Many studies have implicated cell-surface lectins in heterologous cell-cell adhesion, but little is known about the participation of lectins in cellular adhesion in homologous cells. Here, we show the development of a cell model for investigating the direct role of a cell-surface lectin in homologous cell-cell adhesion. Parenchymal cells were isolated from caprine liver using a perfusion buffer, and dispersed in a chemically defined modified Ringer’s solution. These cells undergo autoagglutination in the presence of Ca2+. The autoagglutinated cells can be dissociated specifically with D-galactose (50 mM), which also inhibits the liver cell autoagglutination event. The blood serum protein fetuin has no effect on liver cell autoagglutination, whereas desialylated fetuin (100 μM), with its terminal D-galactose residue, showed a high affinity for blocking the autoagglutination event. The data demonstrates the occurrence of a Ca2+-dependent D-galactose-specific lectin and a lectin receptor on the parenchymal cells. Furthermore, it shows that the observed autoagglutination event is caused by the interaction of the cell-surface lectin with its receptor on the neighbouring homologous cells. The data supports the view that homologous cell-cell contact in mammalian tissues is triggered by such lectin-receptor interaction and that the previously reported cell-surface adhesive proteins serve as a secondary force to strengthen cell adhesion. This cell model could be extremely useful for investigating the direct role of cell-surface lectin and its receptor in homologous cell adhesion in a variety of tissues under normal and pathological conditions.

Eggs within paruterine capsules of gravid proglottids of Distoichometra bufonis were examined by light and transmission electron microscopy. The embryonic capsule was membranous, but was immediately underlain by a non-uniform subcapsular lamina that was an intracellular component of the outer embryonic envelope. The subcapsular lamina was thick and semi-rigid on anterior and posterior poles, but thin and membranous laterally, giving the entire egg a laterally oblong shape. In contrast, the embryophore was spherical and uniform in thickness. The paruterine capsule walls were derived from layers of flattened processes of medullary parenchyma cells lined internally with a layer of uterine epithelium. All these layers extended inward to form parenchyma-uterine partitions segregating each egg into an individual chamber. The uterine epithelium was very thin, syncytial, and contained numerous vesicles. Little uterine secretory product occurred in the uterine lumen or on the outer surface of the embryonic capsule. Except for the unique subcapsular lamina, most features of the eggs and paruterine capsule resembled those of other nematotaeniid species. The paruterine capsule wall was similar to that of Mesocestoides lineatus, a species whose paruterine organ lacks parenchyma-uterine partitions.

Six seedling hypocotyl anatomical characters of sugar beet diploid lines and triploid hybrids were measured. Root yield and sugar content of these lines and hybrids were evaluated in replicated field trials. Some of the studied hypocotyl characters: the diameter of the central core, the diameter of parenchymatic cells outside the central core and the width of xylem, correlated negatively with sugar content and positively with root yield. This suggests that these parameters can be used in preliminary selection of sugar-beet breeding material. Introducing such criteria into the breeding process could speed up the selection and reduce the number of expensive field trials.

Fruits and vegetables are built mainly of thin walled parenchyma cells highly susceptible to mechanical damage. According to experimental investigation of relationship between cells geometrical parameters and mechanical properties of tissue a new efficient method of structure reconstruction and parametrisation is elaborated and presented in this paper. Special sample preparation and way of image taking by Confocal Scanning Laser Microscope with fluorescence mode allows obtaining images of any number of cells. Unique computer procedure based on morphological operators was created that allows analysing automatically any number of images with extracting geometrical parameters of each cell separately. The method was tested on potato and carrot tissue. Results show that the method is fast and gives proper cell reconstruction for both materials. In order to decrease error of incorrect reconstruction, possibility of manual correction was introduced to the procedure.

Vascular storage parenchyma cells of carrot roots were treated with methanol solutions of radicinin and epiradicinol produced by Alternaria radicina and with alternariol and alternariol methyl ether produced by A. alternata at concentrations of 25 µg/ml and 250 µg/ml, as well as culture filtrates of both fungi. Cell ultrastructure was observed by TEM. No visible changes were noted after treatment with 25 µg/ml toxin solutions. The most extensive plication of cell membranes, and sometimes also cell walls, and the formation of numerous vesicles in the cytoplasm, was observed in cells treated with the higher concentration of toxins. Plasma membrane withdrawal and vésiculation, microvacuole formation, and accumulation of plastoglobuli in chromoplasts also occurred. No changes in the structure of endoplasmic reticulum and dictyosomes were noted. The responses of cell structures to particular toxins were nonspecific. Treatment with culture filtrates from A. radicina resulted in the occurrence of osmiophilic, electron-dense substance in the cytoplasm and plastoglobuli. All alterations induced by filtrates were more extensive than those resulting from toxin solutions, but membrane integrity was not disturbed after any of the treatments.
