[The maternal-fetal system as an object for the study of mechanisms of the physiologic effect of weightlessness].
The place of embryological investigations in the program of mammalian experiments onboard the Cosmos biosatellites is discussed. The mother-fetus system is viewed as a specific loading test for studying the reserve potentials of the mammalian body in microgravity. It has been demonstrated that mammalians (Wistar rats) flown during the third term of their pregnancy can maintain homeostasis of the developing fetus within the limits that provide the normal development of physiological functions. Significant individual variations in animal responses to microgravity have also been found.
