Abstract
The complex investigation of the biological properties of the triploid cell strain derived from a spontaneous abortus was carried out. Cytomorphological, autoradiographic, cytochemical, biochemical and immunochemical investigation showed that, according to most of the investigated properties, triploid cells did not differ from normal diploid cells. The cells had normal form, were well orientated, revealed expressed fibrillar apparatus and viability in the culture during 15–17 passages. The decrease of the alkaline phosphatase level, increase of acid phosphatase, lactate and malatdehydrogenase and greater nuclei area were the essential differences from the control. The cells had normal mitotic cycle parameters and the antigenic spectrum was practically identical to the normal cells.
