RESUMO
It is shown that in case of a secretory action of amnion, a specific protein characterized by an immunostimulating action is brought to the amniotic liquid. Its participation in the embryogenesis processes is assumed.

Solvable proteins of caruncles have been studied at pregnancy. A group of solvable proteins absent in the blood serum, amniotic fluid, fetal placenta and uterus mucosa independent of the phase of ovary development is revealed. Molecular weight of most of them is 40 kDa. It is supposed that the found proteins take part in embryogenesis.

When studying peculiarities of the protein composition of amniotic fluid in cows a group of proteins with molecular mass below 60 kDa was found. There are no such proteins in blood of those animals. It is supposed that these proteins can take active part in embryogenesis processes.
