[Dynamics of the morphofunctional status of cell cultures exposed to variations in the geomagnetic field at high latitudes].
The goal of this research is to study a dependence between dynamics of the biological parameters, characterized the state of the cell cultures, and variations of geomagnetic field (GMF) in the quiet and disturbed conditions. The investigations were carried out on geophysical recording site in high-latitude regions. Geophysical and biological observations were conducted simultaneously and at the same place. Continuous cell lines of mouse, hamster and pisces were used in experiments. Morpho-functional characteristics, including the percentage of polynuclear cells were estimated. Has been shown that dynamic of morphofunctional state of cell culture associated with GMF variations. Geomagnetic activity (GMA) abrupt change is followed by a stepwise changes the state of cell cultures. Changes is properties of cell surface are related to cell fusion, the appearance of heterokaryons, enlargement of cellular adhesion and aggregation. Enhancement of morpho-functional variety in cellular populations involving a reorganization of nuclear material demonstrate a possible regulatory and evolutionary part of GMF variations.
