in peripheral and PHA-stimulated lymphocytes seen in the same donors was studied using digitized streak photo of living cells in observational camera. Cells were monitored for 5-8 h at the superior limit of optical resolution by mea

Intact and surface stretched amembraneous nuclei of Entamoeba histolytica (Rhizopoda, Lobosea, Entamoebidae) trophozoites were studied by light and electron microscopy. A moderately dense karyosome about 1.5 microns in diameter, localized in the cent

Viewed by light microscopy, the majority of lymphocytes in smears of human peripheral blood display a deep staining (with any chromatin- or DNA-specific dye) of the nucleus consisting of densely aggregated chromatin in addition to one or several smal

Densely aggregated chromatin of mature human or animal peripheral lymphocytes is inaccessible for structural investigation on preparations of both intact cell and conventionally spread chromatin. Giemsa- and DAPI-positive "free chromatin" structures,

Preparations of surface stretched amembranous nuclei and mitotic figures were used for revealing the high order nuclear and chromosomal structures. The preparations were obtained by dropping amembraneous nuclei and mitotic figures suspension in metha
