[Giant cells in the placenta of the bactrian camel in the fetal period of development].
Polyploid giant cells resulting from differentiation of normal cytotrophoblast cells were found in the composition of the placenta cytotrophoblast of the Bactrian camel. In the placenta of the Bactrian camel the transformation of cytotrophoblast cells into multinuclear giant cells is realized via endomitotic polyploidization and distinctly reflects active synthetic processes occurring in these cells related with the trophic function of the placenta. It may be supposed that giant cells of the placenta of female Bactrian camels also participate in the endocrinous function of the placenta. Their histolitical function is completely excluded.
