[MORPHOLOGY OF NCTC CELLS ONE DAY AFTER RESEEDING]

Development of regenerative medicine based on the use of stem cells is substantially dependent on the prediction of the changes that the cells undergo after culturing them in vitro. Therefore, the accumulation of knowledge in the field, which can be denoted as biology of cells in culture, is of special importance. Features of functioning cells in vitro is better to study in the permanent cells lines as their morphological and functional characteristics in numerous passages can be regarded as the result of adaptation of cells to grow outside the body. The aim of the present study was to test whether there is a relationship between the density of the cell culture prior to the formation of a monolayer of cells and morphometric parameters of the cells. The NCTC fibroblast-like cells (clone 929 were examined one day after reseeding. By this time, the culture density was such that there was virtually no direct contact between the cells. The cell area, spreading and polarization coefficients were used to characterize the cells. It has been shown that, in the same culture flask, the cells in the areas with a higher density of cells are smaller than in areas of lower density. At the same time, polarization of cells increases by increasing the cell density. Such cell reaction may be the result of the remote transfer of information between the cells. Analysis of the data obtained allows us to assume that the change in shape of the cells is related to early steps of monolayer formation.
